Training Aids Tools like a blind dog collar or hoop can help alert your pet to obstacles in unfamiliar environments. Safety First Block off pools, cliffs, or areas with sudden drop-offs. Keep food and water bowls in a consistent spot, and use textured mats to help your pet identify their location. Create Safe Spaces Provide designated beds or mats with a unique texture to signal a safe place for rest and orientation. Navigate Stairs with Care Use textured mats at stair edges or consider installing a ramp if stairs are too challenging. Build Walking Confidence Stick to a couple of familiar walking routes. As your pet learns the paths, their confidence will grow. Consider a Companion A sighted dog companion can provide guidance and comfort, but ensure it’s the right fit for your family and your pet’s personality. You can also arrange for a friend’s dog to visit regularly. Patience Is Key Remember, this is a time of adjustment for your pet too. Be patient, offer reassurance, and celebrate small victories as they learn to navigate their world. You’re not alone in this journey—our team is here to support you every step of the way.
  • Cataracts in Dogs
  • Progressive Retinal Atrophy
    Understanding Progressive Retinal Atrophy (PRA) Progressive Retinal Atrophy (PRA) is a group of inherited diseases that gradually cause vision loss in dogs due to the degeneration of the retina. This condition is more common in certain breeds, including Cocker Spaniels, Poodles, Australian Cattle Dogs, Silky Terriers, and Labradors. Our goal is to help you understand PRA so you can make informed decisions for your pet and provide the best possible care during this journey. Signs and Symptoms PRA progresses slowly, with vision loss occurring over months or years: Early signs: Difficulty seeing in dim light (night vision), reluctance to go outside at night, or bumping into objects in low light. Owners may also notice an increased green reflection in their pet's eyes under artificial light. Later stages: Gradual loss of day vision and the development of cataracts (visible as white opacities in the pupil). Cataracts worsen vision loss by blocking light from reaching the retina. Unfortunately, because the vision loss is so gradual, many owners don’t notice a problem until the blindness is severe. Diagnosis Early detection is crucial. PRA can be diagnosed using: A thorough clinical eye examination. Chromatic PLR (Pupillary Light Reflex) testing. Electroretinogram (ERG) to assess retinal function. Treatment At this time, there is no treatment to reverse or halt PRA. However, management focuses on preventing complications associated with cataracts, such as: Uveitis (inflammation of the iris): Treated with cortisone drops to prevent further issues. Glaucoma (high pressure in the eye): Early treatment can help reduce discomfort and maintain eye health. While cataract removal is an option for other conditions, it is not effective for restoring vision in dogs with PRA. Prevention and Genetic Testing Because PRA is an inherited condition, understanding your dog’s genetics is vital: If PRA is identified, related dogs should be examined for the condition. PRA is typically inherited as an autosomal recessive trait, meaning both parents must carry the gene for it to be passed on. DNA blood tests are available to identify affected dogs and carriers, helping breeders make informed decisions to reduce the spread of PRA in future generations. How We Can Help At Animal Eye Services, we’re here to guide you through every step—offering expert diagnosis, management advice, and support. With proactive care and understanding, your dog can continue to lead a happy and fulfilling life.
  • Lens Luxation
    Understanding Lens Luxation in Dogs Lens luxation occurs when the lens, which is normally held in place behind the iris and pupil by tiny fibers called zonules, moves out of its proper position. This condition can cause significant discomfort and vision problems, requiring prompt attention and treatment. At Animal Eye Services, we’re here to help you understand lens luxation, its causes, and the treatment options available to support your pet’s eye health. What Is Lens Luxation? There are two types of lens luxation: Subluxation: The lens is partially displaced but still held in place by some zonules. Complete Luxation: The lens is entirely displaced because all the zonules have broken. Causes of Lens Luxation Lens luxation can be classified into two categories based on the cause: Primary Lens Luxation: Commonly seen in breeds such as Jack Russell Terriers, Miniature Fox Terriers, Tenterfield Terriers, and Cattle Dogs. Caused by genetic defects that weaken the zonules over time. Trauma can also cause lens luxation, though it’s rarely the sole cause. Secondary Lens Luxation: Occurs as a result of other eye conditions, such as: Glaucoma: Elevated pressure inside the eye weakens the zonules. Uveitis: Inflammation inside the eye damages the zonules. A luxated lens can also lead to secondary complications, including glaucoma. Signs of Lens Luxation If your dog has lens luxation, you may notice: Sudden vision loss. Pain or discomfort in the eye. Redness or swelling. A visible shift in the lens position. Treatment Options Treatment depends on the severity of the condition, the position of the lens, and the overall health of the eye: Medications: If the lens is loose but still behind the iris, special prescription drops can constrict the pupil and hold the lens in place. These drops must be used for life, as missing a dose can cause the lens to slip back into the front chamber. Surgical Intervention: Lens Removal (Lensectomy): Performed under general anesthesia using an operating microscope. The lens is removed through a small incision in the eye using specialized tools. While up-close vision may be fuzzy without a lens, most dogs maintain good general vision. Lens Repositioning: In some cases, the lens can be carefully moved back behind the iris and stabilized with medication. Risks and Prognosis Unfortunately, even with prompt treatment, some eyes affected by lens luxation may become blind or require removal due to uncontrollable pain. Early intervention and proper management can improve the chances of preserving vision and comfort. How We Can Help At Animal Eye Services, we specialise in diagnosing and treating complex eye conditions like lens luxation. If you notice signs of vision changes or discomfort in your dog, contact us immediately. Our team is here to guide you through the best treatment options and provide compassionate care for your pet.
  • Glaucoma
    Understanding Glaucoma in Pets Glaucoma is a serious eye condition caused by an increase in pressure inside the eye, often leading to vision loss and significant pain. This is a true ophthalmic emergency—prompt treatment is critical to preserving your pet’s comfort and vision. At Animal Eye Services, we understand how alarming glaucoma can be. We’re here to help you recognize the signs, understand the condition, and navigate the treatment options. Signs of Glaucoma Glaucoma can manifest through a range of symptoms. If you notice any of the following, seek veterinary care immediately: Redness in the eye A cloudy appearance in the eye Tearing or excessive discharge Vision loss An enlarged eyeball Unusual aggression or irritability Lethargy or lack of energy Loss of appetite What Causes Glaucoma? Glaucoma occurs when the eye's fluid (produced behind the pupil in the ciliary body) cannot drain properly through the natural pathway between the cornea and iris. This leads to a dangerous buildup of pressure. Think of it like a kitchen sink: if the drain is clear, water flows through without issue. But if the drain is blocked and water keeps running, the sink overflows. Similarly, when the fluid in the eye can't drain, pressure builds up, causing damage to the eye structures. Types of Glaucoma: Primary Glaucoma: Occurs without any underlying disease. Secondary Glaucoma: Caused by conditions like inflammation, trauma, or tumors that obstruct fluid drainage. Why Prompt Treatment Matters Glaucoma is an emergency. If the pressure in the eye remains elevated for even a few hours, permanent vision loss can occur. Early detection and immediate intervention are key to minimizing damage and relieving your pet’s pain. Treatment Options Treatment depends on the severity of the glaucoma, whether vision can still be preserved, and factors like your pet’s overall health and your family’s circumstances. Options may include: Medical Management: Medications to lower eye pressure. Laser Surgery: Helps reduce fluid production or improve drainage. Surgical Drainage Tubes: Implanted to assist with fluid outflow. Removal of a Blind, Painful Eye: Improves comfort when vision cannot be saved. Cosmetic Prosthesis: Provides an aesthetic solution if the eye needs removal. Each treatment has pros and cons, and the best course of action will be tailored to your pet's specific needs. During your consultation, we’ll discuss all options to help you make an informed decision. How We Can Help At Animal Eye Services, we’re here to support you through every step of diagnosis, treatment, and follow-up care. If you suspect glaucoma, contact us immediately—your pet’s comfort and vision depend on timely action.
  • Uveitis
    Understanding Uveitis in Pets Uveitis is a condition involving inflammation of the uveal tract, the part of the eye that contains blood vessels. This inflammation can cause discomfort, cloudiness, and even vision loss in severe cases. At Animal Eye Services, we’re here to help you understand this condition, its potential causes, and how it can be treated to protect your pet’s eye health. What Is the Uveal Tract? The uveal tract lines the inside of the eye and has three main parts: Iris: The colored part at the front of the eye. Ciliary Body: A specialized part that produces fluid inside the eye. Choroid: A structure under the retina at the back of the eye. Because the uveal tract contains blood vessels, inflammation can cause blood cells and debris to leak into the eye’s fluid-filled chambers, leading to visible changes and, in severe cases, vision loss. Signs of Uveitis If your pet has uveitis, you might notice: Cloudiness in the cornea. Redness around the edge of the eye. Excessive tearing or watery eyes. Squinting or sensitivity to light. Bleeding into the eye. Vision loss. Causes of Uveitis Uveitis can have a variety of underlying causes, which will be thoroughly assessed during your pet’s consultation. Common causes include infections, trauma, immune-mediated conditions, and other systemic diseases. Why Uveitis Needs Prompt Attention Severe uveitis can lead to serious complications that threaten your pet’s vision, including: Cataracts: Cloudiness of the lens. Adhesions: The iris sticking to the lens or cornea. Retinal Disease: Damage to the retina. Glaucoma: Increased pressure in the eye. Treatment for Uveitis Treatment focuses on: Reducing inflammation: Using medications to manage swelling and discomfort. Preventing complications: Protecting against long-term damage to the eye. Every pet’s treatment plan is tailored to their specific condition, based on the severity of the uveitis and its underlying cause. How We Can Help At Animal Eye Services, we’re committed to preserving your pet’s vision and comfort. If you notice any of the signs of uveitis, don’t delay—schedule a consultation so we can determine the best course of action for your pet’s care.
  • Dry Eye
    Understanding Dry Eye in Pets A healthy cornea and conjunctiva—the clear structures at the front of the eye—depend on a balanced and functioning tear film. When this tear film is disrupted, your pet may develop dry eye, a condition that causes discomfort, redness, and even vision loss if left untreated. At Animal Eye Services, we’re here to help you understand the causes, symptoms, and treatment options for dry eye, ensuring your pet’s comfort and eye health. What Is the Tear Film? The tear film is made up of three essential layers: Lipid Layer: The outermost layer, produced by Meibomian glands in the eyelids, prevents tear evaporation. Aqueous Layer: The watery middle layer makes up 95% of the tear film and is produced by the lacrimal gland behind the upper eyelid. Mucous Layer: The innermost layer helps the tear film adhere to the surface of the cornea. When one or more of these layers is compromised, the eye can’t stay properly hydrated, leading to dry eye. Causes of Dry Eye Dry eye has many potential causes, including: Congenital disorders: Common in puppies. Infections: Such as canine distemper virus. Medications: Especially sulfa antibiotics. Surgical removal of the third eyelid gland: Known as “cherry eye.” Autoimmune disease: The most common cause, where the immune system attacks the lacrimal gland, reducing tear production. Certain breeds are predisposed to dry eye, including Cocker Spaniels, Shih Tzus, Lhasa Apsos, Bulldogs, Schnauzers, and West Highland White Terriers. Signs of Dry Eye If your pet has dry eye, you may notice: Heavy mucus or discharge. Redness in the eyes. Rubbing or pawing at the eyes. Cloudy appearance in the eyes. Corneal ulcers. General lethargy or discomfort. Without treatment, prolonged dryness can lead to scar tissue and blood vessel growth on the cornea, potentially causing blindness. Many dogs with dry eye have a history of being treated repeatedly for “conjunctivitis” without realizing the underlying cause. Treatment Goals Managing dry eye focuses on: Stimulating Tear Production: Medications like Cyclosporine or Tacrolimus reduce immune system attacks on the lacrimal gland and help restore natural tear production. Lubricating the Eyes: Keeping the eyes moisturized to reduce discomfort. Reducing Scar Tissue: Preserving your pet’s vision. It’s important to understand that dry eye requires ongoing management. Missing doses of medication or running out can quickly lead to a recurrence of symptoms. How We Can Help At Animal Eye Services, we’ll create a tailored treatment plan for your pet, monitor their progress, and ensure their eyes stay as healthy and comfortable as possible. If you suspect your pet has dry eye, schedule a consultation today to prevent further discomfort and protect their vision.
  • Prolapsed Gland of the Third Eyelid 'Cherry Eye'
    Understanding Cherry Eye in Dogs Cherry eye occurs when the tear gland of the third eyelid slips out of its normal position, creating a visible reddish mass in your dog’s eye. While it might look alarming, cherry eye itself is rarely painful. However, prompt treatment is essential to prevent irritation, infection, or long-term complications. At Animal Eye Services, we’re here to help you understand cherry eye, its effects, and how it can be treated to protect your dog’s eye health. What Is Cherry Eye? The third eyelid contains a tear gland that helps maintain normal tear production. When this gland prolapses, or pops out of position, it becomes visible as a red, swollen mass near the corner of your dog’s eye. Cherry eye is most common in young dogs and certain breeds, including: Cocker Spaniels Lhasa Apsos Shih Tzus Poodles Bulldogs Why Treatment Is Important Although cherry eye may not cause immediate pain, leaving it untreated can lead to: Irritation or Inflammation: Prolonged exposure increases the risk of swelling and discomfort. Bleeding or Infection: If your dog rubs at their eye, the gland may bleed or become infected. Tear Gland Dysfunction: Long-term exposure can impair the gland’s ability to produce tears, increasing the risk of developing Dry Eye Syndrome later in life. How Is Cherry Eye Treated? The best treatment for cherry eye is surgical replacement of the tear gland, a procedure that preserves its function. Removing the gland, an outdated approach, is no longer recommended because it increases the risk of Dry Eye Syndrome—a chronic condition that requires lifelong medication. The Pocket Technique The preferred surgical method is called the pocket technique, which involves: Creating a small pocket on the back surface of the third eyelid. Gently tucking the tear gland into the pocket. Suturing the pocket closed to secure the gland in its proper position. In some cases, dogs may have underlying cartilage abnormalities in the third eyelid, making it challenging to achieve a completely normal appearance after surgery. However, the focus remains on preserving the gland’s function to maintain long-term eye health. How We Can Help At Animal Eye Services, we specialise in diagnosing and treating conditions like cherry eye to protect your pet’s vision and comfort. If you suspect cherry eye in your dog, contact us for a consultation. Early intervention ensures the best outcome for your pet’s health and happiness.
  • Distichiasis
    Understanding Distichiasis in Dogs Distichiasis is a condition where abnormal eyelashes grow from the meibomian glands in the eyelids. These glands are not meant to produce hairs, and when they do, the extra eyelashes can rub against the eye, causing irritation and discomfort. At Animal Eye Services, we’re here to help you understand distichiasis, its symptoms, and how it can be managed to ensure your pet’s comfort and eye health. What Causes Distichiasis? Distichiasis often runs in genetic lines and is most commonly seen in breeds such as: Staffordshire Bull Terriers American Cocker Spaniels Shih Tzus Tibetan Spaniels Poodles Signs of Distichiasis If your dog has distichiasis, you may notice: Redness in the eyes Squinting or sensitivity to light Discharge from the eyes Rubbing or pawing at the eyes In some cases, the abnormal hairs can lead to more serious issues like corneal ulcers or erosions, where the hairs damage the surface of the eye. Diagnosing and Treating Distichiasis The severity of distichiasis varies from dog to dog: Mild Cases: Some pets live comfortably with minimal or no symptoms. Moderate to Severe Cases: Pets experiencing persistent irritation or ulcers may require treatment. Temporary Relief Abnormal hairs can be plucked during an exam to provide short-term relief, but these lashes typically grow back. Topical ointments may be used to lubricate and protect the eye. Cryosurgery for Long-Term Management If symptoms persist, cryosurgery is an effective treatment option. This procedure uses a liquid nitrogen or nitrous oxide probe to freeze and destroy the hair-producing cells in the affected glands. Benefits: Prevents regrowth of the treated hairs. Considerations: With approximately 60 glands along each eyelid, new abnormal hairs can potentially emerge in untreated areas. While cryosurgery addresses the immediate problem, follow-up may be needed if new distichia develop. How We Can Help At Animal Eye Services, we tailor our approach to meet the unique needs of each pet. Whether your dog requires medical management, cryosurgery, or ongoing monitoring, we’re here to ensure they receive the best care possible. If your dog is showing signs of eye irritation, contact us to schedule a consultation. Early intervention can make a big difference in protecting your pet’s comfort and vision.
  • Entropion
    Understanding Entropion in Dogs Entropion is a condition where the eyelid rolls inward, causing the eyelashes and outer lid to rub against the eye's surface. This can lead to discomfort, irritation, and in some cases, more severe damage like corneal ulcers. At Animal Eye Services, we’re here to help you understand entropion, its impact on your pet, and how surgical correction can restore their comfort and vision. What Causes Entropion? Entropion is most commonly seen in breeds with specific head and facial conformation, including: Shar Peis Chow Chows Bulldogs Retrievers Rottweilers Mastiffs Although the exact genetic cause isn’t always known, entropion is believed to be influenced by multiple genes. For this reason, dogs affected by entropion should not be bred, as the condition can be passed to their offspring. Signs of Entropion If your dog has entropion, you may notice: Squinting: A sign of eye discomfort. Excessive tearing: Due to irritation. Rubbing at the eyes: Attempting to relieve discomfort. In severe cases, entropion can cause corneal ulcers, further compromising your dog’s eye health. Treatment for Entropion The best solution for entropion is surgical correction, which involves: Removing a small amount of skin and muscle along the eyelid margin. Reshaping the eyelid to prevent it from rolling inward. Closing the incision with tiny absorbable sutures, leaving no visible scar. This procedure not only improves your dog’s comfort but also restores the eyelid’s normal appearance. Timing of Surgery Permanent surgery is typically performed after the dog reaches 10 months of age, once growth has stabilized. In rare cases, additional surgery may be needed as your dog matures, but 95% of patients require only one procedure. What to Know After Surgery Following surgery, your dog should no longer experience discomfort or irritation. However, because entropion is considered a genetic condition, dogs who have had surgery should not be shown or bred. How We Can Help At Animal Eye Services, our experienced team specialises in diagnosing and correcting entropion to ensure your pet’s comfort and long-term eye health. If you suspect your dog has entropion, schedule a consultation today to discuss the best path forward.
  • Disorders in Brachycephalic Dogs
    Eye Problems in Flat-Nosed Dogs Flat-nosed breeds like Pugs, Pekingese, and Shih Tzus are prone to various eye conditions due to their unique facial structure. Their eyes sit prominently on the skull without the deep protective bony socket seen in other breeds. This conformation increases the risk of eye irritation, injury, and disease. At Animal Eye Services, we’re here to help you understand these challenges and provide solutions to protect your pet’s eye health. Common Eye Problems in Flat-Nosed Dogs Medial Lower Eyelid Entropion The inward rolling of the lower eyelid causes hairs to rub against the cornea. This leads to chronic irritation and the development of a pigmented film over the cornea. Oversized Eyelid Circumference Flat-nosed dogs often have larger eyelid openings compared to their cornea size. This increases the risk of globe proptosis (prolapse of the eyeball), a traumatic condition where the eyeball is forced out of the socket, potentially causing muscle damage or tearing of the optic nerve and leading to permanent blindness. Incomplete Eyelid Closure Many flat-nosed dogs cannot fully close their eyelids, especially during sleep. This exposes the cornea to dryness and secondary corneal diseases. How We Can Help The best way to prevent long-term eye problems in flat-nosed breeds is through a surgical procedure called permanent medial canthorrhaphy. What Is a Permanent Medial Canthorrhaphy? This procedure addresses multiple issues by: Removing a small section of the upper and lower eyelids at the inner corner of the eyes. Suturing the eyelids together to: Reduce the eyelid margin circumference. Correct medial lower eyelid entropion. The result is a more protected and stable eye, reducing the risk of irritation, injury, and complications associated with brachycephalic conformation. Protecting Your Pet’s Vision Flat-nosed dogs bring joy and companionship, but their unique facial structure requires extra care to maintain their eye health. At Animal Eye Services, we specialise in diagnosing and treating these issues to ensure your pet stays comfortable and healthy. If you have a flat-nosed dog showing signs of eye discomfort, or you’d like to discuss preventative care, contact us to schedule a consultation. Together, we can safeguard your pet’s vision and quality of life.
  • Hypertensive Retinopathy in Old Cats
    Understanding Hypertensive Retinopathy in Cats Hypertensive retinopathy is a serious condition where high blood pressure (hypertension) leads to retinal detachments or retinal hemorrhages, often causing sudden blindness. This condition is most commonly seen in elderly cats and requires prompt attention to address both the eye and underlying health issues. At Animal Eye Services, we’re here to guide you through understanding and managing this condition to give your pet the best chance for a healthy outcome. What Is Hypertensive Retinopathy? The retina is a delicate structure at the back of the eye responsible for detecting light and sending visual signals to the brain. Normally, it lies flat against the eye's interior. In hypertensive retinopathy: Retinal Detachment: High blood pressure causes the retina to separate from its normal position, leading to sudden blindness. Retinal Hemorrhages: Bleeding from small blood vessels in the retina can further impair vision. If diagnosed quickly, reattaching the retina may restore vision. However, because feline retinas degenerate rapidly, the prognosis for vision is often poor if treatment is delayed. Causes of Hypertension in Pets Unlike humans, high blood pressure in cats and dogs isn’t caused by diet. Instead, hypertension is usually secondary to other health conditions, such as: Kidney disease Heart disease Cushing’s disease Thyroid disease Signs of Hypertensive Retinopathy If your cat shows any of the following signs, seek veterinary attention immediately: Sudden blindness or loss of vision Behavioral changes, such as bumping into objects Dilated pupils or abnormal eye appearance Treatment for Hypertensive Retinopathy Managing hypertensive retinopathy focuses on two key goals: Controlling Hypertension: Medications are used to lower blood pressure and reduce further damage. Addressing Underlying Conditions: A thorough investigation will identify and manage the disease causing your pet’s high blood pressure. While retinal reattachment is sometimes possible, the speed of intervention is critical to preserving vision. How We Can Help At Animal Eye Services, we specialise in diagnosing and managing eye conditions like hypertensive retinopathy. We also work closely with your primary veterinarian to address underlying health issues contributing to hypertension. If you notice sudden changes in your cat’s vision or suspect high blood pressure, contact us immediately. Together, we can provide the care your pet needs to improve their comfort and quality of life.
  • Corneal Endothelial Disease
    Understanding Corneal Endothelial Disease in Dogs Corneal endothelial disease is a condition where excess fluid (oedema) accumulates in the cornea, leading to discomfort, vision impairment, and potentially painful ulcers. Understanding the anatomy and function of the cornea can help explain why this happens and how it affects your dog. At Animal Eye Services, we’re here to guide you through this complex condition and provide tailored solutions for your pet’s eye health. The Cornea: A Quick Overview The cornea has three main layers, each playing a crucial role in maintaining clarity and vision: Epithelium: The outer protective layer, making up 10% of corneal thickness. Stroma: The middle layer, the thickest part of the cornea, composed of collagen and osmotically active substances that regulate water content. Endothelium: The innermost layer, a single layer of hexagonal cells with pumps that move excess water out of the stroma. Unlike other layers, endothelial cells cannot regenerate. Once damaged or reduced below a critical density, they lose their ability to remove water, leading to corneal oedema and opacity. Signs and Effects of Corneal Endothelial Disease As the endothelium loses function, water accumulates in the cornea, causing: A bluish-white opacity. Light distortion and vision impairment. Chronic superficial ulcers if the fluid breaks through the outer epithelium, leading to pain and discomfort. Causes of Corneal Endothelial Disease The disease can develop due to: Age-related degeneration: Natural loss of endothelial cells over time. Breed predisposition: Breeds like Boston Terriers, Chihuahuas, and Springer Spaniels are more prone to early-onset endothelial dysfunction. Inflammation: Damage from inflammatory cells or proteins inside the eye. Glaucoma: High pressure inside the eye damaging the endothelial cells. Treatment Options Corneal endothelial disease is challenging to treat as damaged endothelial cells cannot be replaced. While emerging techniques like endothelial grafts are being explored, they are not yet widely available. Current management focuses on: Stabilising with Medication Drugs may reduce oedema and slow disease progression, though they cannot restore normal endothelial function. Advanced Procedures for Severe Cases Thermal Keratoplasty: Tiny burns are applied to the stroma to create scars that reduce water retention. Gundersen Flap: A thin conjunctival layer is grafted onto the cornea to help remove excess water via its blood vessels. While these procedures can improve comfort and functionality, they do not restore the cornea to full clarity. How We Can Help At Animal Eye Services, our veterinary ophthalmologists specialize in diagnosing and managing complex conditions like corneal endothelial disease. We’ll assess your dog’s specific case and discuss the best options to preserve their comfort and vision. If your dog is showing signs of corneal opacity or discomfort, contact us for a consultation. Early intervention can make a meaningful difference in managing this condition.
  • SCCED (Spontaneous Chronical Corneal Endothelial Defects)
    Understanding SCCEDs (Indolent Ulcers) in Dogs SCCEDs, also known as indolent ulcers, Boxer ulcers, or non-healing ulcers, are superficial defects in the outer layer of the cornea (epithelium) that fail to heal properly. This frustrating and recurring condition can cause discomfort and prolonged healing issues in affected dogs. At Animal Eye Services, we’re here to help you understand SCCEDs and discuss the best treatment options to restore your pet’s comfort and eye health. What Are SCCEDs? The cornea has a thin outer layer called the epithelium, which sits on a membrane called the basement membrane. Normally, the epithelium regenerates quickly, with basal cells sliding across the basement membrane and firmly adhering to repair any superficial damage. In dogs with SCCEDs, this adhesion process is disrupted due to a microscopic defect, preventing the ulcer from healing properly. Commonly Affected Breeds While SCCEDs can occur in any dog, certain breeds are predisposed, including: Boxers Samoyeds Welsh Corgis Staffordshire Bull Terriers Signs and Symptoms Dogs with SCCEDs may show: Persistent or recurring corneal ulcers. Discomfort or squinting. Tearing or discharge. Sensitivity to light. If untreated, these ulcers can persist for weeks or even months, sometimes appearing to heal only to recur. Why Don’t SCCEDs Heal Normally? The issue lies at a microscopic level: The epithelium fails to adhere to the basement membrane. Antibiotic ointments alone are ineffective because the condition isn’t caused by bacterial infection. Traditional treatments like eyelid flaps or simple debridement often don’t resolve the problem. Treatment Options To promote healing, the basement membrane must be altered to encourage epithelial adhesion. Depending on your dog’s condition, treatment options include: Basement Membrane Burring A simple outpatient procedure that mechanically disrupts the basement membrane to encourage healing. Grid Keratotomy A more involved procedure under general anesthesia, where small scratches are made in the cornea to help the epithelium adhere. Superficial Keratectomy A surgical procedure to remove the defective epithelial and basement membrane layer, allowing healthy tissue to regenerate. The goal of treatment is to achieve rapid healing and reduce the risk of recurrence. How We Can Help At Animal Eye Services, we understand how frustrating SCCEDs can be for both you and your dog. Our team will work with you to determine the best treatment plan to resolve this condition and restore your pet’s eye health. If your dog is showing signs of a non-healing ulcer, contact us today to schedule a consultation. Prompt intervention can make a significant difference in managing this condition effectively.

  • Cataracts in Dogs
  • Progressive Retinal Atrophy
    Understanding Progressive Retinal Atrophy (PRA) Progressive Retinal Atrophy (PRA) is a group of inherited diseases that gradually cause vision loss in dogs due to the degeneration of the retina. This condition is more common in certain breeds, including Cocker Spaniels, Poodles, Australian Cattle Dogs, Silky Terriers, and Labradors. Our goal is to help you understand PRA so you can make informed decisions for your pet and provide the best possible care during this journey. Signs and Symptoms PRA progresses slowly, with vision loss occurring over months or years: Early signs: Difficulty seeing in dim light (night vision), reluctance to go outside at night, or bumping into objects in low light. Owners may also notice an increased green reflection in their pet's eyes under artificial light. Later stages: Gradual loss of day vision and the development of cataracts (visible as white opacities in the pupil). Cataracts worsen vision loss by blocking light from reaching the retina. Unfortunately, because the vision loss is so gradual, many owners don’t notice a problem until the blindness is severe. Diagnosis Early detection is crucial. PRA can be diagnosed using: A thorough clinical eye examination. Chromatic PLR (Pupillary Light Reflex) testing. Electroretinogram (ERG) to assess retinal function. Treatment At this time, there is no treatment to reverse or halt PRA. However, management focuses on preventing complications associated with cataracts, such as: Uveitis (inflammation of the iris): Treated with cortisone drops to prevent further issues. Glaucoma (high pressure in the eye): Early treatment can help reduce discomfort and maintain eye health. While cataract removal is an option for other conditions, it is not effective for restoring vision in dogs with PRA. Prevention and Genetic Testing Because PRA is an inherited condition, understanding your dog’s genetics is vital: If PRA is identified, related dogs should be examined for the condition. PRA is typically inherited as an autosomal recessive trait, meaning both parents must carry the gene for it to be passed on. DNA blood tests are available to identify affected dogs and carriers, helping breeders make informed decisions to reduce the spread of PRA in future generations.

  • Lens Luxation
    Understanding Lens Luxation in Dogs Lens luxation occurs when the lens, which is normally held in place behind the iris and pupil by tiny fibers called zonules, moves out of its proper position. This condition can cause significant discomfort and vision problems, requiring prompt attention and treatment. At Animal Eye Services, we’re here to help you understand lens luxation, its causes, and the treatment options available to support your pet’s eye health. What Is Lens Luxation? There are two types of lens luxation: Subluxation: The lens is partially displaced but still held in place by some zonules. Complete Luxation: The lens is entirely displaced because all the zonules have broken. Causes of Lens Luxation Lens luxation can be classified into two categories based on the cause: Primary Lens Luxation: Commonly seen in breeds such as Jack Russell Terriers, Miniature Fox Terriers, Tenterfield Terriers, and Cattle Dogs. Caused by genetic defects that weaken the zonules over time. Trauma can also cause lens luxation, though it’s rarely the sole cause. Secondary Lens Luxation: Occurs as a result of other eye conditions, such as: Glaucoma: Elevated pressure inside the eye weakens the zonules. Uveitis: Inflammation inside the eye damages the zonules. A luxated lens can also lead to secondary complications, including glaucoma. Signs of Lens Luxation If your dog has lens luxation, you may notice: Sudden vision loss. Pain or discomfort in the eye. Redness or swelling. A visible shift in the lens position. Treatment Options Treatment depends on the severity of the condition, the position of the lens, and the overall health of the eye: Medications: If the lens is loose but still behind the iris, special prescription drops can constrict the pupil and hold the lens in place. These drops must be used for life, as missing a dose can cause the lens to slip back into the front chamber. Surgical Intervention: Lens Removal (Lensectomy): Performed under general anesthesia using an operating microscope. The lens is removed through a small incision in the eye using specialized tools. While up-close vision may be fuzzy without a lens, most dogs maintain good general vision. Lens Repositioning: In some cases, the lens can be carefully moved back behind the iris and stabilized with medication. Risks and Prognosis Unfortunately, even with prompt treatment, some eyes affected by lens luxation may become blind or require removal due to uncontrollable pain. Early intervention and proper management can improve the chances of preserving vision and comfort. How We Can Help At Animal Eye Services, we specialise in diagnosing and treating complex eye conditions like lens luxation. If you notice signs of vision changes or discomfort in your dog, contact us immediately. Our team is here to guide you through the best treatment options and provide compassionate care for your pet.
  • Glaucoma
    Understanding Glaucoma in Pets Glaucoma is a serious eye condition caused by an increase in pressure inside the eye, often leading to vision loss and significant pain. This is a true ophthalmic emergency—prompt treatment is critical to preserving your pet’s comfort and vision. At Animal Eye Services, we understand how alarming glaucoma can be. We’re here to help you recognize the signs, understand the condition, and navigate the treatment options. Signs of Glaucoma Glaucoma can manifest through a range of symptoms. If you notice any of the following, seek veterinary care immediately: Redness in the eye A cloudy appearance in the eye Tearing or excessive discharge Vision loss An enlarged eyeball Unusual aggression or irritability Lethargy or lack of energy Loss of appetite What Causes Glaucoma? Glaucoma occurs when the eye's fluid (produced behind the pupil in the ciliary body) cannot drain properly through the natural pathway between the cornea and iris. This leads to a dangerous buildup of pressure. Think of it like a kitchen sink: if the drain is clear, water flows through without issue. But if the drain is blocked and water keeps running, the sink overflows. Similarly, when the fluid in the eye can't drain, pressure builds up, causing damage to the eye structures. Types of Glaucoma: Primary Glaucoma: Occurs without any underlying disease. Secondary Glaucoma: Caused by conditions like inflammation, trauma, or tumors that obstruct fluid drainage. Why Prompt Treatment Matters Glaucoma is an emergency. If the pressure in the eye remains elevated for even a few hours, permanent vision loss can occur. Early detection and immediate intervention are key to minimizing damage and relieving your pet’s pain. Treatment Options Treatment depends on the severity of the glaucoma, whether vision can still be preserved, and factors like your pet’s overall health and your family’s circumstances. Options may include: Medical Management: Medications to lower eye pressure. Laser Surgery: Helps reduce fluid production or improve drainage. Surgical Drainage Tubes: Implanted to assist with fluid outflow. Removal of a Blind, Painful Eye: Improves comfort when vision cannot be saved. Cosmetic Prosthesis: Provides an aesthetic solution if the eye needs removal. Each treatment has pros and cons, and the best course of action will be tailored to your pet's specific needs. During your consultation, we’ll discuss all options to help you make an informed decision. How We Can Help At Animal Eye Services, we’re here to support you through every step of diagnosis, treatment, and follow-up care. If you suspect glaucoma, contact us immediately—your pet’s comfort and vision depend on timely action.
  • Uveitis
    Understanding Uveitis in Pets Uveitis is a condition involving inflammation of the uveal tract, the part of the eye that contains blood vessels. This inflammation can cause discomfort, cloudiness, and even vision loss in severe cases. At Animal Eye Services, we’re here to help you understand this condition, its potential causes, and how it can be treated to protect your pet’s eye health. What Is the Uveal Tract? The uveal tract lines the inside of the eye and has three main parts: Iris: The colored part at the front of the eye. Ciliary Body: A specialized part that produces fluid inside the eye. Choroid: A structure under the retina at the back of the eye. Because the uveal tract contains blood vessels, inflammation can cause blood cells and debris to leak into the eye’s fluid-filled chambers, leading to visible changes and, in severe cases, vision loss. Signs of Uveitis If your pet has uveitis, you might notice: Cloudiness in the cornea. Redness around the edge of the eye. Excessive tearing or watery eyes. Squinting or sensitivity to light. Bleeding into the eye. Vision loss. Causes of Uveitis Uveitis can have a variety of underlying causes, which will be thoroughly assessed during your pet’s consultation. Common causes include infections, trauma, immune-mediated conditions, and other systemic diseases. Why Uveitis Needs Prompt Attention Severe uveitis can lead to serious complications that threaten your pet’s vision, including: Cataracts: Cloudiness of the lens. Adhesions: The iris sticking to the lens or cornea. Retinal Disease: Damage to the retina. Glaucoma: Increased pressure in the eye. Treatment for Uveitis Treatment focuses on: Reducing inflammation: Using medications to manage swelling and discomfort. Preventing complications: Protecting against long-term damage to the eye. Every pet’s treatment plan is tailored to their specific condition, based on the severity of the uveitis and its underlying cause. How We Can Help At Animal Eye Services, we’re committed to preserving your pet’s vision and comfort. If you notice any of the signs of uveitis, don’t delay—schedule a consultation so we can determine the best course of action for your pet’s care.
  • Dry Eye
    Understanding Dry Eye in Pets A healthy cornea and conjunctiva—the clear structures at the front of the eye—depend on a balanced and functioning tear film. When this tear film is disrupted, your pet may develop dry eye, a condition that causes discomfort, redness, and even vision loss if left untreated. At Animal Eye Services, we’re here to help you understand the causes, symptoms, and treatment options for dry eye, ensuring your pet’s comfort and eye health. What Is the Tear Film? The tear film is made up of three essential layers: Lipid Layer: The outermost layer, produced by Meibomian glands in the eyelids, prevents tear evaporation. Aqueous Layer: The watery middle layer makes up 95% of the tear film and is produced by the lacrimal gland behind the upper eyelid. Mucous Layer: The innermost layer helps the tear film adhere to the surface of the cornea. When one or more of these layers is compromised, the eye can’t stay properly hydrated, leading to dry eye. Causes of Dry Eye Dry eye has many potential causes, including: Congenital disorders: Common in puppies. Infections: Such as canine distemper virus. Medications: Especially sulfa antibiotics. Surgical removal of the third eyelid gland: Known as “cherry eye.” Autoimmune disease: The most common cause, where the immune system attacks the lacrimal gland, reducing tear production. Certain breeds are predisposed to dry eye, including Cocker Spaniels, Shih Tzus, Lhasa Apsos, Bulldogs, Schnauzers, and West Highland White Terriers. Signs of Dry Eye If your pet has dry eye, you may notice: Heavy mucus or discharge. Redness in the eyes. Rubbing or pawing at the eyes. Cloudy appearance in the eyes. Corneal ulcers. General lethargy or discomfort. Without treatment, prolonged dryness can lead to scar tissue and blood vessel growth on the cornea, potentially causing blindness. Many dogs with dry eye have a history of being treated repeatedly for “conjunctivitis” without realizing the underlying cause. Treatment Goals Managing dry eye focuses on: Stimulating Tear Production: Medications like Cyclosporine or Tacrolimus reduce immune system attacks on the lacrimal gland and help restore natural tear production. Lubricating the Eyes: Keeping the eyes moisturized to reduce discomfort. Reducing Scar Tissue: Preserving your pet’s vision. It’s important to understand that dry eye requires ongoing management. Missing doses of medication or running out can quickly lead to a recurrence of symptoms. How We Can Help At Animal Eye Services, we’ll create a tailored treatment plan for your pet, monitor their progress, and ensure their eyes stay as healthy and comfortable as possible. If you suspect your pet has dry eye, schedule a consultation today to prevent further discomfort and protect their vision.
  • Prolapsed Gland of the Third Eyelid 'Cherry Eye'
    Understanding Cherry Eye in Dogs Cherry eye occurs when the tear gland of the third eyelid slips out of its normal position, creating a visible reddish mass in your dog’s eye. While it might look alarming, cherry eye itself is rarely painful. However, prompt treatment is essential to prevent irritation, infection, or long-term complications. At Animal Eye Services, we’re here to help you understand cherry eye, its effects, and how it can be treated to protect your dog’s eye health. What Is Cherry Eye? The third eyelid contains a tear gland that helps maintain normal tear production. When this gland prolapses, or pops out of position, it becomes visible as a red, swollen mass near the corner of your dog’s eye. Cherry eye is most common in young dogs and certain breeds, including: Cocker Spaniels Lhasa Apsos Shih Tzus Poodles Bulldogs Why Treatment Is Important Although cherry eye may not cause immediate pain, leaving it untreated can lead to: Irritation or Inflammation: Prolonged exposure increases the risk of swelling and discomfort. Bleeding or Infection: If your dog rubs at their eye, the gland may bleed or become infected. Tear Gland Dysfunction: Long-term exposure can impair the gland’s ability to produce tears, increasing the risk of developing Dry Eye Syndrome later in life. How Is Cherry Eye Treated? The best treatment for cherry eye is surgical replacement of the tear gland, a procedure that preserves its function. Removing the gland, an outdated approach, is no longer recommended because it increases the risk of Dry Eye Syndrome—a chronic condition that requires lifelong medication. The Pocket Technique The preferred surgical method is called the pocket technique, which involves: Creating a small pocket on the back surface of the third eyelid. Gently tucking the tear gland into the pocket. Suturing the pocket closed to secure the gland in its proper position. In some cases, dogs may have underlying cartilage abnormalities in the third eyelid, making it challenging to achieve a completely normal appearance after surgery. However, the focus remains on preserving the gland’s function to maintain long-term eye health. How We Can Help At Animal Eye Services, we specialise in diagnosing and treating conditions like cherry eye to protect your pet’s vision and comfort. If you suspect cherry eye in your dog, contact us for a consultation. Early intervention ensures the best outcome for your pet’s health and happiness.
  • Distichiasis
    Understanding Distichiasis in Dogs Distichiasis is a condition where abnormal eyelashes grow from the meibomian glands in the eyelids. These glands are not meant to produce hairs, and when they do, the extra eyelashes can rub against the eye, causing irritation and discomfort. At Animal Eye Services, we’re here to help you understand distichiasis, its symptoms, and how it can be managed to ensure your pet’s comfort and eye health. What Causes Distichiasis? Distichiasis often runs in genetic lines and is most commonly seen in breeds such as: Staffordshire Bull Terriers American Cocker Spaniels Shih Tzus Tibetan Spaniels Poodles Signs of Distichiasis If your dog has distichiasis, you may notice: Redness in the eyes Squinting or sensitivity to light Discharge from the eyes Rubbing or pawing at the eyes In some cases, the abnormal hairs can lead to more serious issues like corneal ulcers or erosions, where the hairs damage the surface of the eye. Diagnosing and Treating Distichiasis The severity of distichiasis varies from dog to dog: Mild Cases: Some pets live comfortably with minimal or no symptoms. Moderate to Severe Cases: Pets experiencing persistent irritation or ulcers may require treatment. Temporary Relief Abnormal hairs can be plucked during an exam to provide short-term relief, but these lashes typically grow back. Topical ointments may be used to lubricate and protect the eye. Cryosurgery for Long-Term Management If symptoms persist, cryosurgery is an effective treatment option. This procedure uses a liquid nitrogen or nitrous oxide probe to freeze and destroy the hair-producing cells in the affected glands. Benefits: Prevents regrowth of the treated hairs. Considerations: With approximately 60 glands along each eyelid, new abnormal hairs can potentially emerge in untreated areas. While cryosurgery addresses the immediate problem, follow-up may be needed if new distichia develop. How We Can Help At Animal Eye Services, we tailor our approach to meet the unique needs of each pet. Whether your dog requires medical management, cryosurgery, or ongoing monitoring, we’re here to ensure they receive the best care possible. If your dog is showing signs of eye irritation, contact us to schedule a consultation. Early intervention can make a big difference in protecting your pet’s comfort and vision.
  • Entropion
    Understanding Entropion in Dogs Entropion is a condition where the eyelid rolls inward, causing the eyelashes and outer lid to rub against the eye's surface. This can lead to discomfort, irritation, and in some cases, more severe damage like corneal ulcers. At Animal Eye Services, we’re here to help you understand entropion, its impact on your pet, and how surgical correction can restore their comfort and vision. What Causes Entropion? Entropion is most commonly seen in breeds with specific head and facial conformation, including: Shar Peis Chow Chows Bulldogs Retrievers Rottweilers Mastiffs Although the exact genetic cause isn’t always known, entropion is believed to be influenced by multiple genes. For this reason, dogs affected by entropion should not be bred, as the condition can be passed to their offspring. Signs of Entropion If your dog has entropion, you may notice: Squinting: A sign of eye discomfort. Excessive tearing: Due to irritation. Rubbing at the eyes: Attempting to relieve discomfort. In severe cases, entropion can cause corneal ulcers, further compromising your dog’s eye health. Treatment for Entropion The best solution for entropion is surgical correction, which involves: Removing a small amount of skin and muscle along the eyelid margin. Reshaping the eyelid to prevent it from rolling inward. Closing the incision with tiny absorbable sutures, leaving no visible scar. This procedure not only improves your dog’s comfort but also restores the eyelid’s normal appearance. Timing of Surgery Permanent surgery is typically performed after the dog reaches 10 months of age, once growth has stabilized. In rare cases, additional surgery may be needed as your dog matures, but 95% of patients require only one procedure. What to Know After Surgery Following surgery, your dog should no longer experience discomfort or irritation. However, because entropion is considered a genetic condition, dogs who have had surgery should not be shown or bred. How We Can Help At Animal Eye Services, our experienced team specialises in diagnosing and correcting entropion to ensure your pet’s comfort and long-term eye health. If you suspect your dog has entropion, schedule a consultation today to discuss the best path forward.
  • Disorders in Brachycephalic Dogs
    Eye Problems in Flat-Nosed Dogs Flat-nosed breeds like Pugs, Pekingese, and Shih Tzus are prone to various eye conditions due to their unique facial structure. Their eyes sit prominently on the skull without the deep protective bony socket seen in other breeds. This conformation increases the risk of eye irritation, injury, and disease. At Animal Eye Services, we’re here to help you understand these challenges and provide solutions to protect your pet’s eye health. Common Eye Problems in Flat-Nosed Dogs Medial Lower Eyelid Entropion The inward rolling of the lower eyelid causes hairs to rub against the cornea. This leads to chronic irritation and the development of a pigmented film over the cornea. Oversized Eyelid Circumference Flat-nosed dogs often have larger eyelid openings compared to their cornea size. This increases the risk of globe proptosis (prolapse of the eyeball), a traumatic condition where the eyeball is forced out of the socket, potentially causing muscle damage or tearing of the optic nerve and leading to permanent blindness. Incomplete Eyelid Closure Many flat-nosed dogs cannot fully close their eyelids, especially during sleep. This exposes the cornea to dryness and secondary corneal diseases. How We Can Help The best way to prevent long-term eye problems in flat-nosed breeds is through a surgical procedure called permanent medial canthorrhaphy. What Is a Permanent Medial Canthorrhaphy? This procedure addresses multiple issues by: Removing a small section of the upper and lower eyelids at the inner corner of the eyes. Suturing the eyelids together to: Reduce the eyelid margin circumference. Correct medial lower eyelid entropion. The result is a more protected and stable eye, reducing the risk of irritation, injury, and complications associated with brachycephalic conformation. Protecting Your Pet’s Vision Flat-nosed dogs bring joy and companionship, but their unique facial structure requires extra care to maintain their eye health. At Animal Eye Services, we specialise in diagnosing and treating these issues to ensure your pet stays comfortable and healthy. If you have a flat-nosed dog showing signs of eye discomfort, or you’d like to discuss preventative care, contact us to schedule a consultation. Together, we can safeguard your pet’s vision and quality of life.
  • Hypertensive Retinopathy in Old Cats
    Understanding Hypertensive Retinopathy in Cats Hypertensive retinopathy is a serious condition where high blood pressure (hypertension) leads to retinal detachments or retinal hemorrhages, often causing sudden blindness. This condition is most commonly seen in elderly cats and requires prompt attention to address both the eye and underlying health issues. At Animal Eye Services, we’re here to guide you through understanding and managing this condition to give your pet the best chance for a healthy outcome. What Is Hypertensive Retinopathy? The retina is a delicate structure at the back of the eye responsible for detecting light and sending visual signals to the brain. Normally, it lies flat against the eye's interior. In hypertensive retinopathy: Retinal Detachment: High blood pressure causes the retina to separate from its normal position, leading to sudden blindness. Retinal Hemorrhages: Bleeding from small blood vessels in the retina can further impair vision. If diagnosed quickly, reattaching the retina may restore vision. However, because feline retinas degenerate rapidly, the prognosis for vision is often poor if treatment is delayed. Causes of Hypertension in Pets Unlike humans, high blood pressure in cats and dogs isn’t caused by diet. Instead, hypertension is usually secondary to other health conditions, such as: Kidney disease Heart disease Cushing’s disease Thyroid disease Signs of Hypertensive Retinopathy If your cat shows any of the following signs, seek veterinary attention immediately: Sudden blindness or loss of vision Behavioral changes, such as bumping into objects Dilated pupils or abnormal eye appearance Treatment for Hypertensive Retinopathy Managing hypertensive retinopathy focuses on two key goals: Controlling Hypertension: Medications are used to lower blood pressure and reduce further damage. Addressing Underlying Conditions: A thorough investigation will identify and manage the disease causing your pet’s high blood pressure. While retinal reattachment is sometimes possible, the speed of intervention is critical to preserving vision. How We Can Help At Animal Eye Services, we specialise in diagnosing and managing eye conditions like hypertensive retinopathy. We also work closely with your primary veterinarian to address underlying health issues contributing to hypertension. If you notice sudden changes in your cat’s vision or suspect high blood pressure, contact us immediately. Together, we can provide the care your pet needs to improve their comfort and quality of life.
  • Corneal Endothelial Disease
    Understanding Corneal Endothelial Disease in Dogs Corneal endothelial disease is a condition where excess fluid (oedema) accumulates in the cornea, leading to discomfort, vision impairment, and potentially painful ulcers. Understanding the anatomy and function of the cornea can help explain why this happens and how it affects your dog. At Animal Eye Services, we’re here to guide you through this complex condition and provide tailored solutions for your pet’s eye health. The Cornea: A Quick Overview The cornea has three main layers, each playing a crucial role in maintaining clarity and vision: Epithelium: The outer protective layer, making up 10% of corneal thickness. Stroma: The middle layer, the thickest part of the cornea, composed of collagen and osmotically active substances that regulate water content. Endothelium: The innermost layer, a single layer of hexagonal cells with pumps that move excess water out of the stroma. Unlike other layers, endothelial cells cannot regenerate. Once damaged or reduced below a critical density, they lose their ability to remove water, leading to corneal oedema and opacity. Signs and Effects of Corneal Endothelial Disease As the endothelium loses function, water accumulates in the cornea, causing: A bluish-white opacity. Light distortion and vision impairment. Chronic superficial ulcers if the fluid breaks through the outer epithelium, leading to pain and discomfort. Causes of Corneal Endothelial Disease The disease can develop due to: Age-related degeneration: Natural loss of endothelial cells over time. Breed predisposition: Breeds like Boston Terriers, Chihuahuas, and Springer Spaniels are more prone to early-onset endothelial dysfunction. Inflammation: Damage from inflammatory cells or proteins inside the eye. Glaucoma: High pressure inside the eye damaging the endothelial cells. Treatment Options Corneal endothelial disease is challenging to treat as damaged endothelial cells cannot be replaced. While emerging techniques like endothelial grafts are being explored, they are not yet widely available. Current management focuses on: Stabilising with Medication Drugs may reduce oedema and slow disease progression, though they cannot restore normal endothelial function. Advanced Procedures for Severe Cases Thermal Keratoplasty: Tiny burns are applied to the stroma to create scars that reduce water retention. Gundersen Flap: A thin conjunctival layer is grafted onto the cornea to help remove excess water via its blood vessels. While these procedures can improve comfort and functionality, they do not restore the cornea to full clarity. How We Can Help At Animal Eye Services, our veterinary ophthalmologists specialize in diagnosing and managing complex conditions like corneal endothelial disease. We’ll assess your dog’s specific case and discuss the best options to preserve their comfort and vision. If your dog is showing signs of corneal opacity or discomfort, contact us for a consultation. Early intervention can make a meaningful difference in managing this condition.
  • SCCED (Spontaneous Chronical Corneal Endothelial Defects)
    Understanding SCCEDs (Indolent Ulcers) in Dogs SCCEDs, also known as indolent ulcers, Boxer ulcers, or non-healing ulcers, are superficial defects in the outer layer of the cornea (epithelium) that fail to heal properly. This frustrating and recurring condition can cause discomfort and prolonged healing issues in affected dogs. At Animal Eye Services, we’re here to help you understand SCCEDs and discuss the best treatment options to restore your pet’s comfort and eye health. What Are SCCEDs? The cornea has a thin outer layer called the epithelium, which sits on a membrane called the basement membrane. Normally, the epithelium regenerates quickly, with basal cells sliding across the basement membrane and firmly adhering to repair any superficial damage. In dogs with SCCEDs, this adhesion process is disrupted due to a microscopic defect, preventing the ulcer from healing properly. Commonly Affected Breeds While SCCEDs can occur in any dog, certain breeds are predisposed, including: Boxers Samoyeds Welsh Corgis Staffordshire Bull Terriers Signs and Symptoms Dogs with SCCEDs may show: Persistent or recurring corneal ulcers. Discomfort or squinting. Tearing or discharge. Sensitivity to light. If untreated, these ulcers can persist for weeks or even months, sometimes appearing to heal only to recur. Why Don’t SCCEDs Heal Normally? The issue lies at a microscopic level: The epithelium fails to adhere to the basement membrane. Antibiotic ointments alone are ineffective because the condition isn’t caused by bacterial infection. Traditional treatments like eyelid flaps or simple debridement often don’t resolve the problem. Treatment Options To promote healing, the basement membrane must be altered to encourage epithelial adhesion. Depending on your dog’s condition, treatment options include: Basement Membrane Burring A simple outpatient procedure that mechanically disrupts the basement membrane to encourage healing. Grid Keratotomy A more involved procedure under general anesthesia, where small scratches are made in the cornea to help the epithelium adhere. Superficial Keratectomy A surgical procedure to remove the defective epithelial and basement membrane layer, allowing healthy tissue to regenerate. The goal of treatment is to achieve rapid healing and reduce the risk of recurrence. How We Can Help At Animal Eye Services, we understand how frustrating SCCEDs can be for both you and your dog. Our team will work with you to determine the best treatment plan to resolve this condition and restore your pet’s eye health. If your dog is showing signs of a non-healing ulcer, contact us today to schedule a consultation. Prompt intervention can make a significant difference in managing this condition effectively.
