Understanding Corneal Ulcers
When it comes to the eye health of cats, corneal ulcers can be a cause for concern. Understanding the causes and symptoms of corneal ulcers is essential for early detection and proper treatment.
Causes of Corneal Ulcers
Cat corneal ulcers are most commonly caused by trauma to the eye, which can be blunt (from rubbing against a rough surface) or sharp (from objects like thorns or claws). Other causes include chemical burns, infections, and foreign objects trapped under the eyelid (WebMD). Feline corneal ulcers can also be a result of scratches, ingrown eyelashes, dirt trapped beneath the eyelid, exposure to caustic chemicals, and viral or bacterial infections. The most frequent cause is recurrent infection with the feline herpesvirus (FHV), which can lead to ulceration on the surface of the eye.
Symptoms of Corneal Ulcers
Detecting the symptoms of cat corneal ulcers is crucial for prompt diagnosis and treatment. Some common symptoms to look out for include:
- Eye inflammation
- Weepy eye
- Painful eye (squinting or rubbing)
- Cloudy eye
- Hypersensitivity to light
- Depressed eye
It’s important to note that some ulcers may be asymptomatic, making regular eye examinations by a veterinarian essential for early detection and intervention. Clinical signs of corneal ulceration in cats may also include inflammation of the tissue surrounding the cornea, seepage of discharge from the eye, clouding of the cornea, and apparent hypersensitivity to bright light. Affected cats may squint, rub their eyes, and exhibit behavior indicating vision problems.

Diagnosis and Treatment
When it comes to the diagnosis and treatment of corneal ulcers in cats, prompt evaluation and appropriate management are crucial for the well-being of your feline companion.
Diagnostic Procedures
Diagnosing corneal ulcers in cats involves a comprehensive examination of the affected eye, coupled with a review of the animal’s medical history. A tentative diagnosis can be confirmed through a diagnostic test using fluorescein eye drops. This dye binds to damaged tissue, causing the ulcerated area to appear greenish in color.
Treatment Options
The treatment of corneal ulcers in cats primarily focuses on reducing pain, controlling inflammation, and preventing bacterial or fungal infections. The specific treatment options may vary depending on the severity and nature of the ulcer.
In most cases, veterinary professionals prescribe a combination of medication to manage corneal ulcers in cats. These medications commonly include:
- Lubricating Eye Drops: These provide moisture and help protect the cornea during the healing process.
- Antibiotic Eye Drops: These are used to prevent or treat bacterial infections that may arise due to the presence of the ulcer.
- Anti-inflammatory Pain Relief Medications: These medications help alleviate pain and reduce inflammation associated with corneal ulcers.
It’s important to follow the prescribed medication regimen and administer the drops or ointments as instructed by your veterinarian. This ensures optimal healing and minimizes the risk of complications.
In some cases, if the ulcer does not respond to medical treatment or if the ulcer is deep or complicated, surgical intervention may be necessary. Surgical options for corneal ulcers in cats may include:
- Suturing the Third Eyelid: This technique involves suturing the third eyelid over the ulcer to protect and promote healing.
- Keratectomy: In this procedure, dead corneal tissue is removed to facilitate the healing process.
Surgery is typically reserved for severe cases or when medical treatment fails to yield satisfactory results. Your veterinarian will assess the specific needs of your cat and recommend the most appropriate course of action.
It’s important to closely monitor your cat’s progress during the treatment phase. Regular follow-up examinations with your veterinarian are recommended to ensure proper healing progress and to address any complications that may arise.
By promptly diagnosing corneal ulcers and implementing appropriate treatment measures, you can help restore your cat’s vision and improve their overall ocular health.
Recovery and Post-Surgery Care
After undergoing corneal ulcer surgery, proper recovery and post-surgery care are crucial for the overall healing and well-being of the cat. This section will provide information on post-operative instructions and medications for pain management.
Post-Operative Instructions
Following surgery, it is normal for cats to experience temporary sleepiness and shakiness on their feet due to the effects of general anesthesia. Additionally, a temporary lack of appetite may occur. These effects should fade with rest.
To ensure a smooth recovery, it is important to provide a quiet, stress-free environment for the cat. Limiting their movement, especially after orthopedic surgery, is crucial for proper healing. Crate rest may be recommended in some cases. Providing a comfortable bed for the cat will help promote rest and relaxation during the recovery period (Carolina Veterinary Specialists).
In addition, it is essential to closely monitor the cat’s eating habits post-surgery. While a temporary lack of appetite is common, if the cat is not eating after 48 hours, it is important to contact the veterinarian. This could indicate infection or pain, and the veterinarian can provide guidance on next steps (Carolina Veterinary Specialists).
Medications and Pain Management
To aid in the recovery process and prevent infections, veterinarians often prescribe antibiotics after corneal ulcer surgery. These medications help protect against potential complications and promote healing. Additionally, pain medications may be prescribed to alleviate any discomfort or pain associated with the surgery.
It is important to follow the veterinarian’s instructions regarding medication administration and dosage. If there are any concerns or questions about the prescribed medications, it is advisable to reach out to the veterinarian for clarification or guidance.
For cats that may be anxious or stressed during the healing process, sedatives or anti-anxiety medications may also be prescribed to promote calmness and reduce stress. These medications can aid in the overall recovery of the cat.
Proper pain management and medication administration are crucial for the comfort and well-being of the cat. Adhering to the prescribed medication schedule and dosage will help facilitate a smoother recovery and ensure the cat’s overall well-being.
Remember, each cat’s recovery process may vary, and it is important to closely follow the veterinarian’s instructions and guidance specific to your cat’s needs. Regular post-operative check-ups with the veterinarian may also be necessary to monitor the healing progress and make any necessary adjustments to the recovery plan.
Preventing Corneal Ulcers
Taking proactive measures to prevent corneal ulcers in cats is essential for maintaining their ocular health. By understanding the risk factors and implementing preventive measures, you can help protect your feline companion from this painful condition.
Risk Factors
Corneal ulcers in cats can have various causes, including scratches, ingrown eyelashes, exposure to caustic chemicals, and viral or bacterial infections. One of the most common causes is recurrent infection with the feline herpesvirus (FHV), which can lead to ulceration on the surface of the eye (Cornell Feline Health Center). Some of the risk factors associated with corneal ulcers in cats are:
- Trauma to the eye: Removing objects that can cause trauma, such as sharp or protruding items, can significantly reduce the risk of corneal ulcers.
- Feline herpesvirus (FHV): Cats infected with FHV are more prone to developing corneal ulcers. Vaccination against FHV can help prevent recurrent ulcers caused by the virus.
Preventive Measures
To minimize the risk of corneal ulcers in cats, it is important to take preventive measures and maintain a safe environment for your feline friend. Here are some steps you can take:
- Regular veterinary check-ups: Schedule regular visits to your veterinarian to ensure your cat’s eyes are examined for any signs of infection, injury, or underlying conditions that may increase the risk of corneal ulcers.
- Manage fighting and aggression: Cats engaged in aggressive behavior or fighting are more susceptible to eye injuries. Implement proper behavior management techniques and provide a safe and stress-free environment to reduce the risk of trauma to the eyes.
- Vaccination: Ensure your cat receives appropriate vaccinations, including the vaccine against feline herpesvirus (FHV), to prevent viral infections that can lead to corneal ulcers. Consult with your veterinarian to determine the appropriate vaccination schedule for your cat.
- Eye hygiene: Keep your cat’s eyes clean by gently wiping away any discharge or debris using a damp cloth or sterile saline solution. Regularly inspect the eyes for any signs of redness, swelling, or discomfort.
- Avoid irritants: Be cautious when using shampoos, liquids, chemicals, or dust around your cat, as exposure to such irritants can lead to corneal ulcers. Take care to prevent accidental contact with the eyes during grooming or cleaning processes.
By being proactive and implementing these preventive measures, you can significantly reduce the risk of corneal ulcers in your cat. However, if you notice any symptoms of corneal ulcers, such as squinting, rapid blinking, or discharge, seek veterinary attention promptly to prevent further complications.

Surgical Options for Severe Cases
When it comes to severe cases of corneal ulcers in cats, one surgical option that has shown promising results is the use of autologous buccal mucous membrane grafts. This procedure has been successfully used to manage deep or penetrating corneal lesions in both dogs and cats, providing a useful and economical alternative to other corneal grafts.
Autologous Buccal Mucous Membrane Grafts
Autologous buccal mucous membrane grafts involve harvesting grafts from the unpigmented superior labial mucosa, which is a tissue found in the inner lining of the cheek. This tissue is relatively abundant, easy to harvest, and can be used fresh, making it a suitable option for corneal repair surgeries.
The surgical procedure for corneal ulcers in cats with autologous buccal mucous membrane grafts typically involves the following steps:
-
Harvesting the graft: A biopsy punch is used to harvest grafts from the unpigmented superior labial mucosa. This tissue is carefully collected to ensure its integrity and viability for transplantation.
-
Securing the graft: The harvested graft is then secured to the healthy cornea using a combination of simple interrupted and continuous 9–0 polyglycolic acid sutures. This helps to ensure the graft’s proper placement and stability.
-
Additional conjunctival graft: In many cases, an overlying pedicle conjunctival graft is also performed to further support the healing process. This graft is placed on top of the buccal mucous membrane graft to provide additional protection and promote successful healing.
Surgical Procedure Details
A study reported that out of 27 eyes treated with autologous buccal mucous membrane grafts, 24 eyes showed healing of the ulcers and restoration of globe integrity. The follow-up period ranged from 14 to 2691 days, with a median of 549.2 days. Although the procedure had a high success rate, it’s essential to note that two cases required enucleation due to postoperative complications, and one case developed phthisis bulbi, a shrinking and degeneration of the eyeball (PubMed).
During the long-term follow-up, different grades of corneal fibrosis, vascularization, and pigmentation were observed in all cases. This indicates that while the ulcers healed and globe integrity was restored, there may be some residual changes in the cornea’s appearance (PubMed).
It’s important to consult with a veterinary ophthalmologist to determine if autologous buccal mucous membrane grafts are a suitable option for your cat’s specific case of corneal ulcers. The procedure’s success depends on various factors, including the severity of the ulcers and the overall health of the cat.
By exploring surgical options like autologous buccal mucous membrane grafts, veterinarians can provide effective treatment options for severe corneal ulcers in cats, helping to restore their feline patients’ vision and overall well-being.
