Understanding Corneal Ulcers in Cats
Corneal ulcers, also known as cat eye ulcers, are a common eye condition in cats that can lead to discomfort and potential vision problems. Understanding the causes and recognizing the symptoms of corneal ulcers is essential for prompt diagnosis and treatment.
Causes of Corneal Ulcers
Cat eye ulcers can have various causes, including trauma, infections, chemical burns, and foreign objects trapped under the eyelid. The most common cause of corneal ulcers in cats is trauma to the eye, which can be blunt or sharp, such as injuries from a thorn or claw. Other potential causes include scratches, ingrown eyelashes, trapped dirt, exposure to chemicals, and viral or bacterial infections. Recurrent infection with the feline herpesvirus (FHV) is a frequent cause of corneal ulcers in cats, leading to ulceration on the surface of the eye (Cornell Feline Health Center).
Symptoms of Corneal Ulcers
Recognizing the symptoms of corneal ulcers in cats is crucial for prompt veterinary intervention. Clinical signs of corneal ulceration include inflammation around the cornea, discharge from the eye, clouding of the cornea, and sensitivity to bright light. Cats may squint, rub their eyes, and show signs of vision problems when affected (Cornell Feline Health Center). If you suspect your cat may have a corneal ulcer, it’s important to seek veterinary care to ensure proper diagnosis and treatment.
Understanding the causes and symptoms of corneal ulcers in cats is the first step towards effective treatment. In the next section, we will explore the diagnosis and various treatment options available for cat eye ulcers.

Veterinary Examination
To diagnose corneal ulcers in cats, a comprehensive veterinary examination is crucial. The veterinarian will review your cat’s medical history and conduct a thorough eye examination. They may use eye drops containing fluorescein dye, which will highlight the ulcerated area with a greenish coloration. This diagnostic technique helps identify the presence and extent of corneal ulcers.
Treatment Approaches
The treatment of feline corneal ulcers focuses on controlling inflammation, reducing pain, and preventing the spread of bacterial or fungal infections. The specific treatment approach will depend on the severity and cause of the ulcer.
For superficial ulcers, antibiotic ointments are often prescribed to prevent secondary infections and support healing. In cases where the ulcer is caused by the herpesvirus, antiviral medications such as cidofovir or lysine may be prescribed to inhibit viral replication.
During the treatment process, it is important to closely follow the veterinarian’s instructions and administer medications as prescribed. Eye medications for corneal ulcers can sometimes have side effects. Cats may experience increased pain, sensitivity to light due to pupil dilation caused by atropine, or unpleasant taste if medication gets in their mouth (VCA Hospitals). If you have any concerns or notice adverse reactions, consult your veterinarian for guidance.
Regular re-examinations are crucial to monitor the healing progress of the corneal ulcer. The veterinarian may repeat the fluorescein stain test at intervals of one to seven days to determine if the cornea has healed. It is important not to discontinue treatment without veterinary guidance.
In cases where the corneal ulcer is severe or does not respond to medical treatment, advanced treatment options such as collagen contact lenses, third eyelid flaps, or surgical interventions may be considered. These interventions aim to promote healing and preserve the integrity of the cornea.
By seeking prompt veterinary care and following the recommended treatment plan, you can effectively address feline corneal ulcers and help prevent potential complications. Remember, the healing process may take time, and close monitoring is essential to ensure the best possible outcome for your cat’s eye health (cat corneal ulcer healing time).
Medical Treatments for Corneal Ulcers
When it comes to treating corneal ulcers in cats, various medical treatment options are available. These treatments aim to address the underlying causes, promote healing, and prevent potential complications. Two common approaches include the use of antibiotics and antivirals, as well as anti-inflammatory medications.
Antibiotics and Antivirals
Antibiotics are typically an essential component of the treatment plan for corneal ulcers in cats. This is because corneal ulcers pose a risk of serious complications associated with infection. Broad-spectrum antibiotics, such as Tricin eye ointment (Neomycin, Bacitracin, Polymyxin), are commonly prescribed for routine ulcers. In cases where signs of infection are present, such as ocular discharge or discoloration of the corneal stroma, more potent antibiotics like gentamicin may be recommended.
In addition to antibiotics, antiviral medications may be necessary for corneal ulcers caused by viral infections. These medications help combat the viral pathogens responsible for the ulceration. The specific antiviral prescribed will depend on the type of viral infection diagnosed by a veterinarian.
Anti-inflammatory Medications
Anti-inflammatory medications play a crucial role in the treatment of corneal ulcers in cats, particularly when uveitis (inflammation of the uvea) is associated with the ulceration. Uveitis can impede the healing process of the cornea, so systemic anti-inflammatory therapy is often recommended to reduce inflammation and promote healing. Nonsteroidal anti-inflammatory drugs (NSAIDs), such as carprofen, are commonly prescribed in these cases.
It’s worth noting that the use of medications like atropine may also be recommended for cats with corneal ulcers. Atropine is particularly useful when the pupil is small or if uveitis is present. This medication helps dilate the pupil and can aid in reducing intense miosis caused by superficial ulcers (VIN).
It is important to follow the veterinarian’s instructions regarding the dosage and administration of these medications to ensure the best possible outcome for your cat. Additionally, close monitoring of your cat’s progress during treatment is crucial to assess the effectiveness of the prescribed medications.
While medical treatments are often effective in managing corneal ulcers, more advanced treatment options like collagen contact lenses, third eyelid flaps, or surgical interventions may be necessary in certain cases. These options are typically reserved for more complex or severe ulcers. To learn more about these advanced treatment options, continue reading our article on advanced treatment options for corneal ulcers.
Remember, each cat’s case is unique, and treatment plans should be tailored to their specific needs. Regular veterinary examinations and diligent adherence to the prescribed treatment regimen are essential for successful management of corneal ulcers in cats. With proper care and treatment, most cats can experience a full recovery and regain their sight.
Advanced Treatment Options
When it comes to treating feline corneal ulcers, there are advanced treatment options available that may be necessary for more severe cases or ulcers that are not healing as expected. These treatment options include collagen contact lenses, third eyelid flaps, and surgical interventions.
Collagen Contact Lenses
Collagen contact lenses, such as traditional rigid contact lenses and collagen shields, can be beneficial for cats with corneal ulcers. These lenses are designed to protect the cornea from blepharospasm and other sources of ocular irritation. Collagen shields, in particular, are dehydrated purified collagen that is rehydrated with antibiotic or atropine eye drops and then placed onto the cornea. These contact lenses provide a barrier that promotes healing and helps alleviate discomfort.

Third Eyelid Flaps
In certain cases of deep corneal ulcers, dry eyes, or non-healing ulcers, third eyelid flaps (TEF) may be necessary. This procedure involves suturing the third eyelid over the ulcer to protect the cornea and facilitate healing. Third eyelid flaps can help improve the chances of successful healing, especially in more severe cases. For superficial ulcers, healing is generally expected to occur within three to five days without the need for third eyelid flaps (VIN). To explore options for medical treatment of corneal ulcers, refer to our article on cat corneal ulcer medication.
Surgical Interventions
For deeper feline corneal stromal ulcers, surgical interventions may be necessary to promote quick healing with minimal scarring. Some surgical options include conjunctival grafting, corneo-scleral transposition, and corneal transplantation. These procedures aim to facilitate rapid corneal healing and minimize the risk of scarring. Without surgical intervention, deeper ulcers may require corneal vascularization, which can lead to increased scarring (VIN).

It’s important to note that the choice of treatment will depend on the severity and specific characteristics of the corneal ulcer. Your veterinarian will thoroughly examine your cat and determine the most appropriate treatment approach. They will consider factors such as the depth of the ulcer, the presence of underlying conditions, and the overall health of your cat. Regular monitoring and follow-up visits are crucial to assess the progress of healing and make any necessary adjustments to the treatment plan.

Monitoring and Care
After initiating treatment for feline corneal ulcers, it is essential to closely monitor the healing process and take preventative measures to ensure the best possible outcome for your cat’s eye health.
Healing Process
In many cases, corneal ulcers in cats may heal naturally within a few days to a week without treatment. However, it is crucial to note that more severe cases may require medical intervention to prevent complications and promote healing. During the healing process, it is advised to avoid any interference that could worsen the condition. Self-trauma, such as scratching or rubbing the affected eye, can hinder the healing process and potentially lead to further complications. To prevent self-trauma, the use of an Elizabethan collar may be necessary.
To evaluate the progress of healing, your veterinarian may perform regular follow-up examinations. One common method for monitoring the healing of corneal ulcers is the fluorescein stain test. This test involves applying a special dye to the eye, which highlights any defects or abnormalities on the cornea. The stain test should be repeated at regular intervals, typically between one and seven days, depending on the severity of the condition and the progress of healing (VCA Hospitals). It is important not to discontinue treatment without veterinary guidance, even if the ulcers appear to be healing.
Preventative Measures
To prevent future corneal ulcers in cats, it is essential to take certain preventative measures. Avoiding potential sources of eye injury, such as sharp objects or exposure to chemicals, can help minimize the risk of corneal damage. Additionally, regular veterinary check-ups can aid in early detection of any underlying conditions that may contribute to the development of corneal ulcers.
Maintaining good overall eye hygiene is also crucial. This includes keeping your cat’s face clean and free from excessive discharge or debris. Be sure to follow your veterinarian’s recommendations for eye care, which may include specific cleaning solutions or tear-stimulating medications.
If your cat has a history of corneal ulcers or other eye issues, it is important to be vigilant and seek prompt veterinary care if any signs of discomfort or abnormalities arise.
By closely monitoring the healing process and taking preventative measures, you can help ensure the well-being of your cat’s eyes. Remember to consult with your veterinarian for personalized guidance and to address any specific concerns regarding your cat’s eye health.
Special Considerations and Success Rates
When it comes to treating feline corneal ulcers, there are certain special considerations to keep in mind. Additionally, understanding the success rates of different treatment options can help guide decision-making.
Side Effects of Treatment
While medications are commonly used to treat corneal ulcers in cats, it’s important to be aware of potential side effects. Cats may be sensitive to ophthalmic medication, which can result in increased pain after administration. For example, the use of atropine to relieve pain can cause the pupil to dilate widely, making the cat sensitive to light. Additionally, excessive drooling and pawing at the mouth may occur if the medication comes into contact with the cat’s mouth, as it may have an unpleasant taste (VCA Hospitals).
It’s crucial to closely monitor your cat during treatment and consult with your veterinarian if you notice any concerning side effects. They can provide guidance and make any necessary adjustments to the treatment plan.
Treatment Success Rates
Determining the success rates of various treatment options is essential in choosing the most effective course of action for your cat’s corneal ulcer. While success rates may vary depending on the specific case and treatment approach, it’s helpful to have an understanding of the potential outcomes.
A study conducted on the use of Clerapliq® for corneal ulcers in dogs reported a success rate of 86.6%, with a mean treatment time of 15.6 days. Out of the 15 eyes treated, 13 showed significant improvement in the dogs’ conditions (NCBI). Although this study focused on dogs, it provides valuable insights into the potential efficacy of treatment options for corneal ulcers.
It’s important to note that success rates can vary depending on individual factors, such as the severity of the ulcer and the overall health of the cat. Consulting with a veterinarian who has experience in treating corneal ulcers can provide valuable guidance and help determine the best treatment approach for your feline companion.
