Corneal Ulcers in Cats: Advanced Welfare Management

An in-depth guide to feline corneal ulcers, from superficial abrasions to deep stromal ulcers, with welfare-centred management.

Key Facts

Corneal ulcers range from superficial epithelial erosions to deep stromal ulcers
Feline herpesvirus is a major cause of corneal ulceration in cats
Deep ulcers risk corneal perforation causing vision loss and extreme pain
Indolent (boxer) ulcers in cats are less common than in dogs but do occur
Treatment varies by depth: from topical antibiotics for superficial ulcers to surgery for deep lesions
Pain management is essential as corneal ulcers are intensely painful

Welfare Considerations and Management

Welfare-centred corneal ulcer management requires accurate assessment of ulcer depth to guide treatment. Superficial ulcers are managed with topical antibiotics and pain management. Herpesvirus ulcers require antiviral treatment (famciclovir, cidofovir drops). Deep stromal ulcers approaching Descemet's membrane require urgent specialist referral — conjunctival grafts or corneal transplants may save the eye. Descemetoceles (perforation-threatening ulcers) are surgical emergencies. Elizabethan collars prevent self-trauma during healing.

What You Can Do

Seek prompt veterinary assessment for any eye showing pain, cloudiness, or discharge
Ensure appropriate pain management — corneal ulcers are extremely painful
Apply all prescribed eye medications precisely at the instructed frequency
Use an Elizabethan collar consistently to prevent self-trauma during healing
