Feline Herpes Ulcers Simplified

Feline Herpes Ulcers Simplified

From episode 172 on the Medicine feed, with Dr Izak Venter.

Some practical pearls from an ophthalmologist to simplify feline Herpes ulcers:

    • When you see eye ulcers in an adult cat, once you've ruled out dry eye, trauma etc, you can assume that the cat has herpes, especially if there is a history of a stressful event.

    • Classic Herpes ulcers will be unilateral, with superficial corneal erosion and a lip of unattached epithelial cells on the edge of the ulcer. (Geographic ulcer - like an indolent ulcer in a Boxer dog.) 

    • Trying to treat the ulcer without debriding those dead edges is pointless.  Put some local in, use a cotton swab, and debride aggressively, even if it means you’re peeling the cornea back across the entire eye.

    • DO NOT do a grid keratotomy. You’re likely to cause a corneal sequestrum. (Unlike in those Boxer ulcers, where you DO want to do it.) 

    • Dr Izak has some great tips on medical therapy in the full episode.
