My cat is only 1 year old and just recently he developed some sort of white thing on his eye ball and his eye is very red and inflamed. I took him to the vet and they said it could be ulcerative keratosis but they didn't seem to be very familiar with it. They did a dye test and basically scraped the white stuff off the surface and gave me a topical anti biotic for his eye and told me to come back if it didn't go away. The white stuff has come back and the eye is still very inflamed. He doesn't seem to be in pain but he is definitely walking around with that eye closed or squinty. Anybody know anything about this or what I should do?? The picture is today, 9 days after vet visit.
