Eye Ulcer, then brown spot , sphynx

Hi vets please help me … First my sphynx had an ulcer which he was given treatment terramycin which he still uses it. After 10 days of the ulcer I took him for a follow up and the vet says that the brown spot is a scar something like that, which we will need to treat with steroids but after his ulcer is completely healed. He said to go back in two weeks. He uses the E-collar. Is this correct or he has something else? Im going crazy and i know he is tired of the collar.  Please help me understand whats happening to his eye.

Hello - I wonder whether your cat might have keratitis, an inflammatory change to the cornea, which can present secondarily to an ulcer, to dry-eye (a reduction in tear quality which can, in itself, cause ulcers), or to various other problems such as viral infections.  Steroids can indeed worsen ulcers and prevent them from healing, so I agree with your vets' decision to withold them.  I haven't actually heard of them helping the scar to heal at a later date, but I am no opthalmologist and your vet may well have good evidence for this.  Testing the quality of the tear-film could monitor for dry-eye if it were thought to be a factor.  From this 2D picture, I cannot diagnose keratitis;  the colour in your cats' eye could obviously go deeper than the cornea, but your vet will have viewed the eye properly in 3-D and I would expect them to have checked if that were the case.  Wishing you the best of luck with this interesting case and please let us know whether or not the condition resolves.

I have re-read your question and see that you ask 'is this correct' - I just want to may it clear that I have no offered an alternative diagnosis here;  that the word 'keratitis' simply means 'inflammation on the surface of the eye,' which is a blanket term, not a diagnosis, and could colloquially be described as 'a scar on the eye.'  In every case, your vet is in a much better position to say what is going on thay we are; ours are suggestions only because eyes ought to be diagnosed in three dimensions, not from photographs.  For example, another eye looking just like this on a photograph, might have the scar at the back of the eye - a melanoma or uveal cancer  - and in just two dimensions, I would not be able to rule it out.  Fortunately, your vet would; for this reason, we are a support site only and no replacement for your vets.
