Sally,
If it is actually uveitis, it needs a steroid administered to it. My
horse Pepsi had uveitis and went blind in the eye due to not doing this soon
enough, and my cat Buddy had it and responded well to the steroid. You just
don't
want to use a steroid if the eye is ulcerated. A special eye exam can tell
you that. There are prednisolone eye drops that they give to cats, and
potentially also atropine drops. Is your vet an internist or opthalmologist?
If
not, if you can afford it and there is someone nearby, I highly recommend
seeing
a specialist about this. An opthalmologist would be best.
