Will a cats pupils react to light if they have retinal degeneration?

Will a cats pupils react to light if they have retinal degeneration?
My cat was recently diagnosed with retinal degeneration. It was brought on by an excessive dosage of Baytril. (prescribed by an ER vet) He seems to have some vision left. He almost seems to have tunnel vision or to be far sighted. His pupils are very large at night and will stay that way, but when he is in natural light they retract back down to normal. Is this a sign that he does still have some vision?

Dilation is handled by the iris, and may very well be independent of the retinal problem.

You should check with your vet – or an ophthalmologist.

My cat had detached retina and was blind for a few days. During that time his pupils stayed the same size. The Vet was able to prescribe something that restored his sight. We must give it to him every day but we don’t mind. You might ask your Vet about that.
