My FIV+ cat has chorioretinitis. Is FIV the only cause, or are there others?
Updated On September 23rd, 2025
I read that FIV is one of the most common viral causes of chorioretinitis. If a cat is FIV positive and has chorioretinitis, is it automatically assumed that the chorioretinitis is caused by FIV? Or could there be other causes for it?

Hi and thanks for your request. There are many causes of chorioretinitis and even though FIV is quite common, generally speaking parasites, fungal infections, bacterial infection (e.g., Bartonella), other viral infections (e.g., feline leukemia, feline infectious peritonitis), autoimmune disease, cancer, toxicity (e.g., antifreeze poisoning, or adverse reaction to medications) are all possible. A clinical examination at your local veterinarian is essential to confirm these clinical suspicions and treat appropriately.

Thanks for using Petco Pet Education Center, formerly Petcoach! It does make infectious/inflammatory more likely though there is still a possibility that this is something else such as a tumor. I recommend following up with your veterinarian as they know the case better. Have a good day!
