My older cat's eye changed color and is red. Is she going blind now?

There are a couple of possibilities here for the changes to Creo's iris. One is iris atrophy, which is a normal aging change. This can often result in pigment change and a "moth-eaten" appearance to the iris or an irregular iris border. Another would be a uveal cyst, which is a darkly pigmented circular lesion that can be attached to the iris. Both of these are generally benign. If you notice any changes in Creo's vision, changes to the eye, or signs of pain (squinting, redness, swelling, etc.), have him re-evaluated by your vet just to be safe.

It is common for kittens to undergo an eye color change. If your cat is an older cat though, it may signify infection or more serious underlying disease. Any sudden change in eye color should be addressed by your vet or veterinary ophthalmologist.

It looks like Memo could have changes to the iris due to anterior uveitis or inflammation in the eye. This can cause the pupil to become smaller and the iris to change colors. It’s also possible that Memo has a growth on this eye. I would recommend seeing your veterinarian so they can examine Memo’s eye in person. They may want to check his eye pressure.

It could be iris melanoma but there is no way to know just by looking at a photo. You should have a veterinary ophthalmologist check the eye if you are really worried. At Cali's age I highly doubt it is melanoma but it is possible.

This can be a sign of a systemic disease. The inflammation in the eye can be a serious problem that needs treatment. I recommend a veterinary exam and lab testing to diagnose the problem and start him on the appropriate treatment.

I would be concerned that Ball might have inflammation in his eye that has caused the color change to his iris - this condition is known as anterior uveitis and can have many potential underlying causes. Growths on the iris might be another possibility. I'd recommend having his eyes examined by your vet. They may want to check the eye pressure.

Hello. I do not think putting the medication in the eye months ago is causing this situation with Lily now, but you definitely need to have this checked out by your veterinarian. A color change can indicate the presence of uveitis, a general term used to describe inflammation in certain parts of the eye. There are several possible causes or underlying diseases that can cause this, but only a thorough ophthalmologic exam will diagnose the problem. I hope you can have her seen soon.
