Why does my cat's one eye look lighter than the other in bright light?

It's a little difficult to tell in you picture but it looks like there is something in the anterior chamber of Lady's eye between the iris and the clear cornea - this might be inflammatory cells or the iris may be bowed forward. A cataract is an opacity on the lens behind the pupil. Lady's eye definitely looks abnormal and I would worry about her vision in that eye however - I would recommend having a vet examine the eye in person to determine what might need to happen next.

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.

Thank you for submitting your question regarding your cat. I recommend that he sees a veterinarian. He seems to have an opacity in his eye. This can be on the cornea (surface of his eye) or on the lens. He could have a scratch across his eye or even a scar. If the problem is on his lens, then a cataract is a possibility. His veterinarian will examine his eye with a special instrument called an ophthalmic scope. Some tests may be recommended as well. I hope this information helps!

Hello. It sounds like an inflammatory process in the eye called uveitis. You are doing the best thing for her by having this looked at quickly. Usually with proper treatment, these will clear up pretty quickly. Thanks for contacting Petco Pet Education Center, formerly Petcoach.

It looks like that left eye may have some ongoing damage ongoing problem with the cornea clear, (front part of the eye). Does she seem like she can see? Does she walk along walls (as though looking to be leaning in for a knowledge of where she is), does she bump into things? If she does not bump into things and DOES seem to be able to see, then her pupils are probably functioning appropriately even if you can't see it. However it is possible too that she has some lens changes... the lens in the left eye looks a bit cloudy in the picture. As long as she's an indoor cat, it shouldn't matter too much whether or not she can see. Most blind animals do quite well and function great as pets. However, if she seems uncomfortable or painful, I would encourage you to take her to your vet to have the eyes re-evaluated. Thanks for asking Petco Pet Education Center, formerly Petcoach!

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! I can think of 2 things: 1) uveitis which is inflammation of the uveal structures in the eye. It can cause light sensitivity. It is diagnosed by measure the intra-ocular pressure. It would come back low. Causes of uveitis in cats is trauma to the eye, feline leukemia, infection, metabolic disease, etc. 2) Haws syndrome. Which is GI disease. In a young cat I would be sure he gets dewormed regardless of a normal stool sample. Consider a dietary change if deworming doesn't resolve the issue. I hope Sofia does well!

Thank you for visiting Petco Pet Education Center, formerly Petcoach. A blurry spot can mean that you pet either has a scar on the cornea or it could indicate a corneal ulcer, depending on how this looks. There is also the potential it could be nuclear sclerosis, if it is a deeper opacity that you are seeing. Please submit a photo of the eye in question for clarification on what this likely is, or have your vet do a physical exam to confirm. If it is a corneal ulcer, it needs to be confirmed with an eye test through your veterinarian and then treated with medication. Corneal ulcers however cause excessive blinking and eye discharge. Nuclear sclerosis is common in older cats, and I'm not sure how old your cat is, but they don't require any treatment.. And corneal scars are basically scarring from a previous corneal injury, which typically are permanent and don't require treatment. I wish you the best moving forward with your fur baby. Take care.
