My cat is blind. Can he regain vision if his pupils react to light?

There is anisocoria (the two pupils are unequal in size) and possibly ptosis of the upper eyelid (the eyelid cannot open normally) on the left side (where the pupil is bigger). There are many causes that can provoke this presentation: -Corneal injury such as an ulcer. -Disease or injury to the brain or to the nerves running to the affected eye, such as Horner’s syndrome. -Glaucoma, a disease in which there is increased pressure within the eye (the pupil in the affected eye will be dilated). -Uveitis, or inflammation of the interior of the eye (the pupil in the affected eye will usually be constricted). -Retinal disease. -Scar tissue formation between the iris and the lens (called posterior synechia), a condition that may develop following uveitis. -Iris atrophy (a decrease in the amount of tissue within the iris) usually a degenerative change associated with aging. -Congenital defect of the iris, in which the iris tissue does not develop properly. -Cancer within the affected eye. -Spastic pupil syndrome - a syndrome that may be associated with feline leukemia virus infection. -Other infectious diseases such as feline immunodeficiency virus or toxoplasmosis. Unfortunately is difficult to be more specific than that and a clinical examination at your local veterinarian is essential to confirm these clinical suspicions and treat appropriately. Antibiotics may be needed.

I would guess that Ebony may have had retinal detachment secondary to high blood pressure. Kidney disease can cause increased blood pressure. If her retinas partially reattached she may have regained some vision.

It is not normal at all that Leo's pupils stay wide when he has a light shined near them. They should constrict in the presence of light. This can be a sign that Leo is blind, and I would have him seen by a vet today. The vet can confirm he is blind. If Leo is blind, it is recommend to making him an indoor only cat if he isn't already one.

Hello and thank you for reaching out to Petco Pet Education Center, formerly Petcoach. Small or constricted pupils may be a sign of uveitis, which means inflammation in the front chamber of the eye. This can be due to infectious causes (bacterial/viral/fungal), high blood pressure, immune-mediated diseases or trauma, among other things. Cats with uveitis are often painful, however, and will show squinting of the eyes, will be sensitive to light, are often hiding, etc. It is possible that he has no ocular issues, and that you have just never observed his pupils in a dark room (this is very hard to do!). You can test if he can see by gently motioning toward his eyes with your hand (called a menace response) to see if he blinks. If he is squinting his eyes, has abnormal discharge (yellow/green, thick/mucoid), or very red conjunctiva, I recommend bringing him to your veterinarian to be evaluated. I hope this is helpful!

This sounds like he may have hurt himself, when he banged his face. It could also be that he has high blood pressure and that often makes cats temporarily blind. The faster the blood pressure is treated the more likely your kitty will regain his eyesight. Please take him to a veterinarian preferably right away, as either of these conditions (injury or high blood pressure) are signs of a serious health problem. He is purring because he is worried and afraid, and cats not only purr when they are happy, but also to appease other cats and people ("Please don;t hurt me, I am not going to hurt you).

Hi and thanks for posting on Petco Pet Education Center, formerly Petcoach! This doesn't sound normal to me and good thinking with the at home vision tests. There may be something abnormal going on with his vision that should be checked out with an eye exam at your veterinarian's office. There, your vet should be able to tell you what the issues with his eyesight may be. I hope this helps!

Retinal degeneration can result in blindness and therefore a lack or reduced response to all of the visual reflexes. By its nature - the degenerated retina is abnormal and would appear abnormal on a specialist eye exam by the time the patient had become blind
