Hi XXXXXXXX,
I am not sure what you are trying to describe...because the cornea does not contract. The cornea is the front part of the eye and it is clear...it does not move.
Are you talking about that she cannot close her eyelids on one side?
Or perhaps that her third eyelid will not go back down on one side?

sorry, about my description.
I meant to say the iris.
One eye (the right one) as the light shines it
stays at the same aperture, while the other iris
goes small when there is plenty of light and
open wide when is not.
Please help on this.

Hi XXXXXXXX,
How long has your cat's eye been this way?
Does your kitty scratch at her right ear at all?
Is the pupil (the black part inside of her iris) of her right eye staying very large or very small?
If you shine the light into it (like with a flashlight), does it try to get smaller even slightly, or not move at all?
When looking at her right eye, are the eyelids held closed more than the left eye? Is her third eyelid (the pink fleshy inner eyelid) visible?
Is she pawing at her eye at all?
Is she able to walk normally?

1.- i happend around 10-7hrs ago. for sure.
2.- she is not scraching any ear and is pretty normal.
3.- the pupil on the right side is staying large.
4.- I tried the flashlight, and she tries to close her eye (the bad one) when I do this. I dont see a noticeable contraction. hard to say.
if it moves is impossible to see.
however, i see a contraction on the good eye when i shine the light there. ( flash the light independently to each eye by the way)
5.- Her eyelid are open the same, no visible or abnormal 'winking'
6.- no pawning and she is walking normal, even playing at times.
7.- I can see some fleshy stuff in both eyes except that the bad eye is a little more back that the other.
I am so worry about this. She is an indoor cat,
really good food all the time and well taken care of, never goes out.
any ideas.

Answer
Hi jelopez,
What you are describing is a condition called anisocoria (where the pupils are not the same size at the same time). There are amny different things that can cause this, but based on what you are describing, it sounds like your cat may have damage to her ophthalmic nerve behind her eyeball or she may have some brain disease.
I recommend that you take her in to see the veterinarian as soon as possible. The vet will be able to do a full neurological examination on her to determine if this nerve is the only one affected, or if she does have signs of other neurological problems. Then, a proper list of differentials can be generated and a course of tests outlined to determine what the problem is.
I hope that this information is of help to you, and I wish you the best of luck with your kitty. Please let me know if I can be of further assistance.

Accepted Answer
Brain tumors or generalized brain inflammation will often cause signs like seizures, difficulty walking, changes in attitude or behavior, constant walking in circles, head tremors, etc... It is really very different in each case. In some cases, the first signs are very subtle, like the anisocoria.
I am sorry ot be the bearer of some not so great news. You should seek out the help of a specialist in neurology, as some brain tumors in cats are resectable. This may be a possibility for your cat because she is so young.
I wish you the best of luck with your kitty.
