Anisocoria In Cats – In cats, the student is an elliptically-shaped opening at the center of the iris that allows light to pass through the eye to the retina. The pupil constricts or dilates (expands) according to the quantity of light which enters the eyes, with both students normally dilating in dim light and constricting in bright light. Anisocoria is a condition where the two students of their cat’s eye are different sizes; in other words, one student is bigger than the other. Sometimes, the abnormal pupil might be the one which is smaller and in other cases, the abnormal student might be the one which is larger.
“Anisocoria occurs unexpectedly, you should seek veterinary attention immediately”
If anisocoria occurs unexpectedly, you should consider this an emergency situation and seek veterinary attention immediately to lower the possibility that your cat’s vision will be permanently affected.
In all instances of anisocoria, the pupil in one eye will probably be larger or smaller than the one in the other eye. Sometimes, that may be all that you notice. In other instances, depending on the underlying cause, the white portion of the affected eye may be red, the cornea may be cloudy or bluish in colour, there could be a discharge from the eye, the eyelid on the affected eye may be droopy, the cat may be squinting or rubbing in its eye, or the cat may be less active than normal.
What’s the reason behind anisocoria diagnosed?
Based on these preliminary findings, your vet may do some additional, more specific testing. Your vet may quantify the tear production and intraocular pressure (pressure inside the eyes) for each eye. The cornea may be stained with fluorescein dye to search for underlying corneal accidents or accidents, and conjunctival scrapings or biopsies may be obtained and sent to a diagnostic lab for technical testing. Blood tests may be conducted to determine whether the problem is related to a systemic illness such as feline leukemia.
In some instances, your veterinarian may suggest a referral to a veterinary ophthalmologist for further diagnostic testing.
How is anisocoria handled?
The treatment of anisocoria is dependent entirely on the root cause of the problem, and specific treatment will be tailored specifically to the identification. Your veterinarian will discuss the treatment options which are acceptable for your cat’s individual conditions.
Can my cat recuperate?
“Prognosis for complete recovery is dependent upon the origin of the anisocoria.”
The prognosis for complete recovery is dependent upon the origin of the anisocoria. Sometimes, your cat may need long-term medication to control the underlying cause. If your cat became blind because of the underlying disease, it’s very improbable that the blindness will be reversible.
