Red Eyes in Cats
Episcleritis in Cats
Episcleritis is a medical condition of the eye, where the episclera (white part of the eye) appears red, but does not have any related discharge or excess tearing. This condition is typically benign and easy to treat using topical ointments or eye drops. The inflammation may appear as either a nodule or a thickening of the sclera (white part of the eye). Although it is typically limited to the specific area, it is possible for the inflammation to spread to other areas of the eye. The outcome is generally positive with treatment, although there are possible complications to be aware of.
Symptoms and Types
Episcleritis may appear as a small growth or nodule in the eye. The nodule may be smooth, painless, pink, or tan in color, or it may look like a firm mass. In some cases, the inflammation may be more widespread, causing your cat's eye to become reddened and irritated. Your cat may also experience pain, show signs of discomfort, rub its eye frequently, have discharge, or even close the affected eye.
The development of this inflammation is thought to be related to the immune system. Also, bacterial infections or fungal infections, cancer (lymphoma), eye trauma, and glaucoma have been known to cause inflammation in the eye.
Your veterinarian will want to perform a full eye exam. Only then can your doctor begin to rule out possible causes for the inflammation. If there is a large mass located in the eye, a biopsy may be performed to rule out cancer. It is also possible that there is a foreign object lodged in the eye that is causing the inflammation or infection.
