The most distinct sign of cherry eye in cats is red mass that seems to pop out of the eye. The mass is actually the gland of the third eyelid that is protruding from the inner corner or one or both of the cat’s eyes. Unlike humans who have two eyelids, cats possess there. The third eyelid is called the nictitating membrane. Normally, the membrane is not visible because it is well-anchored to the surrounding tissue. Its main functions involve protecting and moisturizing of the eyeball by contributing to tear production. Cherry eye occurs when the gland of the third eyelid turns inside out, making the gland more prominent, making it appear as a bright red mass bulging right inside the corner of the cat’s eye(s).

There are no medical or surgical procedures that can prevent the problem in cats without risking serious side effects. While it is possible to have the third eyelid surgically removed, the cat will require life-long treatment with topical eye drops to keep the eye moisturized, as well as anti-inflammatory medication so the cat won’t suffer from pain and discomfort associated with dry eyes. If your cat has developed cherry eye in one or both eyes, make sure to take him to your Isle of Palms, SC vet for proper attention and treatment.
