Introduction
Cats and dogs both have a third eyelid, also known as a nictitans gland, which is responsible for tear production. In some instances this gland falls out of place and it becomes visible in the corner of the eye. Cherry eye is rare in cats, and it has been diagnosed mainly in Burmese and Persian cat breeds. It is believed that this condition is genetically inherited, and it occurs as a result of weak connective tissue which holds the third eyelid in place. Treatment of cherry eye in cats can include repositioning the eyelid back into place or surgically tacking the eyelid to its proper position.
Treating Cherry Eye
Non-surgical options
While repositioning the third eyelid back into place is not a conventional treatment for cherry eye in cats, some veterinarians opt to try this procedure instead of turning straight to surgery. Repositioning the eye only takes a few minutes, and it is painless for the cat. This is not often a permanent solution, as the eye may continue to periodically slip back down, but in cases where the patient is not a good surgical candidate this procedure may be the best alternative.
Surgical options
In cases where the third eyelid will not stay at all after it is repositioned, surgery is the best treatment. During the surgery the veterinarian will reposition the third eyelid using permanent sutures which act as supportive connective tissue to hold the eyelid in place. Removal of the third eyelid is not recommended, especially in cats. It is believed that the third eyelid is responsible for the majority of tear production in cats. Removing the eyelid will result in a severe, painful, dry eye condition that requires lifelong medications.
If your cat has developed a cherry eye, try not to touch the eye. Do not try to reposition the eye back into place yourself as you may permanently cause harm to the third membrane or your cat’s eye. While cherry eye is not an emergency or life threatening situation, the cat’s eye should be examined by a veterinarian as soon as possible.
