"Glossary Term: Cherry Eye"

Definition: Cherry eye is a common term for a prolapse of the third eyelid (nictitating membrane) of dogs. This produces a very red lump in the inside corner of the eye (or eyes, if both are affected).

The cause of cherry eye is not fully known, but thought to be a weakness in the tissue that normally holds the gland in place.

This condition is not usually painful to the dog, but unsightly and will interfere with the normal tear production for that eye, as it contains a tear gland that is responsible for a portion of the tear production of the eye.

Treatment can be one of two options: replace the eyelid and try to save the gland, or remove the eyelid and the gland. A possible risk of removal is the development of dry eye or keratoconjunctivitis sicca (KCS) later in life.
