Prolapsed Lacrimal

Prolapsed gland of the third eyelid (nictitans) is often referred to as “cherry eye.” The gland is actually one of two tear glands positioned around each eye in dogs and cats. The prolapse occurs due to a weakness of the connective tissues that hold the gland in place. The gland is normally attached out of sight to the base of the third eyelid, at the inside corner of the eye. When the tissue attachment releases, the gland rises up and becomes visible at the leading edge of the third eyelid. At that time, a smooth red mass will be seen.
