Plain-English summary
A young Great Dane was brought in with a rolled appearance of the third eyelid, known as the membrana nictitans. This condition, called eversion, is common in large dog breeds and usually happens without any prior health issues. While it mainly affects the dog's appearance, it can also lead to increased tearing and mucus discharge from the eye. Treatment options may include surgical correction to improve the look and comfort of the eye, which can help reduce any excessive tearing.

Abstract
Eversion of the membrana nictitans occurs in a number of large breeds of dogs including Great Danes, Weimaraners, German shepherds, akitas and springer spaniels. Inversion also occurs, but less frequently. These anomalies commonly appear early in the dog's life, usually without antecedant disease; thus suggesting a congenital predisposition. The central shaft of the T‐shaped cartilage of the nictitating membrane becomes curled, giving the membrana a rolled appearance. The effect is more damaging cosmetically than physically. However, an increase in tearing and mucus secretion may be noted.
