Entropion is an inward rolling of the eyelid. Although the exact genetic pattern is usually not known, the condition is considered to be breed-related in several breeds, including the Shar Pei, Chow Chow, Bulldog, Retrievers, and  Rottweiler.

 The treatment for entropion is surgery to remove some skin and muscle along the eyelid margin to obtain normal alignment of the eyelids.

The surgery can be performed after the age of 4-6 months depending on the patient's particular problems associated with the entropion, such as corneal ulceration caused by irritating lashes or hair.  Usually only one surgery is required but since the problem occurs in growing patients, additional correction is occasionally needed when the patient is an adult.
