Entropion

Condition Overview

This condition, in which the eyelids roll inward, it the most common congenital defect of the eyelids. The breeds most commonly affected by entropion are the Chinese Shar-pei, Chow-Chow, Great Dane, Great pyrenees, St. Bernard, Bulldog, and the hunting breeds.

Symptoms

Corneal injuries are common from abrasion by the hairs. Most cases involve the lower eyelids. In dogs with large heads and loose facial skin (such as Chinese Shar-Pei, Bloodhounds, ans St Bernards), the upper eyelids may be involved.

Causes

It can also be caused by injury and long-standing eyelid infections that cause scarring.

Diagnosis

It may be difficult to distinguish entropion from blepharospasm. The best way to tell them apart is to administer a topical eye anesthetic. If the inverted eyelids are caused by blepharospasm, temporarily blocking the eye pain causes the inversion to disappear.

Treatment

Entropion requires surgical correction. Note that dogs who have had corrective surgery on their eyelids cannot be shown in conformation.

Many Shar-Pei puppies suffer from a condition called neonatal entropion. These puppies should have their eyelids everted (returned to a nartual position) with temporary sutures (stitches) at 3 - 5 weeks of age. If they do not outgrow the problem, plastic surgery on the eyelids can be performed at a later date.

Prevention

There is no known prevention for this condition.
