​Entropion

Entropion is a disorder of the eye lids in which the eye lids turn inwards. As a result, the eye lashes rub against the eyes, causing irritation, redness and corneal abrasions. Entropion is a more common disorder amongst the elderly and usually affects the lower eye lid. It may occur in one or both eyes.

Entropion progresses slowly, with symptoms barely noticeable at first. However, as it advances, eye lid movement may become difficult, and may lead to scarring of the eye ball, eye infections, and damage to the cornea, such as corneal breakdown and ulcers. 

Causes of entropion include age-related weakening of the muscles, scars or previous surgeries or recurrent eye infections. In rare cases, a child may be born with this disorder (congenital entropion).
