What is Entropion?


Introduction 1

Entropion is an ophthalmological condition in which the eyelid margin attains an abnormal position by moving inward. Entropion causes irritation and damage to the eye surface. The inward turning lashes can rub against the cornea causing pain, blurred vision, and tearing. This condition is common in older individuals and can be treated with medical or surgical options. The lower lid is more commonly affected than the upper eyelid.

Some tests may rarely be done to rule out autoimmune conditions e.g anti basement membrane antibodies.
