Entropion occurs most commonly as a result of ageing. With age, the tendons and muscles that hold your eyelid taut against your eye stretches out and your eyelid starts to turn in. Occasionally, entropion is due to scarring of the inner surface of the eyelid, caused by inflammation, chronic infections or trauma.
Longstanding, uncorrected entropion can lead to gradual scarring of the cornea, as well as increase the risk of infection of the cornea. It is thus important to have this condition repaired before these complications permanently damage the eye.
If entropion is present in an eye requiring cataract removal, it is advisable to correct the lid abnormality first, before cataract surgery.
