Spastic entropion of eyelid

Definition

This is a spastic condition in which the eyelid (usually the lower lid) folds inward. It is very uncomfortable, as the eyelashes constantly rub against the cornea and irritate it. Entropion is usually caused by genetic factors and very rarely it may be congenital when an extra fold of skin grows with the lower eyelid (epiblepharon). Entropion can also create secondary pain of the eye (leading to self trauma, scarring of the eyelid, or nerve damage).
