Cicatricial entropion of upper eyelid (Q89626)

This is a condition in which the eyelid (usually the lower lid) folds inward, with areas of fibrous tissue (fibrosis) that replace normal skin after injury. 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). This diagnosis is of the upper eyelid.
