entropion /entrō″pē·on/ [Gk, en + tropos, a turning] , turning inward or turning toward, usually a condition in which the eyelid turns inward toward the eye. In either the upper or lower eyelid, cicatricial entropion can result from scar tissue formation. Spastic entropion results from an inflammation or other factor that affects tissue tone. An inflammation of the eyelid may be the result of an infectious disease or irritation from an inverted eyelash. Compare ectropion. See also blepharitis.
