Trichiasis
Introduction
Trichiasis is misalignment of eyelashes, which rub against the eyeball, in a person who does not have entropion. Trichiasis develops most commonly some time after Blepharitis (inflammation of the edges of the eyelids) or injury or damage to the eyelid or conjunctiva. Some people are born with an extra eyelid skinfold (epiblepharon) that causes the eyelashes to grow straight up into the eye or with an extra row of eyelashes (distichiasis). Trichiasis differs from Entropion and Ectropion (a condition in which the eyelid is turned inward) in that the eyelid position is normal.
