Ectropion \Ec*tro"pi*on\, n. [NL., fr. Gr. ?, fr. ? a turning aside; ? from + ? to turn.] (Med.) An unnatural eversion of the eyelids. [1913 Webster] ||


n. a condition of loose eyelids, characterized by the turning outward of the lower eyelid.


Ectropion is a medical condition in which the lower eyelid turns outwards. It is one of the notable aspects of newborns exhibiting congenital Harlequin-type ichthyosis, but ectropion can occur due to any weakening of tissue of the lower eyelid. The condition can be repaired surgically. Ectropion is also found in dogs as a genetic disorder in certain breeds.
