ENTROPIAN AND ECTROPIAN

A healthy eye

_
Entropian, where the eyelid, along with the eyelashes, rolls into the eye, leading to possible ulcerations of the cornea.  Surgery is required to correct this condition.

Ectropian, where the eyelid rolls outward, and can also causes irritation to the cornea and conjunctiva.  This condition can sometimes just be cosmetic, with the eye looking red and droopy, however if there is irritation, corrective surgery may be required.
