Ectropion is the outward turning or eversion of the lower lid margin where the mucosal surface of the lid is no longer in apposition to the globe. Untreated, this condition may result in conjunctivitis or exposure keratophy. There are several types of ectropion including involutional (age-related laxity), cicatricial (scar), paralytic, and congenital. The appropriate medical or surgical treatment for this condition is largely determined by the etiology of the disease.

Patient Presentation and Evaluation

Patients with ectropion may present with complaints related to conjunctival and corneal exposure such as epiphora (tearing), irritation, mattering, and edema (Frueh and Schengarth 1982). The practitioner should note the position of the lid margin and the position of the puncta compared to normal anatomy. In the normal lower eyelid, the lower lid rests at the limbus in apposition to the globe with no sclera visible between the lower lid margin and the limbus.
