Ectropion is an eversion of the eyelid away from the globe. Ectropion is classified by its anatomic features as involutional, cicatricial, tarsal, congenital, or paralytic. The out pouching of the eyelid is almost always that of the lower eyelid. The involutional form evolves slowly due to eyelid laxity. The cicatricial form can occur due to excessive sun exposure, burns, radiation, or surgical treatment to the lower eyelids. The tarsal form is uncommon and is due to the disinsertion of the lower lid retractor (capsulopalpebral fascia) from the interior tarsal border. Congenital ectropion is rare while paralytic ectropion are more recognizable for the associated facial muscles that are also paralyzed. Untreated, ectropion will lead to lagophthalmos and secondary exposure keratopathy. The patient with ectropion will complain not only of the abnormal appearance of the eyelid but also symptoms associated with exposure, such as tearing, sandiness, redness, and blurry vision.
