What is ectropion? Ectropion is an abnormality of the eyelids in which the lower eyelid rolls outward or is everted. This causes the lower eyelids to appear droopy. Ectropion exposes the delicate conjunctival tissues that line the inner surface of the eyelids and cover the eyeball, causing drying of the tissues, resulting in conjunctivitis.
Lower lid ectropion is a very common condition in older persons. Frequency increases steadily with age. Defined as an eversion of the eyelid away from the globe, the condition is classified according to its anatomic features as involutional, cicatricial, tarsal, congenital, or neurogenic/paralytic.
