Ectropion and Entropion
Ectropion is a medical condition in which the lower eyelid is turned outward so that the inner surface of the lid is exposed. The lower lid often has an inflamed and sagging appearance. Ectropion may result in dryness, irritation and tearing. The most common cause of ectropion is aging, which weakens the connective tissue of the eyelid and allows it to turn outwards. Lubricating drops may provide temporary relief of dry eye symptoms. Surgery is usually needed in order to tighten the eyelid muscles.
Entropion is a medical condition in which the eyelids are turned inward. It is extremely uncomfortable because the eyelashes constantly rub against the eye and cause redness, tearing, and a foreign body sensation. There are multiple causes of entropion, with the most common being age-related changes that result in an inversion of the lower lid. Medical treatments include ocular lubricants and drops, botulinum to relax the eyelid muscles, and the taping of the lower lid. Definitive treatment involves surgical correction.
