Ectropion (ek-TROH-pee-on) is when your lower eyelid turns or sags outward, away from your eye, exposing the surface of your inner eyelid.
This condition can cause eye dryness, excessive tearing, and irritation. Ectropion may be due to several factors, including facial paralysis and injury. The most common cause is muscle relaxation due to aging.
If you have symptoms of ectropion, you should seek medical attention. Without treatment, ectropion can lead to serious problems with your cornea and even blindness. Eye lubricants can help ease symptoms, but surgery is usually necessary to achieve full correction. Most people who have the surgery experience a positive outcome.
