Ectropion of the lower eyelid usually occurs when the lid margin flips outward, thus leaving the eye and causing exposure of the conjunctiva. There are three causes of this condition: 1) scarring, such as surgery, trauma, burns, or ulcers of the eyelid, which cause local scarring that leads to ectropion; 2) age-related ectropion, which is caused by the weakening of the orbicularis oculi muscle in the elderly, leading to laxity of the skin or ligaments of the eyelid, which causes ectropion; and 3) paralytic ectropion, which is caused by the loss of contraction of the orbicularis oculi muscle due to facial nerve paralysis. Ectropion is a condition that occurs when the facial nerve is paralyzed, resulting in the loss of contraction of the orbicularis oculi muscle. For this disorder, surgical correction is recommended primarily.
