Ectropion is the hanging out of the free edge of the lower eyelid. The most common causes are scarring (due to burns or trauma), the senile (the most common: due to the aging of the tissues of the eyelid, which become saggy and unstructured), and the paralytic (after facial paralysis like Bell’s).

Symptoms begin with the dryness of the zone, causing discomfort and redness. Treatment begins with artificial tears hydration and eyelid reconstructive surgery as the final treatment.
