Ectropion - Overview

Definition of Ectropion:

Ectropion is the turning out of the eyelid (usually the lower eyelid) so that the inner surface is exposed.

Causes, incidence, and risk factors:

Ectropion is usually caused by the aging process and the weakening of the connective tissue of the eyelid, which causes the lid to turn out. It can also be caused by:

  • A defect that occurs before birth (for example, in children with Down syndrome)
  • Facial palsy
  • Scar tissue from burns
