Ectropion is an abnormal eversion (outward turning) of the lid margin away from the globe. This is a condition in which your eyelid — typically the lower lid — turns out. This leaves the inner eyelid surface exposed and prone to irritation. Ectropion is more common in older adults. In severe ectropion, the entire length of the eyelid is turned out. When ectropion is less severe, only one segment of the eyelid sags away from the eye.
The prevalence of involutional lower lid ectropion in elderly patients in Brazil has been estimated at 2.9%. The primary morbidity is associated with corneal/conjunctival exposure. Tearing may also cause significant patient complaints. Ectropion can affect patients of any age but is most commonly seen in older adults.
