The turning outward of the eyelashes and eyelid. Ectropion (of the upper eyelid) is accompanied with retrotarsal atrophy. Ectropion (of the lower eyelid) is caused by orbicularis muscle weakness, and/or prolapse of adipose tissue.
(ek-TROH-pee-un). Outward turning of the upper or lower eyelid so that the lid margin does not rest against the eyeball, but falls or is pulled away. Can create corneal exposure with excessive drying, tearing, and irritation. Usually from aging.
the eyelid is turned outwards away from the eyeball, often accompanied by a disturbed lacrimation (secretion of tears), mostly caused by age-related tissue laxity, more rarely by an inflammation or cicatrization (scarring) of the eyelid.
