ectropion
Pronunciation: ek-TROH-pee-on
Outward turning of the eyelid margin away from the globe, often requiring surgical correction to restore proper eyelid position and function.
Full Definition
Ectropion is a condition where the lower eyelid margin turns outward, exposing the tarsal conjunctiva and creating functional and aesthetic problems. This malposition can result from aging with loss of tissue elasticity, facial nerve paralysis, cicatricial changes from trauma or previous surgery, or congenital abnormalities. Patients typically experience tearing, irritation, and potential corneal exposure problems due to inadequate eyelid contact with the globe. Surgical correction depends on the underlying etiology and may involve horizontal tightening procedures, full-thickness skin grafts for cicatricial cases, or muscle reinnervation for paralytic ectropion. The goal of treatment is to restore proper eyelid-globe apposition while maintaining natural eyelid contour and function. Careful preoperative assessment is essential to determine the appropriate surgical approach.
Usage
Usage note: Specify etiology (senile, cicatricial, paralytic, congenital) when documenting ectropion cases.
