What is an ectropion?
Ectropion is the outward turning of the eyelid margin. Usually the lower lid is affected. Several types of ectropion have been recognised:
- congenital,
- involutional,
- spastic,
- cicatricial,
- mechanical.
Involutional ectropion is the most common type of ectropion caused by a flaccid eyelid. When the eyelid is turned outward and its edge does not touch the eyeball, the conjunctiva becomes dry and prone to infection. Chronic ectropion is manifested by a pronounced reddening and swelling of the eyelid. Ectropion patients report feeling a foreign body in the eye, tearing (lacrimation) and accumulation of cloudy fluid in the conjunctival sac.
