Entropion is an inward turning of the lids

Explanation:
Entropion is the inward turning of the eyelid margin. When the lid turns toward the eye, the eyelashes and lid margin may rub against the cornea and conjunctiva, causing irritation, a gritty sensation, tearing, and a higher risk of corneal damage or ulcers if not addressed. It often involves the lower lid and can be congenital or occur with aging or scarring. In contrast, outward turning of the lids is ectropion, where the lid margin turns away from the eye and the inner surface is exposed. Drooping of the lid is ptosis, a sagging of the eyelid that can cover part of the pupil. Tear drainage relates to the lacrimal system and tearing (epiphora), not lid orientation.
