Which term describes inward turning of the eyelid?

Explanation:
Inward turning of the eyelid is described by the term entropion. This condition causes the eyelid margin to roll toward the eyeball, making the eyelashes rub against the cornea and conjunctiva. That rubbing can irritate the eye, cause tearing, and raise the risk of corneal damage if not addressed. Entropion is different from ectropion, which is the outward turning of the eyelid away from the eye, and from ptosis, which is the drooping of the eyelid, or blepharitis, which is inflammation of the eyelid margins without a turning motion. The word entropion specifically conveys the inward rotation, so it’s the correct term.
