Entropion & Ectropion
As you age, the major tissues and elasticity that support the eyelid can loosen, causing the eyelids to droop, turn outward, or turn inward. An eyelid that does not function properly can lead to ocular issues and damage. When an eyelid is turned outward, it can lead to chronic tearing because the tear duct cannot properly drain the tears and fluid in the ocular space. When an eyelid is turned inward, it can irritate the eye due to the eyelashes rubbing against the surface of the eye.
Entropion is an eyelid dysfunction that occurs when the upper or lower eyelid and eyelashes turn inward towards the eye, causing the lid and lashes to rub against the cornea and conjunctiva.
Ectropion is an eyelid dysfunction that occurs when the lower eyelid turns outward and does not protect the eye. Consequently, the cornea and conjunctiva may become exposed and irritated. Often the edge (margin) of the lower lid is red. Ectropion can affect one or both lower eyelids.
