Eyelid malposition includes a variety of conditions such as in turning (entropion) or outward turning (ectropion) of eyelids, inward-turning eyelids (entropion) misdirected eyelashes irritating the eye (trichiasis), and eyelid laxity or inability to close the eyelids (lagophthalmos). These conditions can result from age, inflammation, scarring, facial paralysis, trauma, congenital malformation, or disease. Eyelid malposition can cause chronic eye irritation, poor eyelid closure and dry out of the eye, mucous discharge, blurred vision, excessive tearing, infection, corneal damage, and impaired vision.
