The eyelids are responsible for shielding the eyes from debris and bright light. Eyelids also help to keep the eyes moisturized as they spread tears over the surface of the eye while blinking. The eyelids are susceptible to certain conditions — some of which are merely cosmetic and others that affect the lids’ form and function.
ECTROPION AND ENTROPION
Ectropion and entropion are problems that affect the eyelid skin. Ectropion is a condition in which the eyelid turns outward, exposing the skin of the inner eyelid causing irritation. Entropion is a condition in which the eyelid turns inward, causing irritation. Lubricating eye drops can help to relieve some of the irritation of these conditions but surgical correction is usually necessary at some point.
The eyelids may droop for several reasons, including the age-related loosening of the eyelid skin, loosening of the tendon of the levator muscle that lifts the eyelid, a medical condition that paralyzes the nerve responsible for lifting the lid or as the result of an eye injury. Mild eyelid drooping can be fixed with Botox injections. In severe cases, the drooping upper eyelid skin sags into the line of sight and obstructs vision. The only way to correct significant eyelid droop is through eyelid surgery.
