Ectropion is a turning outward of the lower eyelid. The eyelid’s exposed inner surface becomes dry and sore, and the eye may water continuously. Because the eyelids cannot close fully, the cornea is exposed and vulnerable to damage or infection.
Ectropion is usually due to aging, but may also be caused by damage to a facial nerve.
Treatment is with surgery to tighten the eyelid. Entropion is a turning inward of the upper or lower eyelid, or both. As a result, the eyelashes rub against the cornea, causing pain, irritation, and eye watering.
Constant rubbing may scar the cornea, leading to loss of vision. Entropion is commonly due to aging, but may also be due to the eye infection trachoma. It can usually be corrected with surgery.
