Ptosis is the partial or complete drooping of the upper eyelid due to the incomplete or loss of function of the levator muscle (innervated by the motoneurotic nerve) and the Müller smooth muscle (innervated by the cervical sympathetic nerve), which can partially obscure the pupil in mild cases or completely obscure the pupil in severe cases. In order to overcome the visual impairment, patients often tighten their frontal muscles to raise the upper eyelid margin, resulting in horizontal wrinkling of the frontal skin, deepening of the frontal lines, and elevation of the eyebrows. In cases of bilateral ptosis, the head is often tilted up to see, resulting in a special posture. This is usually corrected by shortening of the levator muscle or by suspension of the frontalis muscle. This is an outpatient procedure that does not require hospitalization and requires only a few days of postoperative antibiotics.
