Ptosis – Introduction
Ptosis is a medical condition where drooping of the eyelid occurs due to the weak eyelid elevating muscle function. This disorder can affect one eye or both. Ideally, the lid position should allow 80 to 90% of the color aspect of the eye (iris) to be visible. In most cases, a patient showing anything less is considered to have ptosis. Some physical problems associated with this disorder are headaches due to eye and brow strain, inability to read for prolonged periods of time, as well as forehead wrinkles. These symptoms are related to patients with severe ptosis. However, patients with mild to moderate ptosis do not exhibit these symptoms apart from forehead wrinkles. Patients with mild ptosis may appear tired while those with moderate ptosis have a harsh appearance (see below images).
