What does eyelid ptosis describe?

Eyelid ptosis is a condition characterized by drooping of the upper eyelid, either partially or completely covering the pupil. It can affect one or both eyes and may be present from birth (congenital ptosis) or develop later in life (acquired ptosis). There are various underlying causes for eyelid ptosis, ranging from muscle weakness or nerve damage to aging-related changes in the eyelid muscles and structures. Ptosis can impact the individual's vision and may also have cosmetic implications. Treatment options for ptosis often include corrective surgeries to elevate the eyelid and improve visual function.
