Ptosis is a drooping or sagging of the upper eyelid, which may affect one eye or both. Ptosis is the medical name given to the condition of droopy eyelids. It is most common in older people, although it can occur as a congenital or birth defect, or as a result of an eye injury or disease.
There are two types of ptosis: acquired and congenital. Congenital ptosis is present at birth and is usually due to the lack of development of eyelid muscles called levators. Acquired ptosis is the most common type, and is usually due to the muscles that elevate the eyelid becoming weak, thin, or stretched with age.
