Ptosis can be caused by a number of factors that affect the muscles, nerves, or skin of the eyelids. The muscles that allow your eyelids to move up and downâcalled the levator musclesâcan become weakened from age or injury.
Ptosis can occur in one eye or both eyes at the same time. Ptosis may be caused by normal aging, injury to the eye or an eye disease. In most cases, it is caused by weakness of the eyelid muscle or eye nerve problems. Sometimes the condition is present at birth, referred to as congenital ptosis. If left untreated, congenital ptosis may prevent normal vision development, and may increase the risk of developing lazy eye.
