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 is the medical term for a drooping eyelid. It refers only to the upper eyelid; it does not refer to lower eyelid sagging. Upper eyelid drooping can sometimes affect your vision if the drooping is severe. Ptosis is not a disease, but a symptom of another condition that must be treated.
