causes of ptosis of eyelid
Sometimes, a head injury, eye trauma or another condition or disease can cause ptosis. Generally, this occurs when there is either damage to the âlevatorâ muscles that hold the eyelids up, or damage to the nerves which control these muscles.
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 downâcalled the levator musclesâcan become weakened from age or injury.
