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.
In addition, some people may be born with eye muscles that are weaker than normal, causing them to develop ptosis at a young age. Nerve damage can contribute to ptosis as well. A common cause of ptosis is Hornerâs syndrome. Hornerâs syndrome is a form of nerve damage that occurs in the face and eyes. Itâs usually the result of an underlying condition.
