In general, if the ptosis is caused by a systemic muscle weakness, other muscles in the face, head, or body may be affected. A drooping eyelid can also be a symptom of a brain tumor or stroke, especially if it comes on within a few days or a few hours or if just one eye is involved.
Ptosis can have several causes. In patients with diabetes the droop may be caused by the paralysis of the nerve that supplies the muscles of the upper eyelid. Separation or stretching of the eyelid muscle where it connects to the eyelid, or an eye injury, can also result in eyelid droop.
