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.
What is a droopy eyelid or ptosis? A drooping eyelid or ptosis can be present at birth (congenital) or can occur later in life (acquired). Poor development of the levator palpebrae superioris muscle in the upper eyelid can lead to an inability to properly open the eye. It is the most common cause of congenital ptosis.
