Ptosis is the medical term for a droopy eyelid. The upper eyelid edge falls from his normal position. This can occur at birth or slowly develop with age. Ptosis can therefore block the upper part of one’s vision. Some patients compensate by raising their eyebrows or tilting their head back to see better. This, many times, is accompanied by excessive skin of the upper eyelids. This is corrected surgically by removing the excess skin and tightening the tendon of the muscle that is responsible for raising the eyelid. If the ptosis is interfering with vision, it is usually covered by medical insurance.
