Blepharochalasis is the technical term for an excess of skin on the eyelid. Eyelid skin sags with age and may run in families.
If there is a lot of excess skin, the field of vision may be limited. A resulting increased tension of the eyelid elevators can lead to increased headaches. The headache is often caused by compensatory over-tensioning of the muscles of the forehead.
The over-tension of the forehead muscles favors the formation of deep wrinkles on the forehead. Blepharochalasis can be treated by blepharoplasty.
