Dermatochalasis is a medical condition, defined as an excess of skin in the upper or lower eyelid, also known as "baggy eyes."〔 It may be either an acquired or a congenital condition. It is generally treated with blepharoplasty. ==Pathophysiology== Dermatochalasis is caused by a loss of elasticity in the connective tissue supporting the structure of the front portion of the eyelid. Normally, in Caucasians, the orbicularis muscle and overlying skin form a crease near the tarsal border.〔 In dermatochalasis, the excess tissues hangs down, over the front edge of the eyelid. The excess tissue can sometimes obstruct the visual field, especially the superior visual field. In severe cases, it may obstruct as much as 50 percent of the superior visual field.〔
