Bilateral palpebral ptosis . cause may be aging ,myasthenia gravis , hypothyroidism and others
This condition is related to old age, but is technically not called ptosis...which has to do with weakness in levator palpebrae superious.
Answer : Dermatochalasis
Discussion - defined as an excess of skin in the upper or lower eyelid, also known as "baggy eyes"[SUP] [/SUP]. It may be either an acquired or a congenital condition. It is generally treated with blepharoplasty.
Dermatochalasis is caused by a loss of elasticity in the connective tissue supporting the structure of the front portion of the eyelid.[SUP][/SUP] Normally, in Caucasians, the orbicularis muscle and overlying skin form a crease near the tarsal border.[SUP][/SUP]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.[SUP][/SUP] In severe cases, it may obstruct as much as 50 percent of the superior visual field.
So we can call this as mechanical ptosis.
