ptosis (blepharoptosis, droopy lid)
Ptosis is the relaxation of the upper lid and narrowing of the palpebral fissure (opening between eyelids). Senile ptosis is most frequently caused by a decreased muscle tone and relaxation of the skin. Symptoms of senile ptosis include a decrease in the visual field, a foreign body sensation if the lashes are pushed onto the cornea (trichiasis), and the cosmetic aspect of a droopy eyelid.
Treatment involves surgical shortening of the levator palpebrae muscle of the upper eyelid. If the pupils are not covered by the eyelids, surgery may be delayed for a period of time.
