Upper Eyelid Ptosis Revisited


Blepharoptosis, commonly referred to as ptosis is an abnormal drooping of the upper eyelid. This condition has multiple etiologies and is seen in all age groups. Ptosis results from a congenital or acquired weakness of the levator palpebrae superioris and the Muller’s muscle responsible for raising the eyelid, damage to the nerves which control those muscles, or laxity of the skin of the upper eyelids. Ptosis may be found isolated, or may signal the presence of a more serious underlying neurological disorder. Treatment depends on the underlying etiology. This review attempts to give an overview of ptosis for the primary healthcare provider with particular emphasis on the classification, salient features of each of the subtypes, clinical evaluation, and treatment.
