Idiopathic aponeurotic ptosis in young adults

Abstract

The author reports two cases of progressive, bilateral, aponeurotic ptosis of the upper lid in young adults with no history of trauma or lid edema, and no sign of neuro-muscular disorder. He hypothesises that the ptosis could be a late manifestation of a congenital weakness of the levator-muscle attachment to the tarsus and may result from a developmental anomaly of the anterior portion of the superior orbital mesodermic complex.
