Involutional ptosis

Abstract

Aponeurotic ptosis, previously called senile or involutional ptosis, is the most common type of acquired ptosis. It is caused by a disinsertion or dehiscence of the levator aponeurosis from the tarsus. Clinical examination reveals a high lid crease, generally good levator function, and typically worsening of the ptosis on downgaze. These patients tend to do well with surgical correction, which involves advancement and reattachment of the levator aponeurosis to the anterior tarsal surface. © 2011 Springer Science+Business Media, LLC.
