Orbital Septum Fibrosis in Congenital Ptosis Correlates With Eyelid Function: A Clinicopathologic Study

Abstract

Orbital septae in patients with congenital ptosis demonstrate histologic disorganization and fibrosis. When decreased levator function is observed clinically, septal fibrosis and/or disorganization is likely present. These observations suggest that debulking the fibrotic septum during congenital ptosis surgery may improve outcomes by releasing the eyelid from its congenitally tethered position, improving eyelid elasticity.
