A new method for eyelid elevation in glaucoma patients with ptosis during automated perimetry testing.

Abstract

Ptosis is a well-recognized confounding factor when interpreting superior visual field defects. As the current technique for eyelid elevation during automated perimetry is cumbersome and inconsistent, we developed a new technique. To evaluate its efficacy and feasibility, we studied a group of glaucoma patients with ptosis and superior visual field defects that had been attributed to nerve fiber layer defects.
