Description

Summary

This study intends to determine the number and percent of subjects initially diagnosed with divergence excess exotropia which would be reclassified as simulated divergence excess exotropia if tested after 24 hours of monocular occlusion (patching) or after prism adaptation for the distance angle.

Official Title

Divergence Excess/Simulated Divergence Excess Exotropia (DESDEE)

Keywords

Exotropia, Patching, Prism Adaptation
