In brief

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.

You may qualify if…

• Diagnosed with divergence excess exotropia according to standard criteria (see Study Procedures for specifics)
• No prior strabismus surgery
• Able to cooperate with testing (by examiner determination)
