Details and patient eligibility

About

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.

Enrollment

All

Ages

Under 17 years old

Volunteers

No Healthy Volunteers

Inclusion criteria

Diagnosed with divergence excess exotropia according to standard criteria (see Study Procedures for specifics)
No prior strabismus surgery
