Overview
This study is designed to correct large-angle exotropia by monocular surgery. It compares two augmented recession techniques, which are recession with muscle transplantation and recession with Y splitting.

Exclusion Criteria:
- history of previous squint surgery significant vertical deviation incomitant squint in the form of paralytic or restrictive disorder any neurological disease
