Comparative Study of Muscle Transplantation Versus Y Splitting Recession Technique in Treatment of Large Angle Exotropia

Comparative Study of Muscle Transplantation Versus Y Splitting Recession Technique in Treatment of Large Angle Exotropia

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.

Inclusion Criteria:

• Age should be of more than 6 years Exotropia of an angle ranging from 50 to 70 PD Myopic or hypermetropic refraction

Exclusion Criteria:

• history of previous squint surgery significant vertical deviation incomitant squint in the form of paralytic or restrictive disorder any neurological disease
