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

Treatment and study plan

muscle transplantation

Procedure

transplanting a resected part of medial rectus to the already recessed lateral rectus muscle

Y splitting

Procedure

Y splitting of the recessed lateral rectus muscle

Primary outcomes

  1. Ocular alignment

    Time frame: from the operation till six months postoperatively

    To measure ocular alignment using prisms after lateral rectus recession with muscle transplantation versus lateral rectus recession with Y splitting

Secondary outcomes

  1. palpebral fissure height

    Time frame: from preoperative to 6 months postoperative

    Assess whether this is a change in palpebral fissure height pre- and postoperatively by measurement using a ruler

  2. ocular incomitance

    Time frame: from surgery till 6 months afterward

    The presence of ocular incomitance and gaze restriction using prisms and motility tests after surgery
