Official title
A Comparative Study Between Three Surgical Techniques in Large Angle Exotropia: Bilateral Lateral Rectus Recession With Medial Rectus Resection, Bilateral Medial Rectus Resection and Resection-Transplantation
Overview
This is a randomized comparative interventional study that aims to compare the surgical outcomes of correcting large angle exotropia (≥50 prism diopter) by three different surgical techniques including: 1/ bilateral lateral rectus muscle recession with unilateral medial rectus muscle resection 2/bilateral medial rectus muscle resection, 3/unilateral medial rectus muscle resection with lateral rectus muscle transplantation,
Detailed description
This is a randomized comparative interventional study that will be conducted on patients with large angle exotropia before and after doing surgical correction using three different surgical techniques including : 1/ bilateral lateral rectus muscle recession with unilateral medial rectus muscle resection 2/bilateral medial rectus muscle resection, 3/unilateral medial rectus muscle resection with lateral rectus muscle transplantation ,to compare the surgical outcomes between them.
Interventions
- Procedure Extropia squint surgery
patients with large angle exotropia will be treated by three different surgical techniques including: 1/ bilateral lateral rectus muscle recession with unilateral medial rectus muscle resection 2/bilateral medial rectus muscle resection, 3/unilateral medial rectus muscle resection with lateral rectus muscle transplantation ,to compare the surgical outcomes between them.
Primary outcome measures
- changes in ocular alignment [Time frame: at one month, 6 month and one year postoperatively.]
