A Comparative Study Between Three Surgical Techniques in Large Angle Exotropia
- Conditions
- Exotropia Equal or More Than 50 Prism Diopter
- Registration Number
- NCT07143032
- Lead Sponsor
- Sohag University
- Brief Summary
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.
