Outcomes for Intermittent Exotropia Using Three Common Surgical Approaches
Journal of Pediatric Ophthalmology and Strabismus
|March 14, 2024
Summary
Bilateral lateral rectus recession (BLR) and unilateral lateral rectus recession with medial rectus resection (RR) are effective for intermittent exotropia. Unilateral lateral rectus recession with medial rectus plication (RP) resulted in a larger exodeviation angle post-surgery.
Area of Science:
- Ophthalmology
- Strabismus Surgery
Background:
- Intermittent exotropia is a common form of strabismus.
- Surgical correction aims to improve ocular alignment and binocular function.
Purpose of the Study:
- To compare surgical outcomes for intermittent exotropia using three techniques: bilateral lateral rectus recession (BLR), unilateral lateral rectus recession and medial rectus resection (RR), and unilateral lateral rectus recession and medial rectus plication (RP).
Main Methods:
- Retrospective review of 123 patients undergoing surgery for basic intermittent exotropia between 2015-2023.
- Patients were stratified into BLR, RR, or RP groups.
- Postoperative alignment was assessed at 1 year.
Main Results:
- The unilateral lateral rectus recession with medial rectus plication (RP) group showed a significantly larger angle of exodeviation compared to BLR and RR groups at 1 year (P = .03).
- No significant difference in outcomes was found between the BLR and RR groups (P = .57).
Conclusions:
- Both BLR and RR are equally effective surgical approaches for treating intermittent exotropia.
- RP is less effective, resulting in a larger residual exodeviation compared to BLR and RR.
