Summary
This study shows that combined adjustable suture surgery effectively treats incomitant strabismus, significantly reducing eye misalignment and eliminating double vision in most patients. The procedure is simple and beneficial for specific cases.
Area of Science:
- Ophthalmology
- Strabismus Surgery
Background:
- Patients with incomitant strabismus may be asymptomatic in primary gaze but experience diplopia in secondary gaze positions.
- This subset of patients presents a unique challenge for surgical correction.
Purpose of the Study:
- To evaluate the efficacy of a combined adjustable suture resection and recession procedure.
- To assess the outcomes for rectus extraocular muscles in patients with specific strabismus patterns.
Main Methods:
- Retrospective chart review of 12 patients.
- Surgical technique involved combined resection and recession of the same rectus extraocular muscle using adjustable sutures.
- Recession amount was double the resection amount.
Main Results:
- Preoperative mean incomitance of 11.6 prism diopters (PD) reduced to 2.9 PD postoperatively.
- Diplopia was resolved in 11 out of 12 patients.
- No significant change in primary position alignment was observed.
Conclusions:
- Combined adjustable suture resection and recession is an effective and straightforward surgical option.
- This procedure successfully addresses incomitant strabismus in the studied patient group.
