Summary
Adjustable and non-adjustable hang-back muscle recession surgery for concomitant exotropia showed similar success rates. Non-adjustable recession is a viable option for routine strabismus surgery.
Area of Science:
- Ophthalmology
- Surgical Techniques
- Strabismus Surgery
Background:
- Concomitant exotropia is a common form of strabismus.
- Surgical management aims to restore ocular alignment.
- Adjustable and non-adjustable techniques are used for muscle recession.
Purpose of the Study:
- To compare the efficacy of adjustable versus non-adjustable hang-back muscle recession for concomitant exotropia.
- To evaluate long-term ocular alignment outcomes after strabismus surgery.
Main Methods:
- A comparative study involving 38 patients with concomitant exotropia.
- Patients underwent either adjustable or non-adjustable hang-back muscle recession.
- Groups were matched for age, deviation type and amount, and surgical details.
Main Results:
- At 6 months, 95% of adjustable and 90% of non-adjustable groups achieved alignment within 10 prism diopters (PD).
- At mean 3.4 years follow-up, 92% of adjustable and 86% of non-adjustable groups maintained alignment within 10 PD.
- No statistically significant difference in success rates was observed between the groups.
Conclusions:
- Both adjustable and non-adjustable hang-back muscle recession techniques yield comparable success rates for concomitant exotropia.
- Non-adjustable hang-back muscle recession is a suitable alternative for routine surgical correction of concomitant exotropia.
