Summary
For large-angle sensory exotropia, supermaximal muscle surgery on the visually poor eye is a feasible option. This approach avoids operating on the seeing eye, offering a safe and effective treatment for exotropia patients.
Area of Science:
- Ophthalmology
- Strabismus Surgery
Background:
- Large-angle exotropia, especially sensory exotropia, presents surgical challenges.
- Traditional 3- or 4-muscle surgery may be contraindicated in patients with a single seeing eye.
Observation:
- This study focused on 4 adult patients with sensory exotropia and large deviation angles (mean 82.3 PD).
- Surgery was performed exclusively on the visually poorer eye, involving medial rectus resection and lateral rectus recession.
Findings:
- The surgical intervention resulted in a significant reduction in exodeviation, with a mean postoperative angle of 2.0 PD.
- No disfiguring side effects, such as limited abduction, palpebral fissure narrowing, or enophthalmos, were observed.
Implications:
- Supermaximal resection and recession on the visually poor eye is a clinically viable surgical strategy for large-angle sensory exotropia.
- This monocular approach effectively corrects significant exodeviation while preserving the function and aesthetics of the seeing eye.
