Summary
True muscle transplantation effectively corrects large-angle strabismus (eye misalignment) using a two-muscle approach. This surgical technique offers a safe and predictable solution for achieving satisfactory cosmetic alignment.
Area of Science:
- Ophthalmology
- Surgical Innovation
- Strabismus Treatment
Background:
- Large-angle strabismus frequently requires multiple surgical interventions for alignment.
- Patients often exhibit reluctance towards bilateral surgeries for strabismus correction.
Observation:
- A novel technique, true muscle transplantation, was employed in three patients with large-angle esotropia.
- This method involved elongating the medial rectus muscle using a fragment of resected extraocular muscle.
Findings:
- Postoperative deviation was within +/- 10 prism diopters (PD) of orthophoria, indicating successful alignment.
- The achieved alignment remained stable during 6- to 12-month follow-ups.
- Mild underaction of the surgically manipulated muscle was observed postoperatively.
Implications:
- True muscle transplantation presents a viable alternative for correcting large-angle strabismus.
- It enables significant strabismus correction through a two-muscle surgical procedure.
- The technique demonstrates safety, predictability, and satisfactory cosmetic outcomes in patients with complex strabismus.
