Purpose
To compare two different modalities of superior rectus–lateral rectus loop myopexy; suture (SLM) and silicone band loop (SBM), in the treatment of myopic strabismus fixus.
Methods
The medical records of patients with myopic strabismus fixus who underwent surgical management with either SLM or SBM at a single institution over a period of 4 years were retrospectively reviewed. In cases with positive intraoperative forced duction test, the medial rectus muscle was recessed. The primary outcome measures were improvement of primary position esotropia, hypotropia, and limitations of abduction and elevation. The angle between the displaced superior rectus and lateral rectus muscles (angle of globe dislocation) was also assessed by orbital imaging before and after surgery.
Results
A total of 21 patients were identified, of whom 10 underwent SLM and 11 underwent SBM. Mean age at surgery was 65.4 ± 5.7 …
