Comparison of Long-term Surgical Outcomes of 2-muscle Surgery in Children With Large-angle Exotropia: Bilateral vs Unilateral

The long-term successful alignment rate of 2-muscle surgery in children with primary large-angle exotropia was 64%, and the overall surgical outcomes were comparable between the BLR and RR groups. However, in patients with exotropia of ≥45 PD, the unilateral recess/resect procedure resulted in more favorable long-term outcomes.
