Abstract

Purpose: To study the efficacy and safety of Superior Rectus Transposition (SRT) in the treatment of Esotropic Duane syndrome. Methods: Medical records of patients with esotropic Duane syndrome who underwent SRT with Medial Rectus Recession (MRc) between July 2015 and December 2022 were reviewed. Results: There were twelve eyes (10 patients) of Esotropic Duane syndrome who underwent SRT combined with 5.5 mm MRc. The mean preoperative deviation was 21 PD (15 PD – 30 PD) and the mean postoperative deviation was 6 PD (0 – 10PD). Abduction improved in 9 patients, from -3.5 (-5 to -3) to –2.6 (-3 to -2). There was no improvement in abduction in 3 patients. One patient developed 8 PD hypertropia and diplopia, which resolved spontaneously in a month time. Conclusion: SRT with MRc was effective in improving abduction, esotropia and compensatory head posture but it has risk of inducing hypertropia causing diplopia.
