Results of Augmented Bimedial Rectus Recessions in the Treatment of Large-Angle Esotropia

Pur po se: To evaluate the surgical results of augmented bimedial rectus recession in large-angle esotropia (ET).\udMa te ri al and Met hod: The records of forty-nine patients (26 male, 23 female) who underwent 6 mm and more bimedial rectus recession\udfor large-angle deviation were reviewed. The mean follow-up period was 18.43±22.12 (between 3 and 84) months. The average of\uddistance and near deviation amount was recorded in the postoperative 1st week and at the last visit as prism diopter (PD). Nineteen\udpatients whose follow-up periods were longer than 1 year (mean: 40.74±20.94 months) were evaluated as a different group. Success and\udreoperation rates of both groups were assessed.\udRe sults: The mean age of the 49 patients was 7.04±8.77 (range from 1 to 67) years and the mean preoperative esodeviation amount\udwas 49.8±11.9 (range from 35 to 85) PD. In the postoperative 1st week, the average deviation was 10.67±8.65 PD and success rate\udwas found to be 61.1%, and in the last visit, the mean deviation angle was 9.82±9.24 PD and the success rate was 67.3%. Five of the\udcases (10.2%) needed reoperation. The mean age of the 19 patients with follow-up period longer than 1 year was 4.57±4.39 years\ud(ranged between 1 and 17), and the mean preoperative esodeviation angle was 44.21±6.07 (ranged between 35 and 55) PD. In the\udgroup with longer follow-up period, the postoperative average deviation amount and success rate were 8.58±8.23 PD and 68.4% in\udthe 1st week, and 8.05±8.02 PD and 73.7% in the last visit. Reoperation rate was found to be 21.05% (4 cases) in this group.\udDis cus si on: Although augmented bimedial recession technique for the correction of large-angle ET gives good results in short periods, additional\udsurgeries may be needed after longer follow-up periods.
