Purpose:
To evaluate the surgical results of augmented bimedial rectus recession in large-angle esotropia (ET).
Material and Method:
The records of forty-nine patients (26 male, 23 female) who underwent 6 mm and more bimedial rectus recession for large-angle deviation were reviewed. The mean follow-up period was 18.43±22.12 (between 3 and 84) months. The average of distance and near deviation amount was recorded in the postoperative 1st week and at the last visit as prism diopter (PD). Nineteen patients whose follow-up periods were longer than 1 year (mean: 40.74±20.94 months) were evaluated as a different group. Success and reoperation rates of both groups were assessed.
Results:
The mean age of the 49 patients was 7.04±8.77 (range from 1 to 67) years and the mean preoperative esodeviation amount was 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 was 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 cases (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 (ranged between 1 and 17), and the mean preoperative esodeviation angle was 44.21±6.07 (ranged between 35 and 55) PD. In the group with longer follow-up period, the postoperative average deviation amount and success rate were 8.58±8.23 PD and 68.4% in the 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.
Discussion:
Although augmented bimedial recession technique for the correction of large-angle ET gives good results in short periods, additional surgeries may be needed after longer follow-up periods. (Turk J Ophthalmol 2011; 41: 314-7)
