Comparative study of bilateral rectus hang-back recession versus unilateral recession-resection for management of large-angle basic intermittent exotropia in Egyptian children

Purpose The aim of this study was to compare the efficacy of lateral rectus recession-medial rectus resection (R-R) and bilateral rectus recession (BLR) for the management of large-angle basic intermittent exotropia (IXT) in Egyptian children. Patients and methods One-hundred patients with basic IXT were included in the study. They were divided into two groups: group A underwent R-R, and group B underwent BLR. All patients were subjected to a complete ophthalmological examination, including measuring the angles of deviation at distant and near. They were followed up at 1 day, 1 week, 1 month, 3 months, and 6 months postoperatively. Results At the end of the follow-up period, the R-R group showed a success rate of 62%, whereas the BLR group showed a success rate of 64%. The effect of both techniques was similar on the distant angle of deviation, which was 6.4±4.3 for group A and 4.0±6.9 for group B postoperatively. In addition, the postoperative near angle of deviation was 5.4±2.3 for group A and 3.0±8.2 for group B, with no statistically significant difference between the two groups (P>0.05). Conclusion The two surgical procedures were comparable in the management of large-angle basic IXT.
