A retrospective study was conducted to compare the efficacy of medial rectus recession and lateral rectus resection as surgical interventions for divergence insufficiency in 18 patients. These were cases of non-neurological cause. Two patients in each group required postoperative adjustment. Of nine patients in the medial rectus group, no patient had reoperation for diplopia but one required prisms. Of nine patients in the lateral rectus group, no patient had reoperation for diplopia but three developed distance esotropia requiring prisms or exercises and one developed near exophoria requiring exercises. Both methods were found to be effective in reducing symptoms and the near / distance deviation disparity.
