Abstract

Background: Strabismus surgery aims to improve the ocular alignment of the visual axis & the cosmetic appearance of studied cases with strabismus. The most common functional benefits are the restoration of binocular vision, with the elimination of diplopia & compensatory head posture.In cases of large-angle exotropia, many surgical methods have been performed, bilateral lateral rectus recession, medial rectus resection with lateral rectus recession are most frequently used. Aim: To evaluate outcome of supermaximal monocular recession-resection versus large bilateral lateral rectus recession in large angle exotropia. Patient & Methods: This was a prospective, interventional, nonrandomized study. This study was done at Ophthalmology department AL zahraa university hospital, Cairo, Egypt, in the duration from May, 2021 to May, 2022 and included (20) patients, they were divided into 2 groups: group A (10) who underwent monocular recession- resection operation in large angle exotropia and group B (10) patients who underwent bilateral lateral rectus recession operation in large angle exotropia. Results: At the final examination, In the RR group, 7 of 10 studied cases (70%) were successfully aligned and 3 (30%) had recurrence. In the BLR group 8 (80%) of 10 studied cases achieved successful alignment, 2 (20%) had recurrence. Successful alignment & recurrence rates were not significantly different between the groups. Conclusion: The successful alignment rate of 2-muscle surgery in patient with large angle exotropia was 75% & the overall surgical results were comparable between BLR & RR groups.
