Aims: To report the surgical results of lateral rectus muscle (LR) recession, medial rectus muscle (MR) resection and fixation to nasal periosteum with superior oblique muscle tendon (SO) transposition in the restoration and maintenance of ocular alignment in primary position for patients with large-angle exotropia.

Methods: The medical records of patients who underwent surgery between 2009 and 2019 for large-angle exotropia treated with fixation to nasal periosteum with superior oblique (SO) transposition were reviewed. All patients underwent a preoperative assessment, including a detailed ophthalmologic examination.

Results: A total of 3 patients (age range, 14 - 48 years) with different etiologies were included. The median preoperative horizontal deviation was 95 Prism Diopter (PD) and no vertical deviation. The median postoperative horizontal residual exodeviation was 14 PD, and the vertical deviation was 8 PD in just one case. All cases were vertically and horizontal aligned within 10 PD and 20 PD of deviation, respectively.

Conclusion: Lateral rectus recession, medial rectus resection, and superior oblique transposition with nasal periosteum fixation could be used to obtain adequate anatomical and functional results in patients with large-angle exotropia, especially for patients with third nerve palsy.
