Abstract

To analyse and compare the outcome of two different surgical procedures in patients with complete third nerve palsy with large angle exotropia.
This is a retrospective analysis of 35 patients with total third nerve palsy and large angle exotropia from January 2006 to June 2020 who underwent either of these two surgical procedures.
Group 1: Lateral rectus deactivation with medial rectus resection.
Group 2: Lateral rectus deactivation with medial rectus fixation to medial palpebral ligament (MPL).
Surgical alignment on the first post-operative day, and at 1 and 6 months postoperatively, were analysed, with postoperative complications. All statistical analyses were performed using STATA version 14 and P value <0.05 was considered significant.
Surgical success was greater with group 2 (93.33%) than group 1 (65%). Postoperative exotropic drifts were noted in both the procedures but seen more with patients in Group 1. However, postoperative complications were noted only in Group 2 patients.
