Surgical Outcome of Exotropic Patients' Management; One Year Follow-up

Purpose: To find the surgical success rate and frequency of complications among patients with exotropia.

Methods: This is a case series study on 102 exotropic patients who were managed surgically. They were followed up for 1 year post operation. Surgical techniques consisted one of the following bilateral rectus (BLR) recession, bimedial rectus (BMR) resection, Recession & resection (R&R), MR advancement and lateral rectus (LR) recession. Deviation measured by Alt. Prism- cover test at far and near. Data was analyzed by SPSS (ver. 16) using descriptive statistics and chi square test.

Results: Mean age of the patients was 18.2±11.4 years. Most cases were infants. Myopic astigmatism was the most frequent refractive error. The most frequent method of surgery was BLR recession in 75 cases (61.5%). Overall Post-operative success rate was 67.6%. The most frequent complication after surgery was misalignment.

Conclusion: BLR recession is a surgical method with acceptable success rate for treatment of exotropia and misalignment is most frequent complication.
