Surgical Management of Consecutive Exotropia: A Retrospective Analysis of Patient Outcomes

Objective: The aim of this study is to evaluate characteristics of consecutive exotropia(XT) patients in our clinics and to analyse our surgery outcomes.

 

Methods: Sixty-two eyes of 31 patients with consecutive XT who underwent previous strabismus surgeries were included in this retrospective study. Comprehensive ophthalmic examinations with refractive error after cycloplegia, convergence, and deviation angles were noted before and after surgery.    

 

Results: The mean age of all patients was 19.71±12.40 years, with a female-to-male ratio of 21/10 (68%). Nineteen of these patients had operation for consecutive XT(61%). Mean preoperative deviation angles at near and far were 31.30±10.70 and 32.50±10.20 PD, respectively. Of the patients who had operation for XT, 84% had convergence weakness. Bilateral or unilateral lateral rectus (LR) recession was performed in 5(26%) patients. Meanwhile, 2(11%) patients had medial rectus(MR) advancement; 2(11%) had MR advancement with additional resection; 3(16%) had MR advancement with resection + LR botulinum toxin injection; 6(31%) had MR advancement with resection + LR recession and 2(11%) had LR recession with Y split procedure. Mean postoperative deviation was -2.92±5.57 PD after one year (p<0.05). Four patients had more that one procedures for XT. The surgical success rate was 84% (n=16)(postoperative deviation of <10PD).No serious complications were noted.   

 

Conclusion: Consecutive XT might be addressed wih various surgical procedures. The surgical success rate after 1 year in our sample of patients was 84%.
