| Summary: | Objectives: To present the outcomes of modified lateral rectus Y-splitting combined with either unilateral or bilateral horizontal rectus
recession in Duane Retraction Syndrome (DRS) with significant upshoot or downshoot.
Materials and Methods: A total of 12 patients including 10 patients with Type I DRS and 2 with Type III DRS underwent modified
Y-splitting surgery. Amount of additional recessions varied with the degree of preoperative deviation by intraoperative adjustable suture
technique. Preoperatively 3 patients had esotropia (ET), 6 had exotropia (XT), and 3 patients had orthotropia. The mean preoperative
deviation was 19.3 prism diopters (PD) (range, 18-20 PD) in ET patients and 19.2 PD (range, 16-20 PD) in XT patients.
Results: Postoperatively, all patients had significant correction in horizontal deviation and aligned within 4 PD of orthotropia, and
no patients exhibited abnormal head posture. Co-contraction and globe retraction were markedly reduced and abnormal ocular vertical
movement disappeared or significantly decreased in all cases. No patients experienced recurrence of ocular motility disorders in the mean
26-month (range, 13-66 months) follow-up period.
Conclusion: Modified Y-splitting surgery combined with co-contracting horizontal muscle recession technique seems to be a safe and
effective treatment in DRS. (Turk J Ophthalmol 2015; 45: 152-155) |
