Clinical features and surgical outcomes of Duane retraction syndrome in Turkish patients / 国际眼科杂志(Guoji Yanke Zazhi)

ABSTRACT

@#AIM: To analyze the clinical features and surgical outcomes of Duane retraction syndrome(DRS)patients.<p>METHODS: The clinical data of 94 DRS patients were evaluated. Complete ophthalmic data including age, sex, laterality, the type of DRS, angle of deviation, abnormal head posture(AHP), globe retraction, overshoots and the type of surgical approach were recorded.<p>RESULTS: The average age of patients was 15.4±9.18 years, and there were 78 males and 16 females. Unilateral and bilateral involvement were found in 87% and 13% of patients, respectively. In unilateral DRS patients, 65% left eyes predominance were observed. Of the 94 patients, 59.5% of the patients were type I, 29.7% of the patients were type II, 8.5% of the patients were type III and 2.1% of the patients were type IV. Most of the patients were 36(38%)esotropic and AHP over 10° was noted in 43(96%)patients, preoperatively. There were 40(43%)patients with overshoots which were more common in type II. Surgery was performed to 45(48%)patients.<p>CONCLUSION: An excellent surgical outcome was obtained in 32(78%)patients that underwent horizontal rectus surgery and AHP improved in 24(53%)patients. Y-splitting and posterior tenon fixation of lateral rectus both have satisfactory outcomes in the presence of significant overshoots. Foster augmentation with vertical rectus transposition achieved optimal results in abduction limitation.
