外斜V征的手术探讨

目的:探讨外斜V征的手术方法及效果。方法:分析我院2004-01/2008-12收治27例外斜V征患者的手术方法及效果。27例患者中,根据发病原因采取不同的手术方式。18例伴有下斜肌功能亢进的外斜V征患者行下斜肌减弱+外斜视矫正术;9例无下斜肌功能亢进的患者在矫正外斜视的同时行水平肌垂直移位。随访2～41mo。结果:患者27例中25例V征消失;第一眼位正位者24例,欠矫2例,过矫1例;15例患者具有不同程度双眼视功能,其中2例恢复立体视。结论:下斜肌功能亢进是外斜V征发病的主要原因,下斜肌减弱联合外斜视矫正术是有效的治疗方法;对于无下斜肌功能亢进者,在矫正外斜视的同时行水平肌垂直移位也具有确切的效果。

Exploration of operative methods in V-pattern exotropia

AIM:To explore the operative methods and post-operative effects of V-pattern exotropia. METHODS:The operative methods and postoperative effects of 27 cases with V-pattern exotropia treated in our department during January 2004 to December 2008 were analyzed. Operative methods were chosen on the basis of their cause. 18 cases with inferior oblique hyperfunction were treated with inferior oblique reduction and exotropia correction. 9 cases without inferior oblique hyperfunction were treated with inferior oblique reduction and horizontal rectus vertical transporting. Follow-up time after surgey was two months to forty-one months.RESULTS:Twenty-five cases got V sign corrected,24 cases returned to the normal at primary position of eye,2 cases had undercorrection,1 case had overcorrection. 15 cases got different degrees of binocular vision,2 cases got stereoscopic vision. CONCLUSION:Inferior oblique hyperfunction is the main cause of V-pattern exotropia. Inferior oblique reduction and exotropia correction are effective methods. Patients without inferior oblique hyperfunction can be treated effectively with inferior oblique reduction and horizontal rectus vertical transporting.
