目的:探讨伴有下斜肌功能亢进的分离性垂直斜视(disso-ciated vertical deviation,DVD)的临床特征,分析改良的下斜肌前转位术治疗伴有下斜肌功能亢进的DVD的疗效。方法:手术治疗伴有下斜肌功能亢进的DVD48例。将下斜肌离断,然后转位固定于下直肌止端颞侧1mm后1mm处。术后随访2wk～12mo。结果:下斜肌转位术对小度数DVD组和中等度数DVD组的原在位垂直斜度的矫正效果无显著性差异,小度数DVD组和中等度数DVD组与大度数DVD组在原在位垂直斜度的矫正效果有显著性差异。结论:改良的下斜肌前转位术治疗伴有下斜肌功能亢进的垂直分离性斜视安全有效。

AIM:To study the clinical characteristics of dissociated vertical deviation with inferior oblique muscles hyperfunction,and analyze clinical effects on the surgical treatment with superior inferior oblique muscles anterior transposition. METHODS:Forty-eight patients of dissociated vertical deviation with inferior oblique hyperfunction were treated by superior inferior oblique muscles anterior transposition.Breaking and fixing inferior oblique muscles at the temporal rectus inferior 1mm and under rectus inferior 1mm. Following-up was from 2 weeks to 12 months. RESULTS:The correction in the vertical strabismus angle had no singnificant difference between small degree group with moderate degree group.However,the correction in the vertical strabismus angle had a singnificant difference between small and moderate degree group with large degree group. CONCLUSION:The surgical treatment with superior inferior oblique muscles anterior transposition is safe and effective.
