摘　　要：目的探索伴有下斜肌亢进的分离性垂直偏斜的有效手术方式。方法对54例95眼伴有下斜肌亢进的DVD患者应用下斜肌后徒转位法。依据上斜程度确定下斜肌新附着点的位置。上斜小于6△16眼转位到下直肌止端水平后1mm;上斜7～11△45眼,转位到下直肌止端水平;上斜大于11△34眼,前移到下直肌止端前1mm或2mm(1mm25眼,2mm9眼)其中1例单眼上斜50～80△者联合同侧上直肌后徙6mm,对合并水平斜视者,则采用水平直肌后徙和缩短术同时矫正水平斜视。结果术后满意者93眼(97.89%),好转者2眼(2.11%),无1例无效者。95眼术后下斜肌亢进均消失,无1例上转受限者。结论下斜肌后徒转位术是治疗伴有下斜肌亢进分离性垂直斜视的有效手术方式。Objective To discuss the effetive surgery measures of dissociated vertical deviation （DVD） with overaction of inferior oblique muscle （10）. Methods Anterior displacement of IO insertion was applied to 54 cases （95 eyes） of DVD with overaction of IO. The new insertion of IO was decided by the degree of hypertropia. In 16 eyes with hypertropia〈6^△ , IO was displaced to 1mm laterally behind the insertion of the inferior rectus OR）. In 45 eyes with hypertropia 7-11^△, IO was displaced to the insertion of IR. In 34 eyes with hypertropia〉12^△, IO was displaced to lmm or 2mm （1mm 25eyes, 2mm 9eyes） previous the insertion of IR. In one case with hypertropia 50-80^△ IO displacement was combined with suprior rectus recession 6ram. For those combined with horizontal strabismus, the horizontal deviation was corrected together. Results In 95 eyes 93 got satisfied resuhs（97.89%）. 2 eyes got improvement（2.11%）. Overaction of IO was eliminated in all cases. Condution Anterior displacement of IO is an effective method for DVD with overaction of IO.
