PURPOSE
We wanted to examine the effect of graded recession and anteriorization of the inferior oblique muscle on patients suffering from unilateral superior oblique palsy.
METHODS
Inferior oblique muscle graded recession and anteriorization were performed on twenty-two patients (22 eyes) with unilateral superior oblique palsy. The recession and anteriorization were matched to the degree of inferior oblique overaction and hypertropia. The inferior oblique muscle was attached 4 mm posterior to the temporal border of the inferior rectus muscle in six eyes, 3 mm posterior in five eyes, 2 mm posterior in five eyes, 1 mm posterior in five eyes, and parallel to the temporal border in one eye.
RESULTS
The average angle of vertical deviation prior to surgery was 11.3 +/- 3.9 prism diopters (PD). The total average correction in the angle of vertical deviation after surgery was 10.8 +/- 3.8 PD. In the parallel group, the average reduction was 14 PD. After surgery, normal inferior oblique muscle action was seen in eighteen of twenty-two eyes (81.8%).
CONCLUSIONS
Graded recession and anteriorization of the inferior oblique muscle is thought to be an effective surgical method to treat unilateral superior oblique palsy of less than 15 PD.
目的
我们想要研究下斜肌分级后徙术和前徙术对单侧上斜肌麻痹患者的影响。
方法
对22例（22眼）单侧上斜肌麻痹患者施行下斜肌分级后徙术和前徙术。后徙和前徙的程度与下斜肌亢进及上斜视的程度相匹配。6眼将下斜肌附着于下直肌颞侧缘后方4mm处，5眼附着于后方3mm处，5眼附着于后方2mm处，5眼附着于后方1mm处，1眼与颞侧缘平行。
结果
术前垂直斜视平均角度为11.3±3.9三棱镜度（PD）。术后垂直斜视角度的总平均矫正量为10.8±3.8PD。在平行组，平均减少量为14PD。术后，22眼中有18眼（81.8%）下斜肌动作正常。
结论
下斜肌分级后徙术和前徙术被认为是治疗小于15PD的单侧上斜肌麻痹的一种有效手术方法。
