In four patients with superior oblique palsy, symptomatic excyclotorsion was present without a substantial vertical deviation. Surgery of anteriorizing and lateralizing the anterior fibers of the superior oblique tendon on an adjustable suture was performed (adjustable Harada-Ito procedure). the morning after surgery, adjustment of the suture was made to eliminate the torsional deviation. The suture was loosened when an overcorrection was present and was tightened when an undercorrection was present. Follow-up varied from two to 20 months. All patients remained free of torsional symptoms and no vertical deviation was induced. In addition, the eyes operated on had no limitation of elevation in adduction. The technique allows the surgeon to more exactly adjust the advanced fibers of the superior oblique tendon so as to minimize or eliminate the excyclotorsion and eliminate symptomatic complaints.
在4例上斜肌麻痹患者中，存在症状性外旋转扭转但无明显垂直偏斜。采用可调节缝线对上斜肌腱前纤维进行前徙和外移手术（可调节的原田-伊藤手术）。术后次日清晨，调整缝线以消除扭转偏斜。出现过矫时放松缝线，出现欠矫时收紧缝线。随访时间为2至20个月。所有患者均无扭转症状，且未诱发垂直偏斜。此外，接受手术的眼睛在内收时上抬无受限。该技术使外科医生能够更精确地调整上斜肌腱的前移纤维，从而将外旋转扭转降至最低或消除，并消除症状性主诉。
