目的：探讨被动牵拉试验在Yokoyama术中的作用。方法回顾分析3例（4眼）高度近视眼限制性内下斜视患者行Yokoyama术的临床资料。手术全程均行被动牵拉试验。结果4眼术前平均内斜视角度为118.75△，平均垂直斜视度15△，被动牵拉试验眼球外转、上转有限制。术后平均内斜视角度为10△，平均垂直斜视度2△，被动牵拉试验眼球外转、上转无限制。平均随访时间4.5月，术后情况保持稳定。结论在Yokoyama手术过程中全程采用被动牵拉试验，不但可以确定内直肌限制因素的强弱，还可以定量确定内直肌的后徙量。“,”Objective To investigate the effect of forced traction test in the Yokoyama’s surgery. Methods Retrospective analysis of records of 3 patients (4 eyes) with high myopic strabismus had done Yokoyama’s surgery. The forced traction test was applied through operation. Results The mean preoperative horizontal deviation of 4 eyes was 118.75△and mean vertical deviation was 15.00△, all patients had marked limitation of elevation and abduction by the forced traction test. After surgery,the mean horizontal deviation was 10△and mean vertical deviation was 2△, all patients had no marked limitation of elevation and abduction by the forced traction test. The average follow-up was 4.5 months, all patients achieved satisfactory results and remained stable. Conclusions The application of forced traction test in the Yokoyama’s surgery can not only determine the strength of the medial rectus muscle limiting factors, also can quantitatively determine the recessing amount of medial rectus muscle.
