目的：观察水平肌肉移位术对间歇性外斜视合并小度数垂直斜视的矫正效果。 方法：总结7例9眼间歇性外斜视伴小度数垂直斜视的病例，手术矫正水平斜视的同时，对水平肌肉止端垂直移位，矫正并存的小度数垂直斜视；术后随访3~18（平均6）mo，观察其疗效。 结果：水平斜视矫正的同时，垂直眼位也得到满意矫正，5例7眼患者垂直眼位消失，1例1眼患者术后由R/L8^△变成R/L2^△，1例1眼患者术后由原来R/L6^△变成L/R2^△。随访期间全部患者均未出现医源性A-V现象，无复视，无代偿头位。 结论：在解决水平斜的同时进行水平肌肉垂直移位可兼顾到小度数垂直斜的矫正。"

AIM:To observe the therapeutic effect of vertical displacement of horizontal recti for horizontal strabismus accompanied by micro-degree vertical strabismus． METHODS: Seven patients (9 eyes) who suffered from horizontal strabismus accompanied by micro-degree vertical strabismus were studied retrospectively．All patients were treated with lateral or medial rectus resection or recession and vertical displacement of these muscles．Follow-up lasted for 3-18(mean 6) months to observe its effect. RESULTS:All cases had a good correction with surgery.Of 5 patients (7 eyes), the vertical strabismus was 0^△. After the operation 1 patient (1 eye) had the by R/L8^△ turned into R/L2^△，1 patient had the by R/L6^△ into L/R2^△.During the follow-up period all patients did not present iatrogenic A-V phenomenon, diplopia, or compensatory head posture. CONCLUSION:Vertical displacement of horizontal recti is successful for horizontal strabismus accompanied by micro-degree vertical strabismus .
