目的:观察双眼外直肌后徙术治疗儿童类似分开过强型间歇性外斜视的手术疗效。方法回顾性分析行双眼外直肌后徙术治疗儿童类似分开过强型间歇性外斜视22例连续性病例的病历资料。采用三棱镜加交替遮盖法测量患儿,经1 h诊断性遮盖前后注视6 m及33 cm调节性视标第一眼位的斜视度。检查患儿的融合功能和立体视锐度。依据诊断性遮盖后测量的最大看远斜视度,行双眼外直肌对称性定量后徙术。术后1d、1个月、3个月、6个月检查患儿的斜视度和双眼视功能。疗效评价标准为斜视度≤±8 PD为正位。结果22例诊断性遮盖前看远与看近斜视度的差值为(17.3±7.9)PD,诊断性遮盖后看远与看近斜视度的差值为(0.5±3.3)PD。双眼外直肌后徙量(7.2±1.2)mm。术后平均随访(8.6±5.4)月。末次随访的正位率为81.8%(18/22)、过矫率为4.5%(1/22)、欠矫率为13.6%(3/22)。手术前后融合和立体视锐度的差异无统计学意义(P>0.05)。结论根据诊断性遮盖后测量的最大看远斜视度行双眼外直肌后徙术,可有效的矫正儿童类似分开过强型间歇性外斜视。“,”Objective To observe the surgical outcome of bilateral lateral rectus recession in children with simulated divergence excess intermittent exotropia.Methods Twenty-two children with simulated divergence excess intermittent exotropia underwent bilateral lateral rectus recession from December 2010 to August 2013 were recruited in this study. The exodeviations were measured by the alternate prism cover test at both distances (6 m and 33 cm)with fixation on accommodative targets before and after 1-hour diagnostic occlusion test.The Worth 4-Dot test was employed to assess central and peripheral fusion.The Titmus stereo test was used to assess stereoacuity.The target angle for the symmetri-cally quantitative bilateral lateral rectus recession was determined according to the largest distance deviation before or af-ter diagnostic occlusion test.The examinations were carried out on the first postoperative day,1 months,3months and 6 months later.A successful alignment was defined as ±8 PD or less in primary gaze while viewing distant and near targets.Results The average age of patients was 6.3 ±2.9 years.The disparity between distance deviation and near deviation before and after diagnostic occlusion test was 17.3 ±7.9 PD and 0.5 ±3.3 PD,respectively.The amount of bilateral lateral rectus recession was 7.2 ±1.2 mm.Mean postoperative follow-up period was 8.6 ±5.4 months.The successful rate,overcorrection rate,undercorrection rate at the end of follow-up was 81.8%(18 in 22),4.5%(1 in 22),13.6%(3 in22),respectively.There was no significant difference in fusion and stereoacuity before and after sur-gery (P>0.05).Conclusion Based on the largest distance deviation before and after diagnostic occlusion test,bilat-eral lateral rectus recession could effectively treat simulated divergence excess intermittent exotropia in children.
