目的：我们着手确定弱视遮盖治疗依从性低（电子测量）的儿童是否是视力增加不足的儿童。研究方法：在14名新发现的弱视儿童（平均年龄4.3 ± 1.9岁）中，在开始遮盖治疗后6个月，在1周内以电子方式测量依从性。使用闭塞剂量监测器（ODM）测量顺应性。在计划的辅助访视期间进行测量。屈光参差5例，斜视4例，屈光参差伴斜视5例。依从性以电子注册时间与规定闭塞时间的百分比表示。在达到以下任何标准时定义6个月遮盖治疗后的令人满意的视力增加：视力增加表示为弱视眼的视力与好眼的视力之间的比率大于0.75，在E-Chart或Landolt-C上测量的弱视眼的视力超过0.5，或视力增加三条LogMAR线。结果如下：测量的依从性平均为80%的8名儿童谁有一个令人满意的视力增加和34%的6名儿童谁有一个不满意的视力增加。低敏度增加的儿童具有统计学显著性较低的依从性（P=0.038）。结论：矫正医师的一般假设，即视力增加不足的儿童对弱视遮盖治疗的依从性较低，已经通过电子客观手段得到验证。
Purpose: We set out to determine whether the children who have low compliance (measured electronically) with occlusion therapy for amblyopia are those with insufficient increase of visual acuity. Methods: In 14 newly identified amblyopic children (mean age 4.3+/-1.9 years), compliance was measured electronically over a period of I week, 6 months after the start of occlusion therapy. Compliance was measured with an Occlusion Dose Monitor (ODM). The measurements took place during planned domiciliary visits. The children were diagnosed with anisometropia (n=5), strabismus (n=4) and anisometropia and strabismus (n=5). Compliance was expressed in percentages of the electronically registered time compared with the prescribed occlusion time. Satisfactory acuity increase following 6 months of occlusion therapy was defined on reaching any of the following criteria: acuity increase expressed as a ratio between acuity of the amblyopic eye and acuity of the good eye of more than 0.75, acuity of the amblyopic eye exceeding 0.5 as measured on the E-Chart or Landolt-C, or three LogMAR lines of increase in acuity. Results: Measured compliance averaged 80% in the eight children who had a satisfactory acuity increase and 34% in the six children who had an unsatisfactory visual acuity increase. Children with low acuity increase had statistically significantly lower compliance (P=0.038). Conclusion: The general assumption among orthoptists, that compliance with occlusion therapy for amblyopia is low in children with insufficient acuity increase, has been validated by electronic, objective means.
