红色视力表远距离视功能训练在近视性弱视治疗中的疗效分析

目的：对比观察分析红色视力表远距离视功能训练在近视性弱视治疗中的疗效。方法近视性弱视患儿甲、乙两组共112例212眼，甲组62例117眼，年龄4-12岁（5.71±1.78岁），乙组50例95眼，年龄3-12岁（5.96±1.83岁）；其中甲组轻度、中度、高度近视眼分别为21眼（17.95%）、67眼（57.26%）、29眼（24.79%），乙组为18眼（18.95%）、55眼（57.89%）、22眼（23.16%）（χ2＝0.09，P〉0.05）；甲组轻度、中度、重度弱视眼分别为30眼（23.15%）、64眼（54.70%）、23眼（19.66%）；乙组为24眼（25.26%）、54眼（56.84%）、17眼（17.89%）（χ2＝0.133，P〉0.05）；甲组病例采用短小遮盖＋近距离视功能训练；乙组病例采用短小遮盖＋红色视力表远距离视功能训练，所有病例治疗随访时间17个月，对比分析两种治疗方法在近视性弱视治疗中的疗效。结果甲组基本治愈率为39.32%，有效率为43.59%，无效率为17.09%；乙组基本治愈率为47.37%，有效率为36.84%，无效率为15.79%，统计学检验差异无显著性（χ2＝1.434，P〉0.05）；甲乙两组治疗后轻、中、高度近视眼数分别为：4眼（3.42%）、65眼（55.56%）、48眼（41.03%）和5眼（5.26%）、67眼（70.53%）、23眼（24.21%）统计学检验差异有显著性（χ2＝6.734，P〈0.05）。结论红色视力表远距离视功能训练治疗近视性弱视疗效好，同时能更好的减少治疗后弱视眼近视度数的发展。

The effect of distance visual training through reading red visual acuity chart in children with myopic ambly- opia

To observe effect of visual distance training by reading the distance red E standard log-arithm visual acuity chart in children with myopic amblyopia. Methods 112 children （212eyes） with myopic amblyopia were treated, 62 children （117eyes） in Group A aged 4-12y（5.71±1.78y） were treated with minimal occlusion＋ training near activity and 50 children （95eyes） in Group B aged 3-12y（5.96±1.83y） were treated with minimal occlusion＋ read-ing the distance red E standard logarithm visual acuity chart. The patients with mild myopia, moderate myopia and high myopia were 21, 67 and 29eyes in group A and 18, 55 and 22 eyes in group B（χ2=0.09 , P〉0.05）.The patients with low amblyopia, medium amblyopia and severe amblyopia were 30, 64 and 23 eyes in group A and 24, 54 and 17 eyes in group B （χ2=0.133 , P〉0.05）. All patients were followed up 17 months. To observe the clinical effect of the two different combined therapy. Results The recovery rate, effective rate and inefficacy rate was 39.32%, 43.59%, 17.09%, respectively in Group A. and 47.37%, 36.84%, 15.79%, respectively in Group B （χ2=1.434 , P〉0.05）;The patients with mild myopia, moderate myopia and high myopia were 4, 65 and 48 eyes in group A and 5, 67 and 23 eyes in group B after therapy （χ2=6.734 , P〈0.05）, Conclusions There are a equal effect for reading the distance red E standard logarithm visual acuity chart and near activ-ity in treating myopic amblyopia children and the de-velop of myopic degree were mild for distance activity fter therapy.
