摘　　要：[目的 ]　用眼屈光度作为指标评价个体儿童近视眼易患性 ,开展早期预防。 [方法 ]　对 6～ 14岁 6 6 5名学生眼屈光度进行一年追踪检测 ,应用远视屈光度下降值研制学生近视眼屈光阈值。 [结果 ]　儿童近视眼屈光阈值随年龄增长而下降 ,6、7岁组阈值为 + 2 .0 0 D,8～ 13岁各年龄组均以 0 .2 5 D的级差递减 ,14岁组为 + 0 .37D。 [结论 ]　研制的阈值为学生近视眼预测提供了判断界值。通过预测 ,可及早发现近视眼易患者 ,有利于近视眼早期预防 。Objective] To evaluate the liability of myopia in child with diopter as a indicator and prevent myopia earlier.[Methods] Diopter were followed up to study during one year in 665 children aged 6～14 years. The refractive thresholds of myopia were developed with decreasing value of hypermetropic diopter.[Results] The refractive thresholds of myopia in children decrease with age increasing. Both 6 and 7 years old are +2.00D.From 8 to 13 years old, each group decreases 0.25D. The 14-year-old group is +0.37D.[Conclusion] It has applied a evaluation value for forecasting myopia among children in different age group. It is useful for discovering liability of myopia and preventing myopia earlier.
