1. Conclusion All the hypermetropia children must use atropine. 结论儿童诊断性验光必须使用阿托品。
2. Objective: To investigate the rules of refractive changes in children with hypermetropia. 目的：探讨儿童远视眼的屈光演变规律。
3. With age increasing, the diopter of these subjects had a tendency of hypermetropia from myopia. 随着年龄的增长，人眼的屈光度有由近视向远视变化的趋势。
4. Methods Hypermetropia and myopia were induced by playing concave and convex lens in front of eyes of 32 subjects. 方法在正常眼前放置正、负球镜，人工诱导单纯性远视、近视性屈光参差。
5. But there was significant difference in the average annual reduction of hypermetropia among the groups of low, middle and high powers of hypermetropia. 轻度、中度、高度远视眼，远视平均每年降低的幅度比较，差异有高度显著性。
