摘要
目的探讨《近视眼的成因与防治进展》中提出的防近新方法并验证实际效果,为改善中小学生近视现状提供依据。方法在郑州市10所防近试点学校中,选取配合度较好的2所初中、3所小学,每校在指定年级各随机选取2个班共678名学生为实验组;在每校相同年级中再选取成绩与实验组相当的各2个班,共658名学生为对照组1;在数学水平相当的非试点学校中随机选取2所初中、3所小学,每校随机选取与实验组同年级学生各2个班,共675名学生为对照组2。主要运用降眼压操和戴凸透镜等防近新方法进行应用性研究。结果实验后,初中实验组、对照组1、对照组2的视力不良率上升幅度分别为1.62%,3.24%,13.10%,远视力下降率分别为40.65%,58.95%,83.84%。小学实验组、对照组1、对照组2的视力不良率上升幅度分别为5.32%,9.98%,13.90%,远视力下降率分别为31.25%,48.18%,59.19%。单一防近方法(40.00%)和复合防近方法(19.42%)视力下降率差异有统计学意义(P<0.01)。结论防近新方法对中小学生均具有良好的防控效果,防近效果最好的方法是降眼压操配合戴凸透镜。
Objective To verify the actual results of new methods of myopia prevention and control in The Progress of My- opia Causes and Prevention. Methods Selected 2 secondary schools and 3 primary schools in pilot schools, and designated two classes each of 5 schools, a total of 678 students which were as the experimental groups ; and selected randomly 2 classes in each of the selected five pilot schools, together 658 students as the first control groups ; selected 2 middle schools and 3 primary schools in non-pilot schools at the same level in teaching, and randomly selected two classes in each of 5 non-pilot schools, a total of 675 students were the second control groups. Results After the experiment, margins of poor vision rates of the experimental group, the first control group and the second control group were separately 1.62% , 3.24% and 13.10%. And the decreased rates of distant vision were 40.65% , 58.95% and 83.84% , respectively. Primary schools： The increased rates of poor vision in the experimental group, the first control group and the second control group were apart 5.32% , 9.98% and 13.90%. The decreased incidences of distant vision were 31.25% , 48.18% and 59.19% , respectively. The difference of the rates of decreased vision between the unity preventing methods for myopia（40.00% ） and the complex methods to prevent myopia （ 19.42% ） was statistically significant（P 〈 0.01 ）. Conclusion New methods to prevent myopia for primary and secondary students have a good prevention and control effect. And the best method of preventing myopia is the method of antiglaueoma operation with wearing lens.
