Methods(1)4 cities were chosen randomly according to their economic status and geographical location.(2)An autorefractor was used to detect the diopter in the preschool children from 20 kindergartens randomly selected from each of the 4 cities.(3)1%atropine ointment was applied to the c onjunctival sac of the children with suspect myopia for 3 days and the refractio n of light in their retina was then examined by a barred beam skiascope.(4)The eye axis and corneal curvature of the myopic children were measured.(5)The diop ter,eye axis,and corneal curvature were examined every 6 months during 1-year f ollow-up after the diopter was properly rectified.

(1)依经济状况和地理位置按随机原则抽取4市县；(2)从4市县中各随机选择20间幼儿园，对所抽取的在园学龄前儿童用自动屈光仪进行屈光筛查；(3)可疑近视患者予以1%阿托品眼膏涂双眼3d，由专人用带状检影镜进行视网膜检影验光；(4)确诊为近视的患者自愿进行角膜曲率和眼轴测量；(5)近视患者经适当的屈光矫正后，按要求进行为期1年的前瞻性随访，每半年进行1次屈光状态、角膜曲率和眼轴的检测。
