摘　　要：目的了解普通学校小学生视力不良情况和屈光状态及其与近视发生发展的关系。方法调查沈阳市铁西区一小学636名小学生的远视力，其中230名（459只眼）视力不良学生进行散瞳验光，判断屈光状态，将所得结果比较分析。结果视力不良发生率为36．08％，各年级近视眼发病率差异有统计学意义，女生发生率高于男生，视力下降的程度也随学年的升高差异明显加重。屈光不正中低年级以远视为主，高年级以近视为主。远视性屈光不正的患病率随学年升高而下降，近视性屈光不正患病率则随学年升高逐渐增加。结论引起小学生视力下降的主要原因是近视，做好近视防治工作，对控制小学生视力不良有重要意义。Objective To investigate the primary students＇ visual acuity and refractive status and the correlation between them. Methods Distant visual acuity was investigated among 636 students in Shenyang area. Two hundred and thirty students （459eyes） withametropia were enrolled as the subjects and the refractive status was determined by cyclopedm retinoscopy. Results The rate of ametropia was 36.08%, varied significantly with different groups. The prevalence among female students was higher than that among males. The visual acuity reduced obviously with the grade being higher. With the grade being higher, the prevalence of hypermetropia decreased while the prevalence of myopia increased. Conclusion Myopia is the main cause of ametropia in primary students. Early management of myopia may play an important role in controlling students＇ ametropia.
