对太原市中小学生边缘视力268眼进行了屈光度测定,结果:边缘视力眼小瞳检影有34％为“近视”,散瞳检影有16.8％为“近视”;“假性近视”占17.2％。对其中126眼进行了6个月的追踪观察,结果:41人发生近视,占32.4％。上述结果表明:边缘视力学生的屈光状态易变性较大,近视倾向较强,应常规进行屈光检查,以屈光度低于-0.25D的做为重点防治对象。 Refractive degree was measured in 268 eyes of primary and secondary school students in Taiyuan City. Results: 34% of the pupils in the marginal vision pupil were “myopia”, 16.8% of the mydriasis were “myopia”; “false myopia” accounted for 17.2% %. A total of 126 eyes were followed up for 6 months. Results: 41 people had myopia, accounting for 32.4%. The above results show that: the edge of the visual acuity of larger variability of students, myopia tends to be relatively strong, refractive examination should be routine to diopter below -0.25D as a key prevention and control targets.
