摘要
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。
The ocular refraction was measured in 268 eyes of the school children with visual acuity 5.0, aged 7～15 in Taiyuan. The results showed that 45 eyes were myopic in refractive state (16.8%), 46 eyes were pseudomyopic in refractive state (17.2%)in 268 eyes with visual acuity 5.0. The results of following observation of 126 eyes for six months indicated that 41 eyes became myopic(depraved vision)(32.5％), of which 26 eyes were previously myopic under refraction, 13 eyes emmetropic and 2 eyes farsighted. The conclusion is that the eyes with visuanl acuity 5.0 have a greater possibility of becoming myopic, Routine ocular refraction should be conducted in the school children. Some measures should be taken in those who have the value under -0.25D to prevent the onset of myopia.
