摘要
为研究隐斜、近视屈光和近视弧随单眼视力低下变化的相关情况,我们对一眼视力正常,另眼视力低下的103名大学生随机抽样检查,其视力低于0.6者定为视力低下眼;取双眼视力相同而等于样本组视力低下眼者66人作为对照,按0.5—0.1和0.05的视力顺序,所有人被分做六个视力组进行配对比较,通过t一检验,发现单眼视力低下者的上隐斜患病率及其近视屈光度和近视弧宽度的双眼间的差值显著高于对照组(p<0.01),这些差值均随视力低下变化呈高度负相关(r=-0.906)。
One hundred and three collegians with one normal vision eye and the other lowered vision eye were randomly investigated for the observation of correlation between heterophorias, myopic refraction and crescent and its uniocular hypopsia. Eyes with under 0.6 on the visual chart were considered vision lowered eye (VLE). 66 subjects with approachable vision of both eyes, equivalent to VLE of the tested group, were served as control. In order of vision from 0.5 to 0.1 and 0.05, comparison was done among all subjects divided into six visual groups. By t-test, it was found that the prevalence of hyperphoria, the differential value between both eyes on myopic diopters and crescent extents in uniocular hypopsic Subjects were significantly higher (P<0.01) than those in the control group, These values show a highly negative correlation with the variation of visual lowering (r=-0.906).
