Abstract

Age-corrected normal values for the Opacity Lens Meter (OLM) 701 were established by measuring 1598 eyes of 799 healthy volunteers. This study revealed a remarkable age-relation for the normal values. The average readings of the OLM of the 30-year-old subjects were around 10 units whereas the average for the 65-year-olds was close to 20 units. The best fit of the opacity vs. age was a quadratic function. The interindividual variation was small in the young and quite large in the older population. The correlation between contralateral eyes was high (R = 0.93).

摘要

通过测量799名健康志愿者的1598只眼睛，建立了Opacity Lens Meter（OLM）701的年龄校正正常值。这项研究揭示了正常值与年龄之间的显著关系。30岁受试者的OLM平均读数约为10个单位，而65岁受试者的平均读数接近20个单位。不透明度与年龄的最佳拟合是二次函数。个体间差异在年轻人中较小，而在老年人群中较大。对侧眼之间的相关性很高（R = 0.93）。
