This study explores the relationship between the recalled age of first distance prescription and the final myopic refractive error developed in adults.
Adult office workers, sent for a general health check-up without refractive selection, completed a questionnaire about age of first distance prescription, years of university study, and parental history of myopia, and were subjectively refracted by an ophthalmologist.
Average age of the 397 consecutive myopic subjects was 42.6 +/- 9.6 years and 80.6% were males. The median age of first prescription was 20 years. In the group with earlier first distance prescription (ages 3 to 10), 25.6% developed low final refractive errors (-0.50 to -3.0 diopters), 38.5% developed moderate myopia (< -3.0 to -6.0 diopters), and 35.9% developed high myopia (< -6.0 diopters), while in the groups with later first distance prescription (ages 23 to 30), 90-100% developed low final refractive errors.
Subjects developing myopia after age 20 had low myopia. Those subjects with an early recalled age of first prescription had a broad spectrum of myopic refractive errors, including a high proportion (approximately 2/3) of moderate to high myopia, and approximately 1/3 of low myopia.
本研究探讨首次远距离配镜时回忆起的年龄与成人最终发生的近视屈光不正之间的关系。
成年上班族在未进行屈光筛选的情况下接受一般健康检查，完成一份关于首次远距离配镜年龄、大学学习年限和近视家族史的问卷，并由眼科医生进行主观验光。
397例连续近视患者的平均年龄为42.6±9.6岁，男性占80.6%。首次配镜的中位年龄为20岁。在首次远距离配镜年龄较早的组（3至10岁）中，25.6%最终发展为低度屈光不正（-0.50至-3.0屈光度），38.5%发展为中度近视（<-3.0至-6.0屈光度），35.9%发展为高度近视（<-6.0屈光度），而在首次远距离配镜年龄较晚的组（23至30岁）中，90%-100%最终发展为低度屈光不正。
20岁后发生近视的受试者为低度近视。那些首次配镜年龄回忆较早的受试者近视屈光不正范围较广，包括高比例（约2/3）的中度至高度近视和约1/3的低度近视。
