目的：本研究是流行病学研究 Inter99 眼科研究的一部分。该研究的目的是描述丹麦郊区人群的屈光不正和视力 (VA)。 方法：Inter99 眼科研究由 970 名年龄 30-60 岁的受试者组成，其中包括随机对照组以及缺血性心脏病和糖尿病高危人群。本研究提供了对照组 (n = 502) 的视力和屈光数据。所有受试者均完成了详细的调查问卷，并接受了标准化的一般身体和眼科检查，包括确定最佳矫正视力和主观验光。 结果：1 名受试者的一只眼睛的视力小于或等于 0.05，11 名受试者的 11 只眼睛的视力小于或等于 0.3。视功能下降的主要原因是斜视性弱视。总人口中 33.1% 的右眼存在近视（小于或等于 - 0.5 D，球面等效屈光度），但拥有大学学位的受试者中有 56.8% 存在近视。结论：斜视性弱视是单眼视力障碍的重要原因。具有大学学位的受试者的近视发生率大约是其余研究人群的两倍。
Purpose: The present study was performed as part of an epidemiological study, the Inter99 Eye Study. The aim of the study was to describe refractive errors and visual acuity (VA) in a suburban Danish population.Methods: The Inter99 Eye Study comprised 970 subjects aged 30-60 years and included a random control group as well as groups at high risk for ischaemic heart disease and diabetes mellitus. The present study presents VAs and refractive data from the control group (n = 502). All subjects completed a detailed questionnaire and underwent a standardized general physical and ophthalmic examination including determination of best corrected VA and subjective refractioning.Results: Visual acuity less than or equal to 0.05 was found in one eye of one subject and VA less than or equal to 0.3 in 11 eyes of 11 subjects. The main cause of reduced visual function was strabismic amblyopia. Myopia (less than or equal to - 0.5 D, spherical equivalent refraction) was present in 33.1% of right eyes of the total population but in 56.8% of subjects with a university degree.Conclusions: Strabismic amblyopia was a significant cause of unilateral visual impairment. Myopia was approximately twice as frequent in subjects with a university degree as in the remaining study population.
