A population-based survey of 760 people 65-74 years of age was conducted in the municipality of Tierp, central Sweden. The methods used to identify glaucoma suspects were applanation tonometry, automatic perimetry (Competer 350), and binocular assessment of the optic disc. For a diagnosis of definite open-angle glaucoma, a visual field defect was required. Open-angle glaucoma was found at a prevalence of 5.70% (95% confidence interval: 4.12-7.27), which is higher than those figures reported for comparable surveys carried out on white populations. The occurrence of capsular glaucoma may in part explain this finding. Twenty of the 45 open-angle glaucomas were diagnosed before the survey. In this category, capsular glaucoma accounted for 60%, whereas 84% of cases detected during the survey were chronic simple glaucomas. Eight cases (18%) were classified as normal tension glaucoma, all of whom were diagnosed during the survey. Chronic simple glaucoma was significantly more prevalent in males than in females.
在瑞典中部蒂尔普市对760名65至74岁的人群进行了一项基于人群的调查。用于识别青光眼疑似患者的方法包括压平眼压测量法、自动视野计检查（Competer 350）以及视盘的双眼评估。对于确诊开角型青光眼，需要存在视野缺损。发现开角型青光眼的患病率为5.70%（95%置信区间：4.12 - 7.27），这高于对白人人群进行的类似调查所报告的数字。囊膜性青光眼的发生可能部分解释了这一发现。45例开角型青光眼中有20例在调查前被诊断出来。在这一类中，囊膜性青光眼占60%，而在调查期间检测出的病例中84%为慢性单纯性青光眼。8例（18%）被归类为正常眼压性青光眼，所有这些病例都是在调查期间被诊断出来的。慢性单纯性青光眼在男性中的患病率显著高于女性。
