To determine the prevalence of visual impairment (VI) in populations 65 year or older from six European countries and describe the association with vision-related quality of life. VI was defined according to WHO as best corrected visual acuity <6/18/log MAR >0,48 (World Health Organization (1992): International Statistical Classification of Diseases and Related Health Problems, 10th revised ed. Vol 1. Geneva).
4166 participants in The European Eye study, 65 years and older selected randomly from the general census in the participating centres, were interviewed for vision-related quality of life and underwent an eye exam including distance visual acuity, refraction and fundus photography.
The prevalence of VI rose with increasing age and more so in women. There was a pattern of a higher prevalence of VI in the Mediterranean countries compared to Northern European countries with the exception of Tallinn (Estonia) which had higher VI prevalence rates than the other north European centres. The prevalence of low vision was 3% or less in all centres. Blindness prevalence varied from 2% to less than half a per cent. Vision-related quality of life was strongly associated with visual acuity and the presence of bilateral age-related macular degeneration.
The prevalence of visual impairment in the examined ageing European populations shows a definite increasing trend from north to south.
确定六个欧洲国家 65 岁及以上人群中视力障碍(VI)的患病率,并描述其与视力相关生活质量的关系。VI 按照世界卫生组织(WHO)的定义为最佳矫正视力<6/18/logMAR >0.48(世界卫生组织(1992 年):国际疾病和相关健康问题统计分类第 10 次修订版。第 1 卷。日内瓦)。
从参与中心的一般人口普查中随机选择的 4166 名参加欧洲眼研究的 65 岁及以上的参与者接受了与视力相关的生活质量调查,并接受了眼部检查,包括远视力、屈光度和眼底照相。
VI 的患病率随着年龄的增长而增加,女性更为明显。与北欧国家相比,地中海国家 VI 的患病率更高,但塔林(爱沙尼亚)除外,其 VI 患病率高于其他北欧中心。所有中心的低视力患病率均为 3%或更低。失明患病率从 2%到不到一半不等。视力相关的生活质量与视力和双侧年龄相关性黄斑变性密切相关。
在检查的欧洲老龄化人群中,视力障碍的患病率从北到南呈明显上升趋势。
