目的根据最新数据，估计了2010年全球和世卫组织区域视力损害的程度及其原因。视力损害的定义采用国际疾病分类第10版中的现行视力定义。方法对2000年至今已发表和未发表的调查结果进行系统回顾。对于没有视力障碍的数据的国家，估计是基于新开发的插补方法，考虑到国家的经济地位作为proxy.Results调查从39个国家满足本研究的纳入标准。在全球范围内，所有年龄段的视力受损人数估计为2.85亿，其中3900万人失明，不确定性为10- 20%。50岁及以上的人分别占视力受损者和盲人的65%和82%。结论2010年世界卫生组织（WHO）各地区视力损害是一个主要的健康问题，可预防的原因占全球总负担的80%。
Aim From the most recent data the magnitude of visual impairment and its causes in 2010 have been estimated, globally and by WHO region. The definitions of visual impairment are the current definitions of presenting vision in the International Classification of Diseases version 10.Methods A systematic review was conducted of published and unpublished surveys from 2000 to the present. For countries without data on visual impairment, estimates were based on newly developed imputation methods that took into account country economic status as proxy.Results Surveys from 39 countries satisfied the inclusion criteria for this study. Globally, the number of people of all ages visually impaired is estimated to be 285 million, of whom 39 million are blind, with uncertainties of 10-20%. People 50 years and older represent 65% and 82% of visually impaired and blind, respectively. The major causes of visual impairment are uncorrected refractive errors (43%) followed by cataract (33%); the first cause of blindness is cataract (51%).Conclusion This study indicates that visual impairment in 2010 is a major health issue that is unequally distributed among the WHO regions; the preventable causes are as high as 80% of the total global burden.
