目的：视力障碍是世界范围内主要的可预防的致残原因。然而，目前还没有关于视力障碍患病率的全球和区域趋势的研究。我们估计了过去20年世界范围内视力损害的患病率及其变化。设计：系统回顾。参与者：对1980年至2012年期间视力障碍和失明的已发表和未发表的基于人群的数据进行系统回顾。方法：拟合分层模型，拟合估计中、重度视力障碍（MSVI，定义为呈现视力= 3/60）的患病率和失明（呈现视力= 50岁）的患病率在撒哈拉以南非洲西部（6.0%,95% CI, 4.6%-7.1%）、撒哈拉以南非洲东部（5.7%,95% CI, 4.4%-6.9%）、南亚（4.4%,95% CI, 3.5%-5.1%）、北非和中东(4.6%；95% CI, 3.5%-5.8%)，而高收入地区的失明患病率为
Purpose: Vision impairment is a leading and largely preventable cause of disability worldwide. However, no study of global and regional trends in the prevalence of vision impairment has been carried out. We estimated the prevalence of vision impairment and its changes worldwide for the past 20 years.Design: Systematic review.Participants: A systematic review of published and unpublished population-based data on vision impairment and blindness from 1980 through 2012.Methods: Hierarchical models were fitted fitted to estimate the prevalence of moderate and severe vision impairment (MSVI; defined as presenting visual acuity = 3/60) and the prevalence of blindness (presenting visual acuity = 50 years) was more than 4% in Western Sub-Saharan Africa (6.0%; 95% CI, 4.6%-7.1%), Eastern Sub-Saharan Africa (5.7%; 95% CI, 4.4%-6.9%), South Asia (4.4%; 95% CI, 3.5%-5.1%), and North Africa and the Middle East (4.6%; 95% CI, 3.5%-5.8%), in contrast to high-income regions with blindness prevalences of
