Abstract:

Objective To assess the vision impairment burden in China in 2015 and to analyze the trend of it from 1990 to 2015. Design A systematic analysis. Participants Chinese population data from the Global Burden of Diseases Study 2016(GBD 2016). Methods Analyzing methods and data from GBD2016 were used. GBD study is a worldwide collaboration aimed at quantifying various health metrics of loss to diseases and injuries using standardized analysis program. These metrics enable comparison of health data across time and place, and across different diseases and injuries. Main Outcome Measures Years lived with disability (YLD), including YLD, YLD rate, proportion of YLD due to vision impairment. Results In 2015, the YLD for vision impairment burden in China was 4885 thousand, accounting for 17.3% of the total global visual imapairment YLD. YLD induced by visual impairment showed a trend of gradual increase with age. From 1990 to 2015, YLD for vision impairment increased year by year in China. In 2015, YLD (4885 thousand) increased by 69.4% compared with 1990 (2883 thousand). The age standardized YLD rate for vision impairment increased year by year from 1990 to 2010, but decreased from 2010 to 2015. The age-standardized YLD rate for vision impairment in China in 2015 (340.1/per 100 000) increased by 2.94% compared with 1990 (330.4/per 100 000). Conclusion From 1990 to 2015, the visual impairment burden in China was increasing year by year. After adjusting for age and population size, the burden of visual impairment decreased slightly after 2010. (Ophthalmol CHN, 2018, 27: 264-268)
