This study aimed to provide a comprehensive assessment of burden estimates and the secular trend of blindness and vision loss, as measured by years lived with disability (YLDs), at the global, regional, and national levels.
The age-standardized YLD rates (ASYRs) due to blindness and vision loss and its subtypes, including moderate vision loss, severe vision loss, blindness, and presbyopia, from 1990 to 2019 were extracted from the Global Burden of Disease Study 2019 database. The estimated annual percentage changes (EAPCs) were calculated to quantify the temporal trends in the ASYRs due to blindness and vision loss.
In 2019, the global ASYRs per 100,000 population was 327.98 for blindness and vision loss, specifically, 85.81 for moderate vision loss, 74.86 for severe vision loss, 95.03 for blindness, and 62.27 for presbyopia. From 1990 to 2019, the ASYRs due to blindness and vision loss slightly decreased. Females showed higher ASYRs than males in 2019. The global highest ASYRs were observed in South Asia and sub-Saharan Africa. Negative associations were found between the burden estimates of blindness and vision loss and the sociodemographic index levels. The EAPCs of ASYRs in blindness and vision loss were significantly negatively correlated with the ASYRs in 1990 and positively correlated with human development indices in 2019.
Globally, blindness and vision loss continue to cause great losses of healthy life. Reasonable resource allocation and health-service planning are needed for the prevention and early intervention of disabilities caused by vision loss.
本研究旨在全面评估全球、地区和国家层面因失明和视力丧失导致的残疾年数（YLDs）的负担估计和时间趋势。
从全球疾病负担研究 2019 年数据库中提取了 1990 年至 2019 年因失明和视力丧失及其亚型（包括中度视力丧失、重度视力丧失、失明和老视）导致的年龄标准化 YLD 率（ASYRs）。计算了估计的年平均变化率（EAPCs），以量化失明和视力丧失的 ASYRs 的时间趋势。
2019 年，全球每 10 万人失明和视力丧失的 ASYRs 为 327.98，具体为中度视力丧失 85.81，重度视力丧失 74.86，失明 95.03，老视 62.27。从 1990 年到 2019 年，失明和视力丧失的 ASYRs 略有下降。2019 年女性的 ASYRs 高于男性。全球失明和视力丧失的 ASYRs 最高的地区是南亚和撒哈拉以南非洲。失明和视力丧失的负担估计与社会人口指数水平呈负相关。失明和视力丧失的 ASYRs 的 EAPCs 与 1990 年的 ASYRs 呈显著负相关，与 2019 年的人类发展指数呈正相关。
在全球范围内，失明和视力丧失继续导致大量健康生命损失。需要合理分配资源和规划卫生服务，以预防和早期干预视力丧失导致的残疾。
