TY - JOUR PY - 2023// TI - Persistence of severe global inequalities in the burden of blindness and vision loss from 1990 to 2019: findings from the Global Burden of Disease Study 2019 JO - British journal of ophthalmology A1 - Li, Yuancun A1 - Wang, Hongxi A1 - Guan, Zhiqiang A1 - Guo, Chengyao A1 - Guo, Pi A1 - Du, Yali A1 - Yin, Shengjie A1 - Chen, Binyao A1 - Jiang, Jiao A1 - Ma, Yueting A1 - Jing, Liu A1 - Huang, Yingzi A1 - Zheng, Ke A1 - Ma, Qian A1 - Zhou, Ruiqing A1 - Chen, Min A1 - Congdon, Nathan A1 - Qiu, Kunliang A1 - Zhang, Mingzhi SP - ePub EP - ePub VL - ePub IS - ePub N2 - AIMS: To assess the global burden and economic inequalities in the distribution of blindness and vision loss between 1990 and 2019.

METHODS: A secondary analysis of the Global Burden of Diseases, Injuries and Risk Factors Study (GBD) 2019. Data for disability-adjusted life-years (DALYs) due to blindness and vision loss were extracted from the GBD 2019. Data for gross domestic product per capita were extracted from the World Bank database. Slope index of inequality (SII) and concentration index were computed to assess absolute and relative cross-national health inequality, respectively.

RESULTS: Countries with high, high-middle, middle, low-middle and low Socio-demographic Index (SDI) had decline of age-standardised DALY rate of 4.3%, 5.2%, 16.0%, 21.4% and 11.30% from 1990 to 2019, respectively. The poorest 50% of world citizens bore 59.0% and 66.2% of the burden of blindness and vision loss in 1990 and 2019, respectively. The absolute cross-national inequality (SII) fell from -303.5 (95% CI -370.8 to -236.2) in 1990 to -256.0 (95% CI -288.1 to -223.8) in 2019. The relative inequality (concentration index) for global blindness and vision loss remained essentially constant between 1991 (-0.197, 95% CI -0.234 to -0.160) and 2019 (-0.193, 95% CI -0.216 to -0.169).

CONCLUSION: Though countries with middle and low-middle SDI were the most successful in decreasing burden of blindness and vision loss, a high level of cross-national health inequality persisted over the past three decades. More attention must be paid to the elimination of avoidable blindness and vision loss in low-income and middle-income countries.
