Notably, the vision loss burden caused by VAD showed a declining trend since 2014. The vision loss burden was more concentrated in the post-neonatal age group and decreased with increasing age. The age-standardised YLD rates were inversely correlated with HDI (\n                      <jats:italic>r<\/jats:italic>\n                      = \u20130\u00b72417,\n                      <jats:italic>P<\/jats:italic>\n                      = 0\u00b70084). The CI and Gini coefficients indicated that socio-economic-related and between-country inequality declined from 2000 to 2017. VAD was the eighth leading cause of the age-standardised prevalence rate and ninth leading cause of age-standardised YLD rate among fifteen causes of vision loss in 2017.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"S1368980021001324_as6\">\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>VAD has become one of the significant leading causes of vision loss globally.
