This study provides global estimates of the leading causes of vision impairment and blindness for 2015, examines trends since 1990, and provides projections to 2020.
This study updates the estimates of the global and regional prevalence of causes of blindness and vision impairment.
The new analysis of the Global Vision Database by the Vision Loss Expert Group incorporates 61 new studies from 35 different countries and where available includes more precise disaggregated data supplied by study investigators than are available in their published outputs.
This database contains data for both presenting and best-corrected visual acuity and causes of vision impairment from 3 983 541 participants examined in 288 population-based studies from a systematic review of the published literature and analysis of unpublished literature. Furthermore, it uses an improved statistical analysis and provides projections of blindness and vision impairment, by cause, to 2020.
