New data reveals that following decades of declining avoidable blindness, these statistics are expected to increase “dramatically” between 2015 and 2050.
Published in The Lancet Global Health, the paper from the Vision Loss Expert Group (VLEG) identifies the leading causes of blindness and moderate and severe vision impairment (MSVI) in 2015.
Co-authored by Anglia Ruskin University’s Professor Rupert Bourne and Imperial College London’s Dr Seth Flaxman, the study reports that of the 253 million people worldwide who are currently blind or have MSVI, 123.8 million because of uncorrected refractive error, and 65.2 million due to cataract.
Focusing on Europe, the paper reports that in Western Europe in 2015, uncorrected refractive errors accounted for 49% of MSVI cases and 15% of blindness. Furthermore, cataract accounted for 15.5% and 21% respectively.
Analysing data from 1990 to 2015, VLEG shows that during this period, 90 million people globally were treated or prevented from becoming blind or visually impaired.
