Abstract

To estimate the prevalence of vision loss for 2020 in South and Central Asia and analyze trends since 1990. In a systematic literature review, we estimated the prevalence of blindness, visual impairment (VI) and presbyopia-related VI in 1990,2000,2010, and 2020. The study included 103 population-based studies. In South/Central Asia combined, age-standardized prevalence of blindness, moderate-to-severe VI (MSVI), moderate VI, severe VI, mild VI and presbyopia-related VI for all ages was 0.65% (95% uncertainty interval (UI):0.56/0.74), 5.06 (4.55/5.59), 4.40 (3.91/4.94), 0.65 (0.57/0.74), 3.21 (2.89/3.56), and 8.77 (6.37/11.48), respectively, with higher values for women than men. From 2000 to 2020, changes in age-standardized prevalence in South Asia were −36.85 (−36.94/−36.76), −7.01 (−7.13/−6.90), −5.86 (−5.99/−5.73), −13.96 (−14.09/−13.82), −9.55 (−9.66/−9.44), and −8.62 (−8.93/−8.31), respectively for men, and −38.50 (−38.59/−38.40), −10.12 (−10.22/−10.01), −9.23(−9.36/−9.10), −14.86 (−14.99/−14.73), −9.44 (−9.56/−9.33), and −7.78 (−8.09/−7.48), respectively for women. From 2000/2020, the changes in age-standardized prevalence figures in Central Asia were −21.44 (−21.58/−21.30), −2.75 (−2.87/−2.64), −2.17 (−2.30/−2.04), −7.12 (−7.26/−6.99), −5.36 (−5.48/−5.25), and −3.67(−4.02/−3.32), respectively for men, and −21.13 (−21.27/−20.99), −2.70 (−2.81/−2.58), −2.18 (−2.30/−2.05), −6.93 (−7.07/−6.80), −5.03 (−5.14/−4.91), and −2.65 (−3.00/−2.30), respectively, for women. In 2020, 11.94 million (9.98-14.07) and 0.30 million (0.24-0.36) individuals were blind, and 96.22 million (84.12-110.27) and 2.95 million (2.52-3.43) had MSVI in South Asia and Central Asia, respectively. Despite a higher decrease between 2000 and 2020, the age-standardized prevalence of blindness and MSVI were higher in South Asia than in Central Asia in 2020. The number of people affected increased due to population growth and improved longevity.
