Naidoo K, Kempen JH, Gichuhi S, et al. - Researchers conducted this systematic review and meta-analysis to evaluate the prevalence and causes of vision loss in sub-Saharan Africa (SSA) in 2015, compared with prior years, and to estimate expected values for 2020. They evaluated the blindness prevalence (presenting distance visual acuity < 3/60 in the better eye), moderate and severe vision impairment (MSVI; presenting distance visual acuity < 6/18 but ≥ 3/60) and mild vision impairment (MVI; presenting distance visual acuity < 6/12 and ≥ 6/18), and also near vision impairment (< N6 or N8 in the presence of ≥ 6/12 best-corrected distance visual acuity) in SSA for 1990, 2010, 2015 and 2020. Cataract and undercorrected refractive error, two of the main causes of blindness and vision impairment, are treatment-reversible and therefore promising targets to alleviate vision impairment in SSA.
