1 gru 2020 · We fitted hierarchical models to estimate prevalence (with 95% uncertainty intervals [UIs]) of moderate and severe vision impairment (MSVI; presenting visual acuity from <6/18 to 3/60) and blindness (<3/60 or less than 10° visual field around central fixation) by cause, age, region, and year.

Globally, 1.1 billion people were living with vision loss in 2020. - 43 million people are blind (crude prevalence 0.5%) - 295 million people have moderate to severe visual impairment (crude prevalence 3.7%) - 258 million people have mild visual impairment (crude prevalence 3.3%)

1 gru 2020 · The Vision Loss Expert Group (VLEG) previously published global, regional, and country-level estimates of mild or more severe distance vision impairment from 1990 to 2015. They found an overall decrease in age-standardised prevalence of distance vision but an increase in total people with vision loss.
We forecast estimates of vision loss up to 2050. Findings: In 2020, an estimated 43·3 million (95% UI 37·6-48·4) people were blind, of whom 23·9 million (55%; 20·8-26·8) were estimated to be female.
There are 77 million (10%) people with vision loss that require ongoing management and treatment, for conditions such as age-related macular degeneration, glaucoma and diabetic retinopathy. There are also 295 million people with mild vision loss for which cause data is not available.
The definitions of vision loss used by the VLEG in 2020 are based on the International Classification of Diseases 11 (2018) classification. What is the difference between crude and age-standardised prevalence? Crude prevalence: The actual percentage of vision loss in each country or region.
