Description
Summary:To determine the prevalence and causes of vision loss and calculate the effective cataract surgery coverage (eCSC) in adults aged 60 years and older in Latin America and the Caribbean in 2020. The International Agency for the Prevention of Blindness Vision Atlas and the Rapid Assessment of Avoidable Blindness databases were used as data source. The collected data were used to estimate the prevalence and causes of vision loss in people aged 60 years and older, and to determine the eCSC. The overall prevalence of moderate to severe vision impairment (MSVI) and blindness in Latin America and the Caribbean were 14.14% and 2.94%, respectively. Tropical Latin America was the subregion with the highest prevalence of blindness (3.89%) while Southern Latin America had the lowest (0.96%). For both MSVI and blindness, cataract was the main cause of vision loss. The eCSC rates showed great variation, ranging from 4.0% in Guatemala to 75.2% in Suriname. The prevalence of vision loss in adults aged 60 years and older in Latin America and the Caribbean was higher than previous estimates on younger groups. Cataract was the main cause of blindness, and the eCSC indicates that the outcomes from cataract surgery should be improved. Specific actions associated with improving access, integrating eye assessment with primary care programs, expanding the use of telemedicine, and improving data quality should be taken by public health authorities aiming to address vision loss in this group.
