Geographic Disparity of Severe Vision Loss in the United States, 2009–2013
An analysis of U.S. county-level data found a significant correlation between severe vision loss and poverty. Southern states had the highest prevalence of severe vision loss and poverty. Severe vision loss (SVL) often affects activities of daily living, leads to depression and social isolation, and increases the risk of falls and injuries. Limited data and research are available at the local levels, where interventions and policy decisions to reduce the burden of vision loss and eliminate disparities are often developed and implemented. After examining county-level data from the American Community Survey, SVL prevalence was strongly correlated with poverty. The majority of counties in the top 25 percent for both SVL and poverty were primarily in the southern United States.
