Preliminary GBD Expert Group Estimates of Global Number of Persons in 2010 with Blind and Visual Impairment: 33. 5 million Blind (29. 6 -38. 1) 199 million MSVI (177 -231)

Trends • The prevalence of blindness and MSVI has decreased in the last 20 years, despite the relative increase in older adults in the world population • However, due to population growth, the estimates suggest that absolute blind population has been stable and the population with MSVI has increased.

Summary Statistics • Prelim. estimates 33. 5 million people Blind in 2010 (29. 6, 38. 1), 60. 6% of Blind were female • 199 million (177, 231) had Moderate and Severe Visual Impairment in 2010, 56. 8% female • The highest age-standardized prevalence of blindness in those ≥ 50 years was in Western Sub. Saharan Africa at 5. 8% • The highest age-standardized prevalence of MSVI in those ≥ 50 years was in South Asia at 24. 1%

Summary Trends • The global age-standardized prevalence of blindness for adults aged 50+ years decreased from 3. 1% (2. 7%-3. 6%) worldwide in 1990 to 2. 0% (1. 8%-2. 3%) in 2010. • The global age-standardized prevalence of MSVI for adults aged 50+ years decreased from 14. 2% (11. 2%-16. 1%) worldwide in 1990 to 10. 8% (9. 7%-12. 4%) in 2010.
