Study: Visual impairment and blindness prevalence in the U.S. to double by 2050

June 2nd, 2016|

A study published May 19 by researchers at the USC Gayle and Edward Roski Eye Institute in JAMA Ophthalmology found that the U.S. prevalence in visual impairment (VI) and blindness is expected to double over the next 35 years. By 2050, the number of Americans with a variety of eye disease and impairment issues, including age-related macular degeneration (AMD), glaucoma, diabetic retinopathy (DR) and cataracts, will dramatically increase impacting both individuals and society. The National Eye Institute (NEI)-funded study, led by principal investigator, Rohit Varma, MD, MPH, interim dean of the Keck School of Medicine of USC and director of the USC Roski Eye Institute, found that by 2050, 16.4 million Americans over age 40 will have VI due to uncorrected refractive error compared to 8.2 million in 2015. In addition, more than 2 million age 40+ will be blind and 6.95 million will have VI by 2050 compared to 1.02 million and 3.22 million respectively from 2015. The groups most at risk — non-Hispanic whites, older Americans and women — do not change from 2015 data to 2050 projections. However, while African Americans have the highest prevalence of blindness and VI today (15.2 percent today growing to 16.3 percent by 2050), the Hispanic population will become the most at risk minority group for both VI and blindness increasing from 9.9 percent today to 20.3 percent in 2050. The study also examined data state by state and found Mississippi and Louisiana will have the highest per capita prevalence for blindness while Florida and Hawaii will lead the nation for VI per capita. “This study gives us a GPS for our nation’s future eye health,” Varma said. “Increased education and vision screenings are critical for both […]
