A study published May 19 by researchers at the USC Gayle and Edward Roski Eye Institute in\u00a0JAMA Ophthalmology<\/em>\u00a0found 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.
\nThe 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.
\nThe groups most at risk \u2014 non-Hispanic whites, older Americans and women \u2014 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.
\n\u201cThis study gives us a GPS for our nation\u2019s future eye health,\u201d Varma said. \u201cIncreased education and vision screenings are critical for both younger and older Americans, but especially women and minorities over age 40, to prevent vision impairment that can dramatically worsen their quality of life. The earlier we can diagnose these blinding eye diseases through an annual eye exam and obtain eye care, the more people will have the chance to live longer lives without the physical limitations and emotional challenges of vision loss and blindness.\u201d
\nEyesight loss has both a human and societal toll. Other studies have identified that people who are visually impaired or blind can suffer both physical and mental health decline including an increased risk for chronic health conditions such as diabetes, unintended injuries including a higher risk for falls, social isolation and withdrawal from activities that require driving or independent mobility, depression and even death.
\nAccording to Prevent Blindness America the economic burden from vision loss and eye disorders cost the U.S. $139 billion in 2013. When compared to the Centers for Disease Control (CDC) 2010 data on the annual economic impact of chronic conditions such as heart disease\/stroke ($315 billion), diabetes ($245 billion) and cancer ($157 billion) \u2014 vision impairment and loss is among the costliest health conditions in the nation.
\nBased on U.S. Census Bureau data, Millennials (born 1982-2004) have recently surpassed the Baby Boom generation (born 1946-1964) as the largest age cohort in the U.S., but it is the aging boomers who are driving the increase in vision impairment and blindness over the next 35 years. By 2050, 86.7 million boomers will be over the age of 65 \u2014 almost 1 in 5 Americans \u2014 when many debilitating eye diseases and vision loss can occur.
\nThe researchers examined six major U.S. population-based studies on VI and blindness and pooled the data from adults age 40 and above. Demographic and geographic variations including reporting by age, gender, race\/ethnicity and per capita prevalence by state using U.S. Census projections were analyzed to calculate the study findings.
\nAs one of the world\u2019s leading experts in population-based eye diseases, Varma has led several NEI-funded studies including the recent largest population-based study of adult Latinos and age-related macular degeneration (AMD) Los Angeles Latino Eye Study (LALES) and the largest study of Chinese Americans and AMD Chinese American Eye Study (CHES). He has also been the principal investigator of many major National Institutes of Health (NIH)-funded studies including the Multi-Ethnic Pediatric Eye Diseases Study (MEPEDS) and the African-American Eye Disease Study (AFEDS). The USC Roski Eye Institute is ranked in the Top 2 of the nation\u2019s top grant recipients from the NEI and has achieved more than $32 million in annual grant funding.
\nThis research was supported by NEI-funded grants: U10 EY011753, U10 EY017337 and an unrestricted departmental grant from Research to Prevent Blindness, New York, NY 10017.<\/p>\n\n\n\n<\/div>\n
