Diabetic Retinopathy
A new study published today in JAMA Ophthalmology, “Prevalence of Diabetic Retinopathy in the US in 2021,” found that in 2021, an estimated 9.6 million people in the United States (26.4 percent of those with diabetes) had diabetic retinopathy (DR), and 1.84 million people (5.1 percent of those with diabetes) had vision-threatening diabetic retinopathy (VTDR). The number of people aged 40 years and older living with diabetes-related eye disease more than doubled since prevalence was last estimated in 2004. VTDR has also almost doubled since last estimated in 2004.
Additional key findings from the study include:
- Approximately 1 in 4 Americans ages 40 and older with diabetes have DR.
- These new estimates include the prevalence of DR and VTDR in people younger than age 40 years. Past prevalence estimates were only for the US population aged 40 and older.
- VTDR prevalence rates are higher for Black (8.7 percent) and Hispanic (7.1 percent) individuals than White individuals (3.6 percent). Thus, a higher percentage of Black and Hispanic individuals with diabetes are at risk for vision loss compared to their White counterparts.
- The prevalence of both DR and VTDR varied widely by U.S. state and county. After standardizing by age, sex/gender, and race/ethnicity, rates of DR among persons with diabetes ranged from a low of 21.2 percent in Nevada to a high of 34.2 percent in Hawaii.
- Prevalence of DR and VTDR among people with diabetes increased substantially with age but then decreased in the older age groups, likely because DR and VTDR are markers for more severe diabetes, which can lead to early mortality.
