Global burden of blindness or visually impairment attributable to diabetic retinopathy in the adults aged 70 years and older, 1990–2021: Results from the global burden of disease study in 2021
Authors' conclusion
DR-related vision loss among older adults is rising globally, with clear regional and gender disparities. Targeted strategies are essential to mitigate this burden in aging populations.
Study context
- Population
- Adults aged 70 and older with diabetic retinopathy (DR)-related vision loss, global, 1990–2021
- Primary endpoint
- Prevalence and years lived with disability (YLDs) of DR-related vision loss, and trends
- Follow-up
- 1990–2021
Methodological detailsstratified by region, country, gender and age, estimated annual percentage changes (EAPCs)

401,260 cases
Further findings
Regional, age and socio-demographic index (SDI) distribution
- Burden highest in East Asia, Western Europe and South Asia
- DR burden increased with age and SDI
