Global burden of low vision and blindness due to age-related macular degeneration from 1990 to 2021 and projections for 2050

This study indicates that between 1990 and 2021, the global prevalent cases and DALYs caused by AMD-related low vision and blindness have increased over the past three decades, correlating with factors such as age, gender, socioeconomic status, and geographical location. Predictive models indicate that as the population ages, the number of patients with low vision and blindness due to AMD, along with associated DALYs, will continue to rise. By 2050, it is expected that over 9 million people worldwide will be affected by AMD-related vision loss, with women being particularly impacted. These findings can provide data support for public health planning, resource allocation, and the formulation of medical policies, ensuring an effective response to the challenges posed by the future increase in AMD-related low vision and blindness.
