Which condition is the leading cause of blindness in the US?

The leading cause of blindness in the United States is diabetic retinopathy. This condition is a complication of diabetes, where high blood sugar levels damage the blood vessels in the retina over time, leading to vision impairment. Diabetic retinopathy can progress to more severe stages, ultimately resulting in significant vision loss or blindness if not properly managed.

This condition is particularly concerning because it can develop without any noticeable symptoms in its early stages, which means individuals with diabetes may not be aware of their risk. Regular eye examinations are crucial for early detection and treatment to prevent irreversible damage.

While other conditions listed, such as cataracts, glaucoma, and macular degeneration, also contribute to vision loss, studies indicate that diabetic retinopathy is the most significant contributor to blindness among working-age individuals in the U.S. This underscores the importance of diabetes management and regular eye care for those affected by the disease.
