What is the leading cause of vision loss in people over 50 years of age?

Age-related macular degeneration (AMD) is the leading cause of vision loss in individuals over the age of 50. This condition affects the central part of the retina, known as the macula, which is responsible for sharp, central vision essential for activities such as reading and recognizing faces. As AMD progresses, it can lead to significant vision impairment, making it challenging for affected individuals to perform daily activities.

While cataracts, diabetic retinopathy, and glaucoma are also significant causes of vision loss, they are not as prevalent as AMD in this age group. Cataracts can cause blurred vision due to clouding of the lens but can often be treated effectively with surgery. Diabetic retinopathy is primarily associated with individuals who have diabetes and occurs due to damage to the blood vessels in the retina. Glaucoma can lead to peripheral vision loss and potentially blindness but is less common as a leading cause of central vision loss compared to AMD among older adults. Understanding the prevalence and impact of AMD helps in early detection and appropriate management to preserve vision in aging populations.
