Which is the leading cause of functional blindness in older adults?

The leading cause of functional blindness in older adults is age-related macular degeneration (AMD). This condition affects the macula, the part of the retina responsible for central vision, leading to a gradual loss of sharpness and detail in vision. Other significant causes include cataracts and diabetic retinopathy, but AMD is the most prevalent among the elderly population. Regular eye examinations and early detection can help manage and mitigate the impact of these conditions.
