What is the leading cause of blindness in older adults?

• A. Cataracts
• B. Diabetic retinopathy
• C. Glaucoma
• D. Age-related macular degeneration

Answer: (D)

Age-related macular degeneration (AMD) is recognized as the leading cause of blindness in older adults due to its impact on central vision. This condition primarily affects the macula, which is crucial for sharp, detailed central vision necessary for activities like reading and driving. AMD can result in significant vision loss as it progresses, leading to challenges in daily activities and a diminished quality of life. While cataracts, diabetic retinopathy, and glaucoma also contribute substantially to visual impairment in the aging population, they do not match the prevalence and specific central vision loss associated with AMD. Cataracts are common and treatable, often resolved with surgery. Diabetic retinopathy primarily affects those with diabetes and can be mitigated with good blood sugar control. Glaucoma involves peripheral vision loss and can often be managed with treatment, but it does not predominantly cause blindness in the same manner as AMD. Thus, the specific nature of AMD's effects on vision solidifies its status as the foremost cause of blindness in the older demographic.
