What is the most common cause of vision loss in older adults?

• A. Cataracts
• B. Macular degeneration
• C. Glaucoma
• D. Diabetic retinopathy

Answer: (B)

The most common cause of vision loss in older adults is macular degeneration. This condition, particularly age-related macular degeneration (AMD), affects the central part of the retina called the macula, which is responsible for sharp, detailed vision. As AMD progresses, it can lead to a gradual loss of central vision, making it difficult for individuals to perform tasks like reading, driving, or recognizing faces, all of which are critical as one ages.

While cataracts, glaucoma, and diabetic retinopathy are also significant causes of vision impairment in older adults, macular degeneration is more prevalent and has a more profound impact on overall visual function for this population. The increasing incidence of AMD is largely attributed to aging and is compounded by lifestyle factors and genetics. This understanding underscores the importance of regular eye examinations for early detection and management of visual changes as individuals grow older.
