Macular degeneration primarily causes which change in vision?

• A. A central blind spot in the vision with peripheral vision retained
• B. A peripheral blind spot with central vision preserved
• C. Total loss of vision
• D. No vision changes

Answer: (A)

Macular degeneration targets the macula, the central area of the retina responsible for sharp, detailed vision. When the macula deteriorates, central vision becomes impaired, creating a central blind spot in the visual field while peripheral vision remains intact. This preserved side vision is why people with macular degeneration can still see objects to the sides but have trouble with tasks that require clear central sight, like reading or recognizing faces. The other options don’t fit because macular degeneration does not primarily cause peripheral vision loss, total blindness, or no vision changes.
