Which statement about the macula is true in AMD?

• A. The macula is responsible for peripheral vision.
• B. The macula is destroyed leading to central vision loss.
• C. The macula controls eyelid movement.
• D. The macula thickens and clears vision.

Answer: (B)

Central vision loss occurs when the macula, the part of the retina responsible for sharp, detailed vision, degenerates in AMD. When the macula is damaged, tasks that require fine detail—reading, recognizing faces, and judging fine contrast—become difficult or impossible, while peripheral vision often remains intact. This is why the statement about the macula leading to central vision loss in AMD is true. The macula sits at the center of the retina and houses the fovea, the region with the highest visual acuity, so its deterioration directly impacts central vision. AMD can start as dry, with gradual macular thinning and drusen buildup, or as wet, with abnormal blood vessel growth under the macula causing scarring and rapid central vision loss. The other options don’t fit because peripheral vision is governed by areas outside the macula, eyelid movement is controlled by motor nerves rather than the macula, and the macula does not thicken to clear vision in AMD.
