In macular degeneration, which description best fits the vision pattern?

Explanation:
Macular degeneration damages the macula, the central part of the retina that provides sharp, detailed vision. When the macula is affected, central vision becomes blurry or a small central area in sight is lost, while the rest of the visual field around the edges remains intact. That means you can see things to the sides normally, but fine detail in the center—like recognizing faces, reading, or recognizing small print—is impaired. This creates a central blind spot or distorted central vision, not a loss of the entire field. So the description that fits best is central vision loss with preserved peripheral vision. Think of it as losing the focus in the center while the edges stay clear. This differs from losing peripheral vision (tunnel vision), which would indicate a problem outside the central retina; complete blindness would imply no light perception at all, and normal vision would obviously not reflect the central deficit seen in macular degeneration.
