What home-monitoring tool is used to track stability in age-related macular degeneration?

• A. Snellen chart
• B. Visual field test
• C. OCT at home
• D. Amsler grid

Answer: (D)

In age-related macular degeneration, you want a simple way to watch for changes in central vision, especially distortion and small blind spots in the macula. The Amsler grid does exactly that. It’s a basic square grid with a central fixation point that you view with one eye at a time. If any lines appear wavy, distorted, blurred, or if parts of the grid look missing, that can signal a change in the macula that might mean progression or instability. It’s easy to use daily at home, doesn’t require special equipment, and focuses on the part of vision AMD affects most.

By contrast, a Snellen chart tests how well you can see at a distance, not the integrity of the central retina where AMD causes trouble. A visual field test maps peripheral vision, which isn’t the area most impacted early in AMD. A home OCT isn’t readily available for consumer use and imaging the retina at the clinic with OCT provides structural detail rather than a simple, ongoing functional check you can perform daily. So for tracking stability and detecting new changes quickly at home, the Amsler grid is the most practical and informative tool. If new distortion or a sudden change is noticed, it’s important to contact a clinician promptly.
