What is Amsler Grid Test?
One of the easiest ways to screen for age-related macular degeneration (AMD) is to use an Amsler grid. An Amsler grid is a chart with lines and a dot at the center. Your doctor can give you one to use at home.
Cover one eye. Then, using your other eye, look at the first grid. Repeat with the opposite eye covered. Call your doctor immediately (702-896-6043), if you see either of the following:
Lines appear wavy and curved.
A blank or dark spot—other than the center dot—in the middle of the grid.
In the second grid, the lines around the center are wavy and distorted. This is one example of how the straight lines in the grid above might appear to someone with Macular Degeneration.
