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.
If you have dry AMD, check your vision in each eye every day or
as often as your doctor advises. It only takes a few seconds.
Cover one eye. Then, using your other eye, look at the first grid. Repeat
with the opposite eye covered. Call your doctor immediately if you see either
of the following:
Lines that 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.
The distortion or blind spot (scotoma) you
actually see may be different from what is shown in the grid picture.
