The Amsler grid is a sensitive test that can detect early damage to the macula. It is especially useful for monitoring patients with age-related macular degeneration.

- Post the Amsler grid in a place where you will see it frequently, such as on a refrigerator or a bathroom mirror.
- Hold the grid at a comfortable reading distance-about 14 inches.
- If you normally wear glasses or bifocals to read, these should be worn while checking an Amsler grid.
- Cover one eye and focus on the black dot in the center of the grid. The lines should all look straight and the boxes should all look square.
- Note any vision changes such as a dark spot or wavy lines.
- Repeat these steps with the other eye.
- If you notice a new area of distortion or dark spot, contact your eye doctor.
