Amsler Grid

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.
