Amsler Grid


This simple screening test is used to assess the macula (the center of the retina). The Amsler Grid consists ofevenly spaced horizontal and vertical lines printed on black or white paper. A small dot is located at the center of the grid for fixation. While staring at the dot, the patient looks for wavy lines and missing areas of the grid. This test is especially helpful for monitoring vision at home.

The doctor is especially interested in the following when testing vision with the Amsler Grid:

  • Are you able to see the corners and sides of the square?
  • Do you see any wavy lines?
  • Are there any holes or missing areas?

If the lines of the grid do not appear straight and parallel or there are missing areas, the doctor will examine the back of the eye (macula) very closely. This test is frequently given to patients for home use to monitor macular degeneration. When using the test at home, notify the doctor if any changes in the appearance of the Amsler Grid are detected.
