The Amsler Grid

This is a test you can do at home.  This simple screening test is used to assess the macula (the center of the retina).  The Amsler Grid consists of evenly spaced horizontal and vertical lines printed on black or white paper.  A small dot is located in 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.

• 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 grid do not appear straight and parallel or there are missing areas, make an appointment with yourt eye doctor.     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.
