Profile: The Peristat Group, Inc. specializes in offering AC-powered automatic perimeter and Amsler grid. The Amsler grid is a simple screening test that is used to assess the macula (the center of the retina). It consists of evenly spaced horizontal and vertical lines printed on a black or a 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.
