The Amsler Grid is is a grid of horizontal and vertical lines used to monitor a person's central visual field.  The grid was developed by Marc Amsler, a Swiss ophthalmologist. It is a diagnostic tool that aids in the detection of visual disturbances caused by changes in the retina, particularly the macula, as well as the optic nerve and the visual pathway to the brain. The Amsler Grid is used to help detect defects in central 20 degrees of the visual field. In the test, the person looks with each eye separately at the small dot in the center of the grid. Patients with macular disease may see wavy lines or some lines may be missing.
