Amsler Grid

Amsler Grid Chart Test

An Amsler grid is a checkered pattern with a central dot in the middle of the pattern. The grid is a self-monitoring tool that allows people to check their vision one eye at a time to monitor for blurring or distortion that may signify the conversion from dry to wet AMD. People with AMD progression may notice changes on the Amsler grid, and if this occurs, they should contact their ophthalmologist promptly.

The Amsler Grid Chart should be used to check the central part of your visual field, the area that can be damaged by Macular Degeneration.
