Definition of Amsler Grid

Amsler GridAmsler Grid is a basic test to detect or monitor the progression of age-related macular degeneration (armd), a condition in which the macula, the area on the retina responsible for fine detail vision, deteriorates.

The Amsler grid is a square with evenly spaced horizontal and vertical lines, and a dot in the center of the grid.

The grid’s four corners and lines should appear visible, straight, and intact.

Wavy lines, gaps in the lines, or missing segments suggest damage to the macula. Such a result requires further examination from an ophthalmologist who specializes in retinal disorders.
