(AM-zlur): Printed grid (black lines on white background) used as a test for detecting central visual field distortions or defects in macular degenerations.
a grid of 400 small squares (white separated by black lines or black separated by white lines), with a fixation dot in the middle, used to detect macular degeneration in an eye by the presence of “metamorphopsia”—curved, distorted, or broken lines—in the grid
Home eye test featuring equally spaced horizontal and vertical lines in a grid pattern. Used for determining the presence of macular degeneration and other defects that affect central vision. See Age-related Macular Degeneration in Eye Care Encyclopedia.
Graph paper-like grid used in detecting central visual field distortions or defects.
A chart with vertical and horizontal lines used for testing the central visual field (commonly used in assessing age-related macular degeneration).
a chart of uniform squares
a chart that you can use at home to check your vision
a chart that you can use to test your eyes for a change in central vision
a chart with lines and a dot at the center that lets you monitor changes in your central vision
a drawing of vertical and horizontal lines with a dot in the middle
a series of straight lines that run up and down and left to right
a simple pattern of vertical and horizontal lines, with a fixation point in the center to focus on
a useful tool for monitoring your central visual field
A handheld chart featuring equally spaced horizontal park and vertical lines, usually white on black background, used to detect central visual field defects.
A graph paper-like grid that patients can use to monitor for changes in their macular degeneration.
A grid with a dot in the center, used to test for symptoms that may signify macular degeneration.
A chart featuring horizontal and vertical lines used to test vision.
a diagram of squares used to assess vision. Defects in the central visual field (e.g., due to CMV retinitis) may be detected as breaks or unevenness in the lines of the grid.
A special grid (looks like graph paper) in which an individual may determine whether there is any distortion to vision. Given to those who are at risk of macular swelling or neovascularization.
a grid chart used for checking distortion in the vision and central vision defects
(AM-slur). Test card. Grid (black lines on white background or white lines on black background) used for detecting central visual field distortions or defects, such as in macular degeneration.
A test for macular degeneration and macular function
A visual function test used in low vision to determine the type and degree of central vision impairment (impairment of the macular area). Also used as a tool for detecting changes in central vision.
The Amsler grid, used since 1945, is a grid of horizontal and vertical lines used to monitor a person's central visual field. It is a diagnostic tool that aids in the detection of visual disturbances caused by changes in the retina, particularly the macula (e.g. macular degeneration), as well as the optic nerve and the visual pathway to the brain.
