The Amsler Grid test detects image distortions and variations in retinal sensitivity.
These abnormalities correlate with anatomical changes in the macula in diseases like macular degeneration, diabetic retinopathy or macular pucker.
When taking this test, hold the device 14 inches (36 cm) from your eyes. If you use glasses for reading wear them during the test. Make sure the screen is clean.
