The Amsler grid is a tool that eye doctors use to detect vision problems resulting from damage to the macula(the central part of the retina or the optic nerve. An early diagnosis means early treatment, so it may help to limit or at least slow the vision loss you experience.
One of the first signs of macular degeneration can be wavy, broken or distorted lines OR a blurred or missing area of vision. The Amsler Grid can help you spot these early. Early detection of wet AMD is critical because laser treatment, when indicated, is most successful when performed before damage occurs. Since dry AMD can lead to development of wet AMD, most patients should use the Amsler Grid. Check with your eye doctor to find out how often you should use this test.
