The first line of defense for macular degeneration is awareness. A simple test of your vision will alert you to any changes that may indicate a problem with macular degeneration or a worsening of your condition. This common test is known as the Amsler Grid.
The Amsler Grid looks like graph paper, with dark lines forming a square grid. 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.
Here’s how to use the graph below. Wear your reading glasses, if you normally use them and sit about 14 inches away from the screen. Focus on the dark dot in the center of the grid. While looking at this dot, you still should be aware of the lines of the grid. If you notice any blurred, wavy or missing lines, contact your ophthalmologist as soon as possible.
