This information is not designed to replace a physician’s independent judgment about the appropriateness or risks of a procedure for a given patient. Early diagnosis and treatment is important with MD, and even a month or two can make a difference. If you notice any changes in your visual field or how you see things, call your doctor – even if you just had an eye exam.
They are often part of the larger comprehensive dilated eye exam, and the Amsler grid is something you can do at home to monitor your progression. The visual acuity test and Amsler grid are just two of the tools that your eye doctor will use to help him/her make the diagnosis of macular degeneration. It’s recommended to check your eyes with the Amsler grid once a week put it somewhere easily accessible or visible such as on the refrigerator to serve as a reminder. Any change from that is a signal that something may be awry. What you see at that visit is your baseline. In order to get your baseline for the Amsler grid, when you go to the doctor, look at the grid. This may be from fluid or blood that has built up under the retina. An eye that has wet AMD or "wet" myopic macular degeneration will typically see some curved lines or an area that has a gray or black spot. But if the waviness gets worse, that could signal progression of disease, and you should call your doctor. If you see a little waviness of the lines, that could be from drusen that have built up under the retina causing small distortions in the retina. When you go to the doctor, you can ask her for one to take home with you. It looks like graph paper, but there’s a small dot in the center of the grid. It is a grid with black lines on a white background, although sometimes it’s white lines on a black background. The Amsler grid is a tool that is not only used during an eye exam for diagnosis, but can also be used to monitor progression of disease, track visual changes associated with transition from dry to wet AMD, and can also be used at home to monitor for changes in vision such as new blind spots or metamorphopsia (wavy lines). The process is then repeated with the other eye. 2 You will either cover one eye with your hand or use a paddle to cover one eye while you read the smallest line you can clearly see with the uncovered eye. If it’s been done less than 20 feet away from you, a special chart will be used to account for this. It’s done with either a standardized chart (called a Snellen chart) or on a video monitor, and you may be asked to remove your glasses or contact lenses. The test itself is done right in the doctor’s office, and is the “eyechart test” you probably think of when you think of vision testing. It is merely one part of the eye exam and does not determine visual function (your ability to perform visual tasks and activities). This does not take into consideration peripheral vision, ability to focus, depth perception, color vision, or anything else, except for how clearly you can see something at a distance. Even if you have 20/20 vision, this doesn’t mean your vision is without problems.
