Amsler Grid: Test for Macular Degeneration or Other Vision Problems
The Amsler grid is a tool used during an annual comprehensive eye exam that eye doctors use to detect vision problems resulting from damage to the macula (the central part of the retina) or the optic nerve. The damage may be caused by macular degeneration or other eye diseases, so the Amsler grid is useful in detecting these problems.
If you are at risk for macular degeneration or other eye diseases, you can use this chart at home to monitor your vision. But using the chart doesn't mean you should skip annual visits to your eye doctor, because you can easily miss signs that only a trained eye care practitioner will find.
The chart below is an approximation of the printed chart used by eye doctors. For more accurate detection of macular damage, you will need a comprehensive eye exam.
How To Test Yourself with the Amsler Grid
If you need reading glasses, please wear them while you use the Amsler grid. The grid should be at about the same distance from your eyes that any other reading material would be.
Cover one eye, then focus on the dot in the center.
- Do any of the lines look wavy, blurred or distorted? (All lines should be straight, all intersections should form right angles and all the squares should be the same size.)
- Are there any missing areas or dark areas in the grid?
- Can you see all corners and sides of the grid?
- Don't forget to test both eyes
VERY IMPORTANT: Report any irregularity to your eye doctor immediately.
