Amsler grid test: Age related macular
The Amsler grid is a chart that optometrist or ophthalmologist use to detect vision problems from damage to the macula or the optic nerve. As all you you know that the macula is central part of retina.
The damage caused by macular degeneration, macular scotoma or other eye diseases, so the Amsler grid is useful in detecting these problems.
An early diagnosis means early treatment, so it may help to limit or at least slow the vision loss you experience.
x 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 regular visits to your optometrist, because you can easily miss signs that only a trained eye care practitioner will find.
The chart is an approximation of the printed chart used by optometrst. For more accurate detection of macular damage, you will need a complete eye exam.
How to Use The Amsler Grid Test
Testing your eyes with an Amsler grid is easy and takes only a few minutes.
1. Test your eyes under normal room lighting used for reading.
2. Wear eyeglasses you normally wear for reading.
3. Hold the Amsler grid approximately 14 to 16 inches from your eyes.
4. Test each eye separately: put your hand over one eye while testing the other eye.
5. Keep your eye focused on the dot in the center of the grid and answer these questions:
Do any of the lines in the grid appear wavy, blurred or distorted?
Do all the boxes in the grid look square and the same size?
Is there any "holes" (missing areas) or dark areas in the grid?
Can you see all corners and sides of the grid (while keeping your eye on the central dot)?
6. Switch to the other eye and repeat.
IMPORTANT — Report any irregularities to you visit your optometrist immediately. Mark areas of the Amsler grid that you're not seeing properly (print two grids if you notice problems in each eye), and bring the grid(s) with you when you visit your optician.
Check your eyes with the Amsler grid as frequently as your optometrist recommends, or whenever you notice a significant change in your vision.
