Amsler Grid Testing

Amsler grid testing is a very sensitive method of detecting early changes in your central vision. Detection of retinal diseases, such as macular degeneration, in its early stages may prevent serious loss of vision.

  1. Place the Amsler grid in a convenient place approximately 18 inches away, or normal reading distance.
  2. Check each eye separately while covering the other eye. If you wear glasses for reading, use them during this test.
  3. Look directly at the black dot in the center of the grid. Use your side vision to see the other lines of the grid without moving your focus from the center dot.
  4. Note any irregularities of the grid patter such as bent, fuzzy, or wavy lines or dark or missing spots. Draw these on the printed grid and date them.

If you notice a change in your vision on the Amsler grid test, you should contact us. Particular attention should be given to sudden changes.
