An amsler grid gives first indications of a visual field loss. Learn more about this test and how it works.

Amsler grid

On Amsler Grid is a simple test to detect early on whether the so-called yellow spot (macula) on the retina is still intact. If this is not the case, it is called a macular degeneration. This manifests itself by failures in the central field of vision, and one perceives images distorted. Read here what the Amsler grid really is and how the Amsler test works.

What do you do with the Amsler grid test?

The Amsler grid is a very simple diagnostic tool: It consists of a square, fine-mesh grid with black lines on a white background. In the middle of the grid is a black dot. The ophthalmologist places the Amsler grid at a distance of 30 to 40 centimeters from the patient and asks him to cover one eye with his hand. In younger children, of course, take over the parents. The patient should now fix the point in the middle of the Amsler grid with the other eye. The doctor asks the patient the following questions:

  • Are the dot in the middle or other lines out of focus?
  • When fixing the center, do you see all the corners and sides of the large grid square?
  • Do you see holes in the black lines?
  • Are all lines straight and parallel and are the small squares even?
  • Do you see colors, shades or movements like waves in the picture? (Deformation)
  • If so, how many squares are between this area and the center?

With these simple questions, the physician can detect visual field defects that develop early on destruction of the yellow spot. In addition, he can judge the extent of the disease based on the distance of midpoint and deformation. The second eye is then tested in the same way.

Self-test with the Amsler grid

Because the Amsler test is easy to perform and does not pose any dangers or side effects, you can easily make it at home for self-examination. An Amsler grid, for example, is available on request from your ophthalmologist. But you can also easily download free templates on the Internet if you suspect a macular degeneration.

Remember, however, that blurred vision in the Amsler Grid not only occur in the case of damage to the yellow spot: Other diseases of the retina can also lead to abnormalities in the Amsler test. Therefore always consult your ophthalmologist if you have noticed a visual disturbance during the self-test.

For these diseases, the examination is important

  • macular degeneration
  • Retinitis pigmentosa
