Amsler grid testing
Amsler grid testing :
This test is done in selected group of patients depending upon their symptoms. The test involves looking at a chart that has a grid drawn with a central dot. The test is done using the near vision glasses (if one is using the same). The test permits the evaluation of function of the central 20 degrees of the retina.
The patient is asked to look at the central dot and tell whether
All the corners of the chart are seen All the lines are seen straight and not crooked There are any areas of gray patches where the lines are not seen. Whether the central part of the chart or the peripheral part of the chart is clear. The Amsler's chart is very useful as a home monitoring device. If any defect is noted, immediate ophthalmologic examination is warranted.
