The Amsler vision test examines the retina. The objective is early detection of diseases in the center of the retina (macula). With macular degeneration, only the central visual acuity of the eye is completely or partially lost since only the center of the retina is affected, the visual field on the sides remain unaffected.
The Amsler Grid is a simple test you can perform regularly to monitor your vision and detect changes in your visual acuity early to enable treatment at an early stage.
It’s easy to perform the test using the Amsler grid:
- Wear your reading glasses and look at the grid at the normal reading distance (approx. 30-50 cm).
- Cover one eye.
- Focus on the black dot in the center of the grid.
- Check whether all lines of the grid are straight or whether they are distorted, blurred or unfocused in specific areas of the grid.
- Repeat the process with the other eye.
- If lines appear curved or squares are hidden, please see your ophthalmologist and describe your observations.
- The test should be repeated at regular intervals (twice a month).
