The Amsler Grid is used by eye doctors to detect vision changes that may result from damage to the macula (the central part of the retina). Any damage to the macula can result in the straight lines of the grid to appear broken, wavy, or distorted.
This chart can be very useful to test for any macula change; however, it is not a replacement for regular comprehensive exams with your eye doctor.
How To Use The Amsler Grid
- Hold the Amsler Grid at eye level and at a comfortable reading distance, about 12-14 inches from your face.
- Wear the glasses or contacts you normally use for reading.
- Cover one eye.
- Fix your gaze on the center black dot.
- Make note if any portion of the grid is wavy, blurred or missing.
- Repeat with the other eye.
What Should I See?
Patients with a healthy macula should see grid lines that are straight and a visible central dot. Patients with macula damage may see parts of the grid as wavy or distorted. There may even be missing areas of lines.
