# Amsler grid eye test

The Amsler grid is a simple test used to check for distortion or missing areas in central vision, particularly in macular disease. It consists of a square of intersecting lines with a central fixation dot.

## How to use it

The test can be performed at home or in clinic.

- Wear reading glasses if needed and cover one eye
- Fixate on the central dot at reading distance
- Note any wavy, blurred, or missing areas on the grid
- Repeat with the other eye and report new changes promptly

## Clinical role

The Amsler grid is a monitoring rather than a diagnostic tool.

- Useful for patients with age-related macular degeneration or other macular conditions
- Helps detect early conversion from dry to wet AMD
- Abnormal results prompt urgent comprehensive macular assessment
- Should be used regularly as advised by an eye-care professional
