Amsler Grid Test

Abstract

The Amsler grid demonstrates particular utility in detecting early manifestations of age-related macular degeneration (AMD), central serous chorioretinopathy, and other maculopathies by identifying metamorphopsia, scotomas, and other central vision abnormalities. While the test shows high sensitivity for moderate to severe macular changes (sensitivity 78.5%, specificity 85.6%), its effectiveness is notably dependent on patient compliance and proper administration.

Instructions

Position yourself at a normal reading distance from the screen
If you wear reading glasses, put them on
Cover one eye
Focus on the central dot
While keeping your focus on the dot, notice if:
- Any lines appear wavy or distorted
- Any areas appear blurry or missing
- All corners and sides of the grid are visible
Repeat the test with your other eye

Important: This is for educational purposes only. If you notice any distortions or changes in your vision, consult an eye care professional immediately.

The Amsler grid is a fundamental diagnostic tool used to detect and monitor changes in central vision, particularly for conditions affecting the macula such as:

Age-related macular degeneration (AMD)
Macular edema
Central serous chorioretinopathy

Key points about the Amsler grid test:

Purpose:

Early detection of vision changes
Regular monitoring of known conditions
Self-monitoring between professional eye exams

What it detects:

Metamorphopsia (distorted vision)
Scotomas (blind spots)
Central vision defects

Advantages:

Non-invasive
Quick to administer
Can be done at home
Sensitive to early changes

Limitations:

Only tests central 10° of vision
Subjective test
Requires patient cooperation and understanding
Not a replacement for comprehensive eye exams
