Amsler Grid — Macular Health Self-Check
Spot wavy or missing lines that may suggest macular changes.
What this test measures
The function of your macula — the small central area of the retina that handles sharp, detailed vision used for reading and recognising faces.
Why it matters
Macular conditions like age-related macular degeneration often start silently. Wavy lines or missing squares on the Amsler grid can appear before any noticeable drop in vision.
Who may benefit
Anyone over 50, people with a family history of AMD, diabetics, smokers, and patients already monitoring an existing macular condition. Dr. Roxanna Gangi recommends a baseline exam to interpret your results in context.

For an accurate assessment, request a comprehensive exam with Dr. Roxanna Gangi, your trusted Optometrist in Toronto and York Region.
How to take this test
- If you wear reading glasses, put them on.
- Hold your screen about 30 cm (12 inches) from your face.
- Cover one eye. With the other eye, stare at the centre dot.
- While focused on the dot, notice if any lines appear wavy, blurry, missing or distorted.
- Repeat with the other eye.
Take the test
Did some lines look wavy, blurry, missing or distorted? These can be early signs of macular issues. Book an exam with Dr. Roxanna Gangi for a proper assessment.
