A simple screening tool for macular degeneration and other conditions affecting central vision. Mark any areas where the grid appears wavy, blurry, or missing.
โ๏ธ Screening tool only. This test cannot diagnose macular degeneration. If you notice any distortions, missing areas, or changes compared to previous tests, schedule an appointment with Dr. Khilar promptly.
The grid helps identify changes in your central vision that may indicate retinal conditions.
Straight lines appearing wavy or curved (metamorphopsia) can indicate fluid or swelling in the macula โ a hallmark of wet age-related macular degeneration.
Urgency: New waviness is considered urgent โ see a doctor within days, not weeks.
Dark, blank, or blurry patches (scotomas) suggest damage to the photoreceptors in the macula. May indicate advanced dry AMD or other macular conditions.
Note: Small blind spots can enlarge gradually โ regular testing helps track changes.
If the grid squares appear different sizes or shapes, this may suggest early macular changes, epiretinal membrane, or macular edema from diabetes.
Ophthalmologists recommend testing with the Amsler Grid weekly at home, especially if you're over 50 or have risk factors for AMD.
Tip: Test at the same distance and lighting each time to reliably detect changes.
