Which statement about the Amsler Grid is true?

• A. It is used to measure intraocular pressure
• B. It tests peripheral fields only
• C. It is used for home monitoring of progressive changes
• D. It detects color vision defects

Answer: (C)

The Amsler Grid is a simple home monitoring tool for central vision, used to detect progressive changes in the macula. By staring at the central dot and noting whether the surrounding lines appear straight and complete, a patient can notice metamorphopsia, scotomas, or blank areas that may indicate worsening macular disease. This makes it ideal for ongoing home surveillance of conditions like age-related macular degeneration or macular edema, so changes can be caught early and discussed with an eye care professional. It isn’t used to measure intraocular pressure, it doesn’t assess the peripheral visual field, and it isn’t a color-vision test.
