Patient evaluations for scotomas should include which of the following screening tests?

• A. Amsler grid
• B. Visual acuity
• C. Color vision testing
• D. Confrontation testing

Answer: (A)

The Amsler grid is specifically designed to assess central visual field disturbances and is a critical tool in identifying scotomas, which are localized areas of vision loss. When a patient looks at the grid, any distortions or blank areas may indicate damage to the retina or the optic nerve, particularly associated with conditions like macular degeneration. The test is straightforward and can be performed easily during an eye exam, making it very effective for monitoring changes in vision related to scotomas. While visual acuity measures the clarity or sharpness of vision, it does not specifically test for scotomas. Color vision testing evaluates the ability to distinguish colors but does not provide information about blind spots in the visual field. Confrontation testing assesses peripheral vision in a rudimentary manner, but it is less effective for detecting central visual field issues directly related to scotomas. The Amsler grid stands out as the best choice because of its targeted approach to identify and evaluate central vision loss effectively.
