Automated Perimeter testing provides accurate assessment of which aspects of the visual field?

• A. Central vision only
• B. Peripheral vision only
• C. Color vision
• D. Central and peripheral visual fields

Answer: (D)

Automated perimeter testing measures how sensitive each part of the visual field is to light across the entire field of view, from the center outward to the periphery. It presents light stimuli at many locations and records the threshold at which the patient detects them, creating a map of sensitivity for both central and peripheral areas. This means it can identify issues in the central vision, which is crucial for detailed tasks, as well as in the peripheral vision, important for awareness and motion detection. Color vision, on the other hand, isn’t assessed by standard visual field testing; perimetry focuses on light sensitivity rather than color discrimination. So this type of testing provides an accurate assessment of both central and peripheral visual fields.
