Which type of visual field test maps the entire visual field by testing central and peripheral vision?

• A. Manual kinetic perimetry
• B. Automated static perimetry
• C. Chromatic perimetry
• D. Threshold perimetry

Answer: (B)

Visual field mapping relies on how stimuli are presented across the field and how responses are recorded. Automated static perimetry achieves a full-field map by presenting light stimuli of fixed brightness at many predefined locations that span from the center of gaze to the far periphery. By systematically varying the brightness to find the threshold at each point, it creates a detailed, quantitative map of sensitivity across the entire visual field. This method covers both central vision, crucial for sharp vision, and peripheral regions, making it ideal for detecting widespread or localized field loss in diseases like glaucoma or optic neuropathies. In contrast, kinetic perimetry uses moving targets and is more operator-dependent, outlining isopters rather than providing a dense, standardized threshold map. Chromatic perimetry targets color sensitivity rather than full luminance sensitivity, and while threshold perimetry is a broader concept, the automated static version is specifically designed to map the full field in a consistent, repeatable way.
