Which term describes a form of perimetry that is typically automated?

• A. Tangent Field
• B. Automated Perimetry
• C. Amsler Grid
• D. Central California Screener'],

Answer: (B)

Automated perimetry is the form that uses computer-controlled equipment to present visual stimuli at many locations in the field of vision and automatically record the patient’s responses. This setup standardizes the test, using predefined programs and threshold algorithms, which makes the results more consistent and easier to compare across sessions. It commonly yields a detailed map of sensitivity across the visual field and numerical indices like deviation and pattern standard deviation.

The tangent field is a manual method where a tester uses a tangent screen and observes responses, not automated. The Amsler Grid is a simple central vision test used to detect metamorphopsia or macular problems rather than a full-field, automated measurement. The Central California Screener is a quick screening tool for central vision, not the formal automated perimetry process.
