Which of the following is NOT a visual field test used in VR?

• A. Autorefractor
• B. Confrontation
• C. Amsler Grid
• D. Central California Screener

Answer: (A)

The main idea is telling apart tools that map or screen the visual field from those that measure refractive status. A visual field test looks at how much of the environment a person can see across the entire field, from center to periphery, so it helps detect gaps or losses in vision. An autorefractor, in contrast, uses light to measure how the eye focuses and gives an eyeglass prescription; it does not assess how wide or where the field of vision is, so it doesn’t test the visual field. Among the others, a confrontation test is a quick check of gross peripheral vision by comparing what the patient can detect in the periphery; the Amsler Grid monitors central vision for distortions that indicate macular issues; and the Central California Screener is a standardized field-screen that maps sensitivity across multiple locations. These are all aimed at identifying field issues, unlike the autorefractor.
