Which test is used to measure the visual field?

  1. All motion in every direction is stopped when the light is moved across the pupil

  2. The patient fixates with only one eye while the other eye turns in

  3. The area of the space visible to the eye

  4. Perimetry

The correct answer is: Perimetry

Perimetry is a widely used test to measure the visual field. It involves the patient looking at a target in the center of a screen while small lights in the periphery are turned on and off, and the patient responds when they see the lights. A and B may seem like possible options, but they describe specific parts of the test rather than the actual name of the test. C is not a specific test for measuring visual field and is a more general description of the concept.
