What is a visual field test? A visual field test is a method of measuring an individual's entire scope of vision, that is their central and peripheral (side) vision. Visual field testing maps the visual fields of each eye individually and can detect blind spots (scotomas) as well as more subtle areas of dim vision.
This is the first step in the examination for confrontational visual field. This is a non-invasive method of testing. Your doctor may also use a machine to measure your peripheral vision. The automatic perimetry machine is used to perform this test. You will be shown some light flashes in and around your field of vision. You will have access to a button that you will have to press as soon as you are able to see the flash.
