What happens at an adult glaucoma screening?
POB uses visual field testing to screen for glaucoma. It is not the air "puff" test. A visual field test measures an individual's entire scope of vision, including peripheral (side) vision, which is affected by glaucoma.
During the test, the patient must look straight ahead at all times to avoid testing the central vision rather than the periphery. Each time a flash of light or movement is perceived, the patient responds by pressing a button. This process produces a computerized map of the visual field.
