The Visual Field Test is a painless test used to detect subtle damage to your peripheral or central vision. It takes approximately 20 minutes. The patient looks at a screen and responds by clicking a button when flashes of light are seen. It is most commonly used for early detection of glaucoma, diseases of the optic nerve, and toxicity to the macula.
