The visual field test is a subjective measure of central and peripheral vision, or “side vision,” and is used by your doctor to diagnose, determine the severity of, and monitor your glaucoma. The most common visual field test uses a light spot that is repeatedly presented in different areas of your peripheral vision.
The Humphrey Visual Field is a special automated procedure used to perform perimetry, a test that measures the entire area of peripheral vision that can be seen while the eye is focused on a central point.
A simple, basic visual field test is performed by having the patient look straight ahead and count the fingers shown by the doctor from each side. However, visual fields are typically measured by a computer in an optometrist's or ophthalmologist's office.
Visual field results are interpreted to establish artifact from disease to account for an abnormal test. Some patients will have a completely normal test, while others will show a visual field loss that is in one or both eyes).
