Visual Field Testing

A visual field test, also called Perimetry, measures the sensitivity of a person's central and peripheral vision. There are several types of visual field testing including the Tangent Screen, Goldmann visual fields and automated visual fields. The standard type of visual field test is called automated static Perimetry. In this test, a patient is shown light stimuli of varying intensities in the central and peripheral vision. A person can have perfect 20/20 vision centrally but have peripheral vision loss without even being aware of it. Some causes of peripheral vision loss are glaucoma, retinal disease, and optic neuritis. Some brain tumors can also cause peripheral vision loss. If the visual field test shows vision loss in a characteristic pattern, it can help the eye doctor diagnose the cause of the problem.

Michael Fu, O.D., Optometrist at D’Ambrosio Eye Care tells us “This test can take 5 to 10 minutes per eye and the results are not always consistent. Taking the test more than once is usually necessary to establish a consistent baseline. Periodic testing is usually performed to monitor for any subtle changes over time. Visual field testing can catch vision changes early in the process before significant vision loss occurs and is considered one of the main tests to monitor the visual status in glaucoma patients.”
