Visual field testing

A visual field test is an examination that may be performed to analyze a patient’s visual field. The test may be performed by a technician directly, with the assistance of a machine, or completely by an automated machine. Machine based tests aid diagnostics by allowing a detailed printout of the patient’s visual field. See Perimetry
