SAP is a computerized, threshold static perimetry that tests the central visual field with a white stimulus on a white background. 4. False Negatives This is when the patientat first responds to a dim light, but later in the test does not respond to a brighter light in that same location. Know if a test is reliable; fixation losses greater than 20% can indicate poor reliability, but improper mapping of the blind spot can cause false elevation of this index.
