The full, normal range of the visual field extends approximately 120 vertically and a nearly 160 horizontally. When severe field loss in advanced glaucoma is present, change to a 10-2 pattern to allow for more accurate assessment of the remaining visual field. When severe field loss in advanced glaucoma is present, change to a 10-2 pattern to allow for more accurate assessment of the remaining visual field. GHT outside normal limits is displayed when at least one zone is at p <1%.

Abnormally high sensitivity is a red flag and indicates low reliability (usually associated with a high rate of positives). This is called a "static" test because the lights do not move across the screen, but blink at each location with differing amounts of brightness. This is generally considered a cosmetic procedure and reduces the appearance of "bags" under the eyes.
