Representative plot of each point tested for (A) paracentral visual field loss, (B) cecocentral visual field loss, and (C) peripheral visual field loss in 3 right eyes. (A) The blue boxes indicate the central/paracentral visual field loss regions. A cluster of 3 or more points with sensitivity of −5 dB or more within the central 9 degree of visual field or a single point with P less than 0.5% represents a paracentral visual field loss. (B) Cecocentral scotoma were characterized by a cluster of 3 or more points with sensitivity of −5 dB or more including at least the visual field points indicated by numbers 33 and 41 together or 34 and 42 together. (C) The colored boxes indicate each possible peripheral visual field loss region, including nasal step (orange), temporal wedge (green) and arcuate patterns (red). A cluster of 3 or more points with sensitivity of 5 dB or more in any of these regions represents a peripheral visual field loss pattern. There is overlap between the paracentral zone and arcuate areas, consisting of the second row of points. For the arcuate area to be considered involved, there must be at least 1 point in the third row from the top or bottom that has a retinal sensitivity of 5 dB or more.
