[Variation of sensitivity in the central visual field by the range of measurement]

We compared two programs with different measurement field ranges in terms of sensitivity for common coordinates using an automated perimeter Octopus. The combination of programs consisted of programs 31 and 61, 31 and PSQ, 61 and 11, 61 and PSQ. The center of program 61 was (0, 0). PSQ was made by the sargon program and a program which measured the outer 16 points of the 61. The mean sensitivity of the common coordinates in 11 was significantly better than that in 61, which was better than that in 31, and that in PSQ better than that in 31 and in 61. The sensitivity was better in programs which tested a smaller size of measurement in the central visual field.
