[Planimetric evaluation of kinetic perimetry with the Goldman perimeter (author's transl)]
Abstract:
Kinetic perimetry was performed on 12 normal subjects. The perimetric results obtained with a Goldmann perimeter by 12 different investigators were statistically analyzed. Planimetry of areas outlined by a given isopter was done in order to reduce the amount of data. This led to a reduction in standard deviations of almost 50 percent. The statistical significance of field changes depends on individual variation and frequency of testing. If standard deviations are calculated in dB, variation becomes independent of given isopters. However, standard deviation may be increased by a factor of almost 2 as a result of the influence, of the investigator. Therefore, a standardization of test procedures by automatization seems meaningful, although standard deviations will not necessarily be lower with computerized perimetric methods.
