Abstract
The reproducibility of perimetrie results on the blind spot has been investigated under controlled conditions using the kinetic perimetry of Goldmann and the computerized static perimeter of Krakau-Heijl. At defined time intervals kinetic perimetry was performed twice by two independent well-trained perimetrists on 178 eyes of 107 patients; the same eyes and patients were examined twice with the computer perimeter as well. Perimetrie results obtained from 158 eyes were considered for statistics. There was qualitative agreement based on the alternative ‘normal’ or ‘pathological’ in kinetic perimetry in 74% of the double examinations and in 89% in computer perimetry. Identical size of the blind spot in repeated examinations was found in 34% with the Goldmann perimeter and in 78% with the computer perimeter. Observer variability of the static computer perimetry of the blind spot was compared with the variability of the results on the rest of the central visual field.
