[The perimetry of the blind spot. A comparison of kinetic and static, computerized stratgies]

The reproducibility of perimetric results on the blind spot has been investigated under controllnt well-trained perimetrists on 178 eyes of 107 patients; the same eyes and patients were examined twice with the computer perimeter as well. Perimetric 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.
