Die Reproduzierbarkeit zentraler Gesichtsfeldbefunde bei der kinetischen und der computergesteuerten statischen Perimetrie

Abstract

Under controlled conditions the differences between duplicated examinations with the Goldmann kinetic perimeter and the Krakau/Heijl static computerized perimeter were evaluated. Kinetic visual fields were obtained independently by two well trained examiners and duplicate examinations were performed by computer perimetry. The differences between the two examinations were statistically evaluated using quantitative criteria. The agreement between first and second examination--based on normal and pathologic findings--was 72% for the Goldmann and 88% for the computer perimeter. The greater reproducibility of central visual field testing with the computer perimeter is most probably due to the subjectivity of the observer in the kinetic manual technique. The computer obviously represents a standardized observer using a constant strategy with a fixed time course. The computerized perimeter was easy to operate and did not require a specially trained technician. All the patients in whom kinetic visual field testing was possible were able to undergo computerized perimetry.

Effectiveness of computer‐assisted perimetry in the follow‐up of patients with pituitary microadenoma responsive to medical treatment

“…The specificity (De Natale et al, 1985) and the reproducibility (Gramer et al, 1980) of the CP have been well shown; a 2% interassay CV is found in our experience.…”

Goniodysgenesis in Elderly Glaucoma and Non-Glaucoma Patients. A Masked Biomicroscopic Study of the Anterior Segment

“…The problem with large inter-observer variation has been addressed earlier in the glaucoma field, e.g. regarding optic nerve head evaluations (Kahn et al 1975;Schwartz 1976) and manual perimetry (Gramer et al 1980). We have been unable to find in the literature any slit-lamp or gonio\copic study addressing the issues of inter-observer variation and bias.…”
