[Quantitative perimetry for early diagnosis of open-angle glaucoma]

105 eyes were examined with the OCTUPUS 2000R automated perimeter. Of 19 glaucomatous eyes with abnormal visual fields by arc perimeter and campimeter, all showed field abnormalities by the quantitative perimetry, the defects being mostly of the mixed type (13/19), in the medium stage (10/19). Among 48 eyes of glaucoma or suspected glaucoma with normal visual fields by arc perimeter and campimeter, 33 showed field abnormalities by the quantitative perimetry, the defects being mostly of the mixed and diffuse type (29/33), in the early minor stage (23/33). The characteristic field defects were mostly sectorial and arcuate scotomata and some in the form of nasal steps. Among 38 normal eyes, minor local or diffuse field defects were found in 6 eyes.
