[Poly-static quantitative perimetry for detection of open angle glaucoma].

Objective To evaluate the sensitivity of polystatic quantitative perimetry for the detection of visual field defect in open angle glaucoma Methods 48 patients (95 eyes) of open angle glaucoma were examined with polystatic quantitative perimetry [Friedmann visual field analyzer (FVFA)] and dynamic perimetry (tangent screen) respectively Results 26 eyes showed small defect of visual field on tangent screen with 2/1 000 visual size, and 23 eyes (88%) showed the same defects checked with FVFA; visual field defects of early stage glaucoma were found in 26 eyes checked with FVFA, but only 16 eyes showed the same defects on tangent screen with 1/1 000 visual size; the visual field defects of glaucoma on tangent screen in 43 eyes were found larger when they were checked with FVFA Conclusion Comparing with dynamic perimetry, polystatic quantitative perimetry is more sensitive to detect visual field defect of early stage glaucoma
