OBJECTIVE: To evaluate the sensitivity of poly-static 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 poly-static 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, poly-static quantitative perimetry is more sensitive to detect visual field defect of early stage glaucoma.
