Poly-static quantitative perimetry for detection of open angle glaucoma
Lai Z; Lao Y; Ai FChinese Journal of Ophthalmology 2000; 36: 129
OBJECTIVE: To evaluate the sensitivity of poly-static quantitative perimetry for the detection of visual field defects in open-angle glaucoma. METHODS: Forty-eight patients (95 eyes) with open-angle glaucoma were examined by poly-static quantitative perimetry (Friedmann visual field analyzer (FVFA)) and dynamic perimetry (tangent screen), respectively. RESULTS: Twenty-six eyes showed a small defect of the visual field on the tangent screen with 2/1000 visual size, and 23 eyes (88%) showed the same defects when checked with FVFA; visual field defects of early-stage glaucoma were found in 26 eyes when checked with FVFA, but only 16 eyes showed the same defects on the tangent screen with 1/1000 visual size; the visual field defects of 43 glaucomatous eyes on the tangent screen were found to be larger when they were checked with FVFA. CONCLUSION: Compared with dynamic perimetry, poly-static quantitative perimetry is more sensitive to detecting visual field defects in early-stage glaucoma.LA: Chinese
