多点静态定量视野计检查开角型青光眼

目的 比较采用多点静态定量视野分析仪（Ｆｒｉｅｄｍａｎｎ ｖｉｓｕａｌ ｆｉｅｌｄ ａｎａｌｙｓｅｒ,ＦＶＦＡ）与中心平面视野屏检查视野在青光眼诊断中的作用。方法 应用两种视野计对４８例（９５只眼）开角型青光眼患者进行视野检查。结果 ２６只眼在视野屏上用２／１０００视标查出小的视野缺损,而用ＦＶＦＡ检查出完全相似者２３只眼（８８％）;２６只眼在ＦＶＦＡ查出早期青光眼视野缺损,而在视野屏上必须用１／

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
