【摘要】　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2/1 000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1/1 000视标方可查到同样缺损者16只眼（62%）；43只眼在视野屏上查出青光眼视野缺损，采用FVFA检查发现视野缺损范围更广泛。结论　表明FVFA视野检查仪较单点动态视野检查更易查到早期青光眼的视野缺损。

　　【Abstract】　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.

　　随着科学技术的发展，青光眼的检查及诊断已有不少的方法，但是对于青光眼所造成的视功能损害的范围、程度以及这种损害进展的追踪观察，仍以视野检查结果为依据进行分析和判断。近年来，由于静态多点或单点刺激视野计的广泛应用，提高了视野检查在青光眼临床诊断中的精确性。因此，我们采用国外已广泛应用的多点静态定量视野分析仪（Friedmann visual field analyser, FVFA ）与视野屏动态、定量检查方法，对青光眼患者进行视野检查，目的在于通过较全面的检查，了解视野改变对青光眼的诊断意义［1，2］。
