近年来,国外对青光眼的视野检查及其视功能研究一直很活跃。定量视野的应用是近年来青光眼视野研究深入的一个重要标志。只有精确的视野检查才能保证准确地从群体中检出青光眼病人。定量视野,尤其是定量阈值视野检查不仅能使我们测定不同视域的光敏阈值的变化,而且又能确定阈值降低的程度。用阈值变化定量描述视野的变化,给我们以更多的视野变化的信息,对青光眼的视野缺损的检出也较以前提早。因此本文研究的目的是初步探讨Friedmann Analyzer MⅡ中心定量视野仪检查的
In recent years, foreign glaucoma visual field examination and visual function research has been very active. Quantitative visual field application in recent years, glaucoma field of vision is an important sign of in-depth study. Only accurate visual field examination can ensure accurate detection of glaucoma patients from the population. Quantitative visual fields, especially quantitative threshold visual field tests, not only enable us to measure changes in the threshold of light sensitivity in different fields of view, but also to determine the extent of threshold reduction. Quantitative description of changes in the field of view with threshold changes gives us more information on the visual field changes and the detection of glaucomatous visual field defects is also earlier than before. Therefore, the purpose of this study is to investigate the Friedmann Analyzer M Ⅱ central quantitative field of vision
