To determine whether the pattern electroretinogram can improve the objectivity of visual field assessment, 39 patients with glaucoma and ocular hypertension were studied. This was to establish whether there is a correlation between the pattern electroretinogram and the global indices (mean deviation and corrected pattern standard deviation) provided by automated perimetry using the Humphrey visual field analyser. A significant correlation was found between the amplitude of the P50 + N95 wave of the pattern electroretinogram and the mean deviation and corrected pattern standard deviation components of the visual field. The larger the deviation from normal of these indices, particularly the corrected pattern standard deviation, the smaller the amplitude of the pattern electroretinogram. This correlation between the pattern electroretinogram and visual field indices provides an additional measure of confidence when interpreting equivocal results of automated perimetry.
为了确定图形视网膜电图是否能提高视野评估的客观性，对39例青光眼和高眼压症患者进行了研究。目的是确定图形视网膜电图与使用 Humphrey 视野分析仪进行自动视野检查所提供的总体指标（平均偏差和校正模式标准差）之间是否存在相关性。发现图形视网膜电图的P50 + N95波振幅与视野的平均偏差和校正模式标准差成分之间存在显著相关性。这些指标偏离正常的程度越大，尤其是校正模式标准差，图形视网膜电图的振幅就越小。图形视网膜电图与视野指标之间的这种相关性为解释自动视野检查的模糊结果时提供了额外的可信度衡量标准。
