Numerical printouts of 23 visual field examinations performed with glaucoma program G1 were analyzed by 3 perimetrists. The task consisted of defining the existence of clusters or scotomas. Considerable discrepancy with regard to the existence or the size of clusters and/or scotomas was found among the three perimetrists. The median difference in number of clusters as compared for each pair of interpreters was found to differ from zero at a significance level of 5% (Wilcoxon's signed-rank nonparametric test). These findings suggest that the interpretation of a visual field status by human observers will always remain subjective and to a large extent contradictory. This situation calls for the implementation of interpretative computer software to supplement the currently available algorithms.
3名视野检查医师对使用青光眼程序G1进行的23次视野检查的数值打印结果进行了分析。任务包括确定簇状缺损或暗点的存在。在这三名视野检查医师之间，发现对于簇状缺损和/或暗点的存在或大小存在相当大的差异。每对解释者比较的簇状缺损数量的中位数差异在5%的显著性水平上与零不同（威尔科克森符号秩非参数检验）。这些发现表明，人类观察者对视野状态的解释将始终保持主观性，并且在很大程度上相互矛盾。这种情况需要实施解释性计算机软件来补充当前可用的算法。
