We studied 207 glaucoma patients (207 eyes) who had two successive visual tests on the Humphrey Field Analyzer to determine the association of unreliability (> 10% incidence of a missed catch trial test) with threshold variation. We found that in patients where one visual field showed > 30% false negative or positive errors, and the other visual field also was unreliable, a significant increase in the variance of the mean defect existed from reliable patients (p < 0.05). Of patients who had only one of two visual fields which was unreliable (from false negative errors), only those with marked glaucomatous visual field loss (< -15 dB depth of defect) showed a greater variance in mean defect between examinations over reliable patients (p < 0.05). In total, 41 patients (19.8%) had unreliable visual fields associated with statistically increased threshold variation. This study suggests that patient reliability should be considered when interpreting changes in threshold between automated visual field examinations.
我们研究了207例青光眼患者（207只眼），这些患者在汉弗莱视野分析仪上进行了两次连续的视力测试，以确定不可靠性（漏检试验测试发生率>10%）与阈值变化之间的关联。我们发现，在一个视野显示>30%假阴性或阳性误差且另一个视野也不可靠的患者中，与可靠患者相比，平均缺损的方差显著增加（p<0.05）。在两个视野中只有一个不可靠（因假阴性误差）的患者中，只有那些有明显青光眼视野缺损（缺损深度<-15 dB）的患者，与可靠患者相比，检查之间平均缺损的方差更大（p<0.05）。总共有41例患者（19.8%）的视野不可靠，且阈值变化有统计学意义的增加。这项研究表明，在解释自动视野检查之间阈值的变化时，应考虑患者的可靠性。
