摘要目的 评价Humphery Matrix视野计的N-30-F程序与倍频视野计(frequency-doublingtechnology,FDT)N-30程序的检查结果是否具有一致性.方法 对受检眼32例32只眼(原发性开角型青光眼10例10只眼,可疑青光眼患者13例13只眼,正常人3例3眼,高眼压症6例6只眼)进行上述两种视野程序检查,比较两种检查结果的平均偏差(Mean Deviation,MD)、图型标准偏差(Pattern Standard Deviation,PSD)、总体偏差概率图中概率小于5%的缺损点数以及检查所需时间.结果 MD、PSD及总体偏差概率图中概率小于5%的缺损点数,在两种视野程序检查结果间差异均无有统计学意义(分别为P=0.958,P=0.932,P=0.496),这些参数在这两种程序检查结果有显著相关性(分别为r=0.898,P＜0.01;r=0.559,P＜0.01;r=0.734,P＜0.01),并且两种检测结果有很高的一致性.检查所需时间,Humphery Matrix为3'26",FDT为5'14"(P＜0.01).结论 Humphery Matrix视野计的N-30-F程序与FDTN-30程序的检查结果高度一致,并且前者检查所需时间更短.

abstractsObjective To determine the comparability of the N-30-F test with the new Humphrey Matrix instrument to the traditional frequency-doubling technology(FDT)N-30 test.Methods A sample of 32 eyes from 32 patients(3 normal subjects,6 with ocular hypertension,10 with primary open-angle glaucoma (POAG),13 with suspect glaucoma)underwent visual field testing with standard automated perimetry,and with FDT,using the FDT N-30 program,and the Matrix N-30-F program.The plots,mean deviation(MD),pattern standard deviation(PSD),defect locations on the Total Deviation Probability(TDP)and test time were compared.Results No statistically significant differences were found between corresponding parameters of the two tests.High coefficients and the agreement were associated with the MD values,the PSD values and the total number of abnormal test locations on the TDP plot of the two tests.The test time for the Matrix test was significantly shorter.Conclusions The FDT N-30 and Matrix N-30-F tests are comparable in screening for early diagnosis of glaucoma,and the test time for the Matrix test is significantly shorter.
