Table 4.

False positive/false negative rates and accuracy of typical clinical 24-2 visual field (VF) metrics. Further, a measure of improvement when using best HDLM method (RNFL Probability) with associated confidence intervals.

Performance of Clinical 24-2 VF Metrics
24-2 VF Metrics	False Negatives N=57	False Positives N=45	Accuracy N=102	Difference from Best HDLM	95% CI
MD	23	7	70.5%	24.28	24.12, 24.45
PSD	14	6	80.3%	11.58	11.42, 11.75
GHT	19	2	79.4%	12.58	12.42, 12.75
CC	9	17	74.5%	16.48	16.32, 16.65
PSD or GHT	13	7	80.4%	10.58	10.42, 10.75
Any 1 of 4	6	20	74.5%	16.48	16.32, 16.65

(MD = mean deviation, PSD = pattern standard deviation, GHT = glaucoma hemifield test, CC = 5-5-1 cluster criteria).
