![]() Visual field (VF) results that show more test points outside normal limits on the pattern deviation map than on the total deviation map have been assumed to be evidence of unreliable VF results. Although there was a significant statistical correlation of FL and FN with M1, M6, and TFF, area under the curve calculations and low correlation coefficients indicate that these correlations were largely due to the sample size and have little practical significance. There was no clinically significant correlation between standard reliability metrics and GT metrics. In this study, standard reliability metrics for HFA perimetry were compared to GT metrics in a large sample of patients. Although there were no exclusion criteria for severe DISCUSSION A majority of eyes had mild visual field loss (837 eyes, 84.7%), 98 eyes (9.9%) had moderate visual field loss, and 53 eyes (5.4%) had advanced visual field loss. Patients had a mean age of 66.3 years and were largely male (93.9%), as is typical for VA-based studies. Patient characteristics, VF characteristics, and results for HFA reliability metrics are presented in Table 1. RESULTSĪ total of 988 eyes of 494 patients were included in the study. ![]() A waiver of consent was obtained to review retrospective VF data. The study protocol was approved by the Veterans Administration San Diego Medical Center (VASDMC) Institutional Review Board and adhered to the tenets of the Declaration of Helsinki. ![]()
