    Abstract:
    PURPOSE: To evaluate the reproducibility of the imo binocular random single-eye test (BRSET) and Humphrey Field Analyzer (HFA) monocular test in patients with glaucoma. STUDY DESIGN: Retrospective observational study. METHODS: We measured the visual fields (VF) of patients with glaucoma using the BRSET and HFA. All tests were repeated two months later. Mean sensitivity (MS), mean deviation (MD), sensitivity at each test location, and reliability indices were compared between the test days. Wilcoxon signed-rank test, interclass correlation coefficient (ICC), correlation coefficients, and Bland-Altman plots were generated for analysis. RESULTS: We analyzed the VFs of 46 patients with glaucoma. There were no test-retest differences for MS and MD, and ICCs were > 0.9 for MS and MD in both perimeters. Inter-test correlations for MS and MD were high. The limits of agreement (LoAs) (lower, upper limit) between test days for MS were (- 3.4, 4.0) for BRSET and (-3.3, 3.0) for HFA. The LoA for MD was (- 3.3, 3.8) for BRSET and (- 3.2, 2.9) for HFA. Sensitivity at each testing location was more variable between testing days for BRSET than for HFA. For reliability indices, LoAs between testing days were wider for BRSET than for HFA. CONCLUSION: The imo BRSET showed similar reproducibility to HFA in MS and MD. However, sensitivity at each test location varied more for BRSET than for HFA. Further studies are needed to verify the reproducibility of the imo BRSET.
