PURPOSE: To compare the effectiveness of frequency doubling technology (FDT) in detecting abnormalities in primary open-angle glaucoma (POAG) and normal-tension glaucoma (NTG). METHODS: Twenty-nine POAG patients (29 eyes) and 27 NTG patients (27 eyes) were studied. All subjects underwent testing with program C-20 of FDT with appropriate corrective lenses. RESULTS: No significant differences were observed between the two groups in mean age, mean deviation (MD), and pattern standard deviation (PSD) measured by the Humphrey Field Analyzer (HFA). The correlation between MD values determined by HFA (x) and FDT (y) is represented by y = 0.60x - 2.7 (r = 0.78, p < 0.01) in the POAG group, and y = 0.59x + 0.6 (r = 0.81, p < 0.001) in the NTG group. although the average MD measured by FDT was significantly lower in the POAG group than in the NTG group (p < 0.05), no significant difference was found in average PSD between the two groups. In early glaucoma cases (MD
