OBJECTIVE: To evaluate whether the frequency doubling perimeter (FDP) can detect different glaucomatous visual field loss. METHODS: FDP (c-20 full threshold) was performed in 93 eyes with early (n = 30), moderate (n = 37), and advanced (n = 26) glaucomatous visual field loss, and in 20 normal controls. At the same time, Humphrey Field Analyzer (HFA) test results were used as the standard. The average testing time and the correlations of mean deviation (MD), pattern standard deviation (PSD), and corrected pattern standard deviation (CPSD) were evaluated. RESULTS: The average testing time for FDP was 4.31 ± 0.47, 5.06 ± 0.49, 5.50 ± 0.63, and 4.04 ± 0.47 minutes per eye for the early, moderate, advanced, and normal groups, respectively, while the time for HFA was 16.41 ± 1.88 minutes. There was a very significant difference between the FDP group and the HFA group regarding testing time (p < 0.01). The correlation indexes between MD, PSD of FDP and MD, and CPSD of HFA were 0.86 (p < 0.01) and 0.63 (p < 0.01), 0.95 (p < 0.01) and 0.87 (p < 0.01) for the early, moderate, and advanced groups, respectively. CONCLUSIONS: FDP may help not only in the fast diagnosis of glaucoma, but also in the correct detection of early, moderate, and advanced glaucomatous visual field loss, especially when MD is used.
