The authors evaluated the correlation between differential light threshold test and frequency doubling technology (FDT), a new perimeter using frequency doubling illusion. The tests were performed on 68 eyes of 68 glaucoma patients and 23 eyes of 23 normal persons. All eyes were examined by 24-2 program of Humphrey Field Analyzer (HFA) and C-20 program of FDT. Average testing time were 669 sec for HFA and 277 sec for FDT. The mean deviation and pattern standard deviation were significantly correlated between HFA and FDT (r= 0.79, 0.86). The correlation of retinal sensitivity by the two tests was better in the peripheral than in central areas. Sensitivity of 97.1% and specificity of 95.7% were obtained using FDT. The findings show a good correlation between FDT and differential light threshold test. LA: Japanese
