Purpose: To find applicable parameters of the frequency doubling technology perimeter (FDP), which is known to be useful in detecting early visual field loss. Methods: The subjects were 65 eyes of normal individuals, 58 eyes of glaucoma suspects, and 37 eyes of glaucoma patients. FDP (MD, PSD), SAP (MD, PSD, CPSD), and 5 parameters of OCT were analyzed. The receiver operating characteristic (ROC) curve, sensitivity, and specificity of each parameter were evaluated, and the comparison of FDP parameters by Pearson`s chi-square was made between the glaucoma suspect group and the normal group. The same comparison was made among the normal+glaucoma suspect and glaucoma group. Results: In discriminating between the normal and glaucoma suspect groups, the FDP-PSD revealed an AUC of 0.745 (cutoff: 3.17dB), which was significantly larger than that of SAP-PSD with an AUC of 0.660 (cutoff: 1.73dB). In comparing FDP, PSD by Anderson criteria was most reliable with a hit ratio of 0.732. On the other hand, in discriminating among the normal+glaucoma suspect group and glaucoma group, the SAP-PSD showed an AUC 0.971 (cutoff: 2.92dB), much larger than the FDP-PSD with an AUC of 0.863 (cutoff: 3.78dB). In addition, in comparing the parameters of FDP by Pearson chi-square, PSD 1% was the most reliable with a hit ratio of 0.813. Conclusions: FDP is a valuable screening tool in detecting early visual field loss. PSD by Anderson criteria can be a reliable parameter for the diagnosis of pre-perimetric glaucoma, and PSD 1% can be used in the discrimination of perimetric glaucoma.
