Flicker perimetry was performed using the Octopus 311 and its remote software package. Suprathreshold four\u2010zone probability strategy was used to classify the critical fusion frequency probability level. The classified levels were set at 5% and 1% of probability of normality and 5\u2003Hz. Frequency doubling technology perimetry was performed using 24\u20102\u20105, 24\u20102\u20101, N\u201030\u20135, N\u201030\u20131 screening programs using Humphrey Matrix perimetry. Standard automated perimetry was performed using the Humphrey field analyser program 24\u20132 full threshold. Optical coherence tomography using Stratus OCT was used for evaluating the retinal nerve fibre layer thickness in all glaucoma and glaucoma suspect patients.<\/jats:bold> <\/jats:p><jats:p><jats:bold>Results:\u2002<\/jats:bold>  <jats:bold>Receiver operating characteristic (ROC) curves were calculated. In the early stage of glaucoma, the areas under the ROC curve (AUCs) were 0.96 in flicker and 0.90 in Matrix perimetry. In the moderate and advanced stages of glaucoma, the AUCs were almost 1.0 in all tests. In glaucoma suspect patients, the AUC of the 5% probability level in flicker was significantly higher than in Matrix perimetry.<\/jats:bold> <\/jats:p><jats:p><jats:bold>Conclusion:\u2002<\/jats:bold>
