AIM: To investigate the accuracy of the two diagnostic test, and to compare the clinical diagnostic value of frequency doubling technology (FDT) and optical coherence tomography. METHODS: Prospective diagnostic test was set up 83 cases (162 eyes) of glaucoma and suspect glaucoma were enrolled and examinated by OCT and FDT. To obtain studied indices by the consequences and compare and combine the two diagnostic tests. Finally, to analyze the two diagnostic tests' pre-test probability and post-test probability. RESULTS: Comparing the sensitivity and the specificity of the two diagnostic tests, the difference between them had not statistics meaning. The combined sensitivity were 88.4%, the diagnostic ability were increased 15.5% than OCT and 25.7% than FDT. The combined specificity were 84.42%, such increased 53.2% than OCT and 29.3% than FDT. OCT and FDTs pre-test probability were 39.51%, the post-test probability were 52.83% and 57.08%. CONCLUSION: OCT and FDT had better diagnostic value in diagnosing primary glaucoma, and the difference between them was not apparent. OCT and FDT combine would increase diagnostic value considerably. But in clinical application, we could not only depend on the result of OCT and FDT to determine primary glaucoma and need to detect further.LA: Chinese
