Receiver Operating Characteristic analysis. Receiver Operating Characteristic (ROC) analysis of the Structure Function Index Hemifield Test (SFI-HT), Humphrey Field Analyzer Mean Deviation (MD), pattern standard deviation (PSD) and difference between predicted and actual Heidelberg Retina Tomograph rim area. Each test was used to distinguish a group of 499 eyes from glaucoma suspects from a group of 895 eyes with glaucoma. The areas under the SFI-HT, MD, PSD, and HRT MRA curves are 0.78, 0.78, 0.80, and 0.66 respectively. The performance of the HFA Glaucoma Hemifield Test (GHT) and HRT Moorfields Classification (MFC) are also shown along with the performance of defining as abnormal any subject with either of these tests outside normal limits. Error bars represent 95% confidence intervals for sensitivity and specificity.
