Comparison of Diagnostic Accuracy of Heidelberg Retina Tomograph II and Heidelberg Retina Tomograph 3 to Discriminate Glaucomatous and Nonglaucomatous Eyes

VCDR from HRT 3 showed higher sensitivity than HRT II and GPS for the entire group and for those of African ancestry and of European ancestry separately. Sensitivity of MRA improved in HRT 3 with some trade-off in specificity compared with MRA of HRT II. GPS yielded erroneous classification associated to optic disk size.
