To date objective methods of optic nerve head (ONH) parameters examination such as optical coherence tomography (OCT) and Heidelberg retinal tomography (HRT) are of great importance. The goal of the study was to compare ONH parameters in patients with different stages of glaucoma. Analysis of obtained data showed inconsiderable difference in absolute parametric indices, this is explained by different principles of ONH borders detection (OCT - the margin of pigment epithelium layer, HRT - scleral rim) as well as subjectivity in contour detection. OCT and HRT data allow to assess glaucomatous optic neuropathy and can be used independently as well as in addition to each other. Spectral OCT provides earlier diagnosis of glaucomatous optic neuropathy compared with HRT.
