Primary open-angle glaucoma (POAG) is a chronic optic neuropathy characterized by the loss of ganglion cells and the development of specific changes in the optic nerve head (ONH). Identification of structural glaucomatous changes is necessary both to verify the diagnosis and to determine the effectiveness of antihypertensive therapy. Currently there are several devices used in clinical practice that allow for an objective morphometric analysis: confocal laser scanning ophthalmoscopy (Heidelberg retinotomography, HRT), scanning laser polarimetry (SLP, GDx), optical coherence tomography (OCT) and optical coherence tomography angiography (OCTA). These devices have different examination principles and differ in their diagnostic possibilities for detecting structural changes and identifying the trends in glaucoma patients.
