The aim of the research was to explore structural changes changes in the central departments of the visual analyzer for glaucoma. Materials and Methods: mortem examination was carried out in two people's death was not related to diseases of the central nervous system. Far-advanced glaucoma diagnosis was established and verified in life. There have been mortem, morphological and immunohistochemical studies, including a description of the material, morphometry of the optic nerve cells, optic chiasm, lateral geniculate body and visual cortex. Results: Macroscopic examination revealed severe atrophy of the second cranial nerve with the loss of a considerable number of axons and neurons in the lateral geniculate nucleus. Micrography showed the reduction of the cell layer’s thickness of the visual cortex, the puckering of the neurons’ radius and their nuclei’s radius. Examination also revealed grumose, granular cytoplasm, the presence of lipofuscin in vast numbers, which indicates an atrophic process. In either case, neurodegeneration processes were revealed in deceased patients, who suffered from POAG. All levels of the visual analyzer’s central division were involved in the degenerative process; however, the area of the visual cortex in the area of the calcarine fissure was most noticeable. It should be highlighted that in the optic nerve and IV-V layers cortical amyloid plaques were detected and calf.
