[Pathogenetic mechanisms of optic nerve lesions in acute vascular optic neuropathies].
The authors analyze the findings of histomorphologic and immunomorphologic studies of 20 cadaver optic nerves from subjects with a history of acute vascular optic neuropathies due to atherosclerosis, eventuating in optic nerve atrophy: 13 atrophic optic nerves and 7 pair nerves from clinically normal eyes of the same patients were examined. The blood sera of 30 patients suffering from acute vascular optic neuropathies were tested. Noteworthy that vascular optic neuropathy associated with atherosclerosis is a bilateral process. Vascular insufficiency due to sclerotic changes in vessels of various diameters undoubtedly contributes to the pathogenesis of the optic nerve impairments in the involved and clinically healthy eyes. The developing immune status disorders and autoimmune processes also contribute to the genesis of sclerotic shifts in the vessels and optic nerve atrophy in both eyes.
