[Follow up results and pathogenetic substantiation of the effect of decompression surgery on the optic nerve in glaucomatous optic neuropathy].
Retrospective analysis of the efficiency of optic nerve decompression in progressive glaucomatous optic neuropathy in patients with normalized intraocular pressure showed widening and/or stabilization of the visual field in remote periods (6-11 years) in 83.3% patients. Study of the hemodynamics after optic nerve decompression showed a significant improvement of the hemodynamic parameters in the orbital artery-central retinal artery system: increased bloodflow velocity in the central retinal artery, increase of ophthalmic blood pressure and perfusion pressure, dilatation of the arteries, and constriction of veins, which indicates improvement of hemoperfusion in the initial portion of the optic nerve and retina after decompression surgery on the optic nerve. Extension and stabilization of visual field correlated with positive changes in circulation.
