    • Abstract:
      Relationship between visual functions, status of the fundus oculi, electrophysiological parameters, morphodensitometric parameters of the intraorbital part of the optic nerve, and linear bloodflow velocity (LBV) in intracranial vessels is studied in 78 patients (156 eyes) with acquired high myopia. A less than 20% decrease of LBV in intracranial vessels correlates with high visual functions. A more than 40% decrease of LBV in the anterior, median, and posterior arteries of intracranial collateral circulation correlates (r = 0.56) with the presence of central and peripheral chorioretinal dystrophy. A more than 40% decrease of LBV in the basal, vertebral, and posterior cerebral arteries of transcranial collateral circulation closely correlates (r = 0.7) with signs characteristic of partial optic nerve atrophy. The development of complications of acquired high myopia apparently depends on the deficiency of various components of collateral cerebral circulation.
