[Pathogenesis of optic disk congestion in acute polyradiculoneuritis]

The authors analyze the development of optic disc congestion in patients with acute polyradiculoneuritis. Basing on an analysis of the brain hydrodynamics examined with the aid of the subarachnoidal infusion test, the authors come to the conclusion that the main pathogenetic factor responsible for the development of intracranial hypertension and optic disc congestion in the patients examined is the syndrome of the decreased cerebrospinal fluid absorption. It is emphasized that basic to the treatment of intracranial hypertension and optic disc edema during the disease in question should be measures aimed at the improved drainage of the cerebrospinal fluid to the cerebral venous system.
