[Features of the circulation of the fundus oculi in patients with cerebral arteriovenous aneurysms and arteriosinus anastomoses].
Hemodynamics of the fundus oculi was studied in 41 patients with arteriovenous aneurysms and arteriosinus anastomoses by fluorescent angiography. Fifty-eight fluorescent angiographic examinations of the fundus oculi were performed. The findings were compared with the clinical course of the disease and the degree of the development of the arteriovenous shunt. Analysis of the fluorescent angiograms in patients with a normal fundus oculi showed that the disorders of its hemodynamics reflect the degree of changes in the cerebral circulation in the brain vascular disease that is studied. Prolongation of the venous phase of the retinal hemodynamics is the first sign and prolongation of the arterial phase too, a later sign of changes in cerebral circulation.
