[Hemodynamics of the eyes in diabetes mellitus]

The authors present evidence on the state of hemodynamics of the eye in patients suffering from diabetes mellitus on the basis of rheoophthalmographic and ophthalmoscopic studies with the use of the method of fluorescent angiography of the retina. The volume circulation of the eye proved to be connected with the intraophthalmic pressure and depended on the degree of affection of the eye vessels. Its changes were two-stage in character and depended on the state of the venous outflow. Diabetic retinopathy of the II stage served as the stage during which there was a sharp reduction of compensatory possibilities of hemodynamics, and further progress of vascular disturbances were observed. Rheoophthalmography permits to assess indirectly the degree of compensation of hemodynamic disturbances and can be used to asses clinical evolution of diabetic retinopathy.
