[Retinal hemodynamics in cerebrovascular accidents]

In 32 patients the times of retinal passage were determined in 112 examinations immediately after cerebrovascular insult and following in daily intervals. In this case after the insult a significant change of the retinal haemodynamics could be observed: the bolus-tension time and the time V2 showed a continuous deterioration of the blood supply of the retina possibly parallel to the cerebral haemodynamics. Furthermore it was shown that the initial prolongation of the arm-retina-times over 17 seconds refers to serve cerebral lesions with poor prognosis. It seems that the method described is not suitable for the preliminary diagnosis of extracranial vascular processes: In acute extracranial vascular occlusion we found equality of the sides of the inflow of dye as well as differences of the sides of more than 30 seconds in free extracranial vascular lumina.
