20 patients (age: 68 +/- 9 years) with an acute central artery obstruction of the retina were examined in a prospective study. All patients received a hyper- or isovolemic hemodilution depending on the haematocrit value for a period of 10 days. Clinical, hemodynamical and rheological data of these patients were recorded before therapy, after 10 days and after 6 weeks. Under this therapy, 10 patients presented an improved central vision by 2 or more stages. The degree of the distributed circulation can be determined by means of the arteriovenous passage time (AVP) and the dye bolus velocity (MDV). Compared to a control group, a significantly increased arterious-venous passage time and decreased dye bolus velocity can be observed initially. The values after 10 days of therapy and after 6 weeks were significantly improved (p less than 0.01) compared to the initial values.
