Abstract
Blood flow, arterial velocity, and vascular diameter were measured in patients
with retinal vessel occlusion before and after treatment, especially after light
coagulation. The mean values in the patient group showed significantly reduced
blood flow and velocity compared to the normal group. The mean group difference
before and after therapy revealed that while there is an increase in blood flow
after treatment, the normal value is not reached. Individual patient values
indicated both increased and decreased blood flow and velocity after treatment as
compared with the values before therapy. There are various stages in
microcirculatory disease and the microcirculation also behaves differently after
treatment, which could be observed by measurement in vivo of the physiological
flow parameters.
