Abstract
Diabetic retinopathy is the most common cause of blindness in adults in all
industrialised countries. A much better pathophysiological understanding of the
disease has been achieved during the last years. There is evidence that a
functional deficit in haemodynamics proceeds the morphological changes of the
retina. Modern technologies for measuring haemodynamic parameters and their
correlation to pathophysiology in diabetic retinopathy are discussed. In the near
future it will be possible to use these parameters as an early sign of worsening
before morphological changes occur. Measurement of the therapeutic success, e.
g., in laser coagulation would seem to be possible.
