[The prognosis of arterial occlusions of the eye].

Central retinal artery occlusion is caused by embolism or changes in blood rheology and viscosity. In the past, different concepts of treatment were introduced. Main princip is to improve microcirculation by increasing the pressure of perfusion, the diameter of retinal vessels or decreasing blood viscosity. Success of therapy depends on the age of artery occlusion and the rate of persisting retinal perfusion. The different concepts of therapy and their results are discussed.
