[Retinal vein occlusion. III. Arteriolar constriction]

The author assumes that the process of the adjustment of the disproportion between the arterial and the venous volume can be favourably influenced by a decrease in the offered arterial volume to the venous occluded blood path. This can be achieved by a narrowing of the input arteriole with the help of the method of arteriolar constriction using the argon laser. The author is of the opinion that the method of arteriolar constriction finds its application especially in the treatment of severe prognostically unfavourable forms of occlusion of the branch of the retinal vein with presence of extensive hemorrhages in the retina. In such severe forms of occlusion, the author recommends to apply the arteriolar constriction already in the early acute phase of the disease.
