[Retinal vein occlusions].
There are still gaps in understanding the etiology and pathogenesis of circulatory disorders of the central retinal vein. Although various new therapeutic approaches have been developed in the past few years, existing therapy forms are subject to controversy and available data are to some extent inconsistent. This discussion in the German-language literature is associated with varied and nonuniform terminology, which should do justice in particular to concepts of pathomechanism and degree of specificity. The general designation, "occlusion" seems to be the most suitable of all available terms since this implies no conclusions on possible etiological factors. Retinal vein occlusions develop at different sites and to varying extents. Depending on t he location of the occlusion, they can be classified into occlusions of the central vein, hemicentral vein, major branch vein, and macular branch vein. This overview provides information on the current knowledge of the pathogenesis and both established approaches and those in ongoing clinical trials for the treatment of central venous and branch vein occlusions.
