Actual (reported)The hypothesis is that the pressure in the retinal veins increases from chronic lack of oxygen and leads to decreased blood flow. On the basis of high altitude mountaineering this hypothesis should be verified. At the same time the adaptation capacity of the blood circulation should be analyzed, and a relationship to mountain sickness should be found.
