Healthy
Measurement of Retinal Venous Pressure in Chronic Low-oxygen Environment
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.

Intermittent Hypoxia
Effects of Melatonin on Sleep, Ventilatory Control and Cognition at Altitude
Low oxygen at altitude causes pauses in breathing during sleep, called central sleep apnea. Central sleep apnea causes repeated awakenings and poor sleep.
