High altitude retinal hemorrhage: a clinical and pathological case report.

摘要: Retinal hemorrhages may occur at high altitudes. They more commonly in association with acute mountain sickness and particularly high-altitude cerebral edema. We describe a 27-year-old man who experienced retinal as well papilledema coma 5,330-m altitude died four days later, one day after evacuation to 1,300-m altitude. At autopsy, we found the nerve fiber layer. These were sometimes distant from areas where there arterioles venules. There was perivascular red cell infiltration. Deeper layers of retina intact. conclude that form both capillaries veins speculate hypoxia, or without Valsalva effect, cause endothelial damage.
