Retinal Hemorrhage at High Altitude.

Abstract

Of 20 men and women exposed to 5360 m. altitude hypoxia for periods of two to four weeks, all showed increased vascular tortuosity and dilatation and 13 showed retinal hemorrhages which were not found to cause scotomata by grid testing. Hemorrhages were asymptomatic and only weakly related to exertion, length of stay, or severity of other symptoms. These findings confirm our previous observations. (Author)
