Figure 1.
Ascent profile of both groups of climbers with indication of high camps and examination time points.
Figure 2.
Graphs describing hemorrhages in both groups of climbers at different altitudes.
Panel A: total number of hemorrhages; panel B: total area of hemorrhages; panel C: percentage of mountaineers with hemorrhages in at least 1 eye.
Figure 3.
Fundus photographs of a climber from group 1 showing the development of retinal hemorrhages during the course of her climb.
Note the white-centered hemorrhage localized at the temporal inferior branch of the retinal artery.
