The effects of altitude on a series of ocular functions were studied on seven expedition members, all women aged 23-53 years, during the first ascent of the 6798-m peak Brigupanth in the Indian Himalayas. The only consistent change was a decrease in convergence amplitude. The amplitude of accommodation remained stable among the younger climbers, but decreased markedly among the older ones as higher altitudes were reached. There also appeared to be a lessened vascular reactivity to the hypoxia of altitude in the older members. Stereoscopic vision was unimpaired at all altitudes tested and extra-ocular muscle balance remained unaffected in all but two members who had an increase in their baseline phorias. Two of the summit climbers developed retinal hemorrhages. There was an average weight loss of 5.4 kg during the climb, but general health was good. Symptoms of acute mountain sickness were noted infrequently, and there were only moderate changes in the menstrual cycle.
在印度喜马拉雅山脉海拔6798米的布里古潘特峰首次攀登期间，对7名探险队员（均为年龄在23至53岁之间的女性）进行了海拔高度对一系列眼部功能影响的研究。唯一持续的变化是集合幅度减小。年轻登山者的调节幅度保持稳定，但随着海拔升高，年长登山者的调节幅度显著下降。年长队员对海拔低氧的血管反应性似乎也有所降低。在所有测试海拔高度下，立体视觉均未受损，除两名成员基线隐斜增加外，眼外肌平衡在其他所有成员中均未受影响。两名登顶登山者出现视网膜出血。攀登期间平均体重减轻5.4千克，但总体健康状况良好。急性高山病症状很少出现，月经周期仅有适度变化。
