The effects of O_2 deprivation on the organism has been studied quite extensively by physiologists and psychologists in a low-pressure chamber or in many other methods to determine the psycho-physical changes under such conditions. The aim of this research is to study from the psychological aspects the changes of certain visual functions under low-pressure and to find their remedies. To this purpose we carried on next three fundamental experiments, which may throw some lights on further systematic studies in these fields, in the low-pressure chamber at Aeronautical Research Institute, Tokyo Imperial University. I. Visual fields: Used Forster Perimeter. We find usually in all subjects the changes of visual fields with increased altitudes and practically above the altitude of 5000m their contractions are always noted in the nasal fields and in above at greatest. In other parts of the fields their contractions are on the contrary far less than these, above all in the temporal the contraction is the slightest. When oxygen is administered at 6000m, the contraction of the visual fields return to normal in size rapidily. II. Visual acuity: Used Ishihara's Charts. Up to the altitude of 6000-6500m the visual acuity is retained actually in all subjects not any defective effects in both eyes. III. Brightness-discrimination (or contrast sensitivity): Used Masson disc. All subjects usually show a considerable diminishing of sensitivity for brightness discrimination at the altitude of 5000m and, at 6000m, a remarkable diminishing. On the same altitude, subjects report actually the darkning of visual fields and the subjective alterations of brightness as appeared in a personal experience at sea level as had gone wrong with voltage. But these impairments disappear at once by administering oxygen at the same altitude. |
