Effects of Low and High Oxygen Tensions and Related Respiratory Conditions on Visual Performance: A Literature Review

摘要

Research was reviewed on the effects of hypoxia, hyperoxia, hypocapnia, and hypercapnia on a large number of visual and ocular processes. These included absolute visual sensitivity, dark adaptation, visual acuity, contrast sensitivity, depth perception, stereopsis, fields of peripheral and central vision, critical flicker/fusion frequency, color vision, afterimages, other entoptic phenomena, persistence of vision following ischemia, the standing potential, the electroretinogram, ganglion cell and optic-tract responses, visual evoked responses, ocular vessels, blood flow, intraocular pressure, intraocular oxygen, the pupil, accommodation, myopia, the crystalline lens, convergence, heterophoria, reading, other eye movements, and the cornea. Research was also reviewed on the potential toxic effects of hyperbaric oxygenation on vision.
