Changes in Angioscotomas Associated With Inhalation of Oxygen

Effect of Oxygen on Developing Retinal Vessels with Particular Reference to the Problem of Retrolental Fibroplasia

“…The extensive pertinent literature has been reviewed by Bean (1945) and will not be recapitulated here, but it is of interest to note that this effect has been demonstrated in the cerebral vessels of cats (Tinel, 1927;Wolff and Lennox, 1930;Schmidt, 1934), and that it has been observed in the retinal vessels of human adults (Rosenthal, 1939;Cusick and others, 1940;Duguet and others, 1947), and of premature babies (Lamotte, 1951;Patz and others, 1952;Huggert, 1953).…”

The Relation Between Foveal Visual Acuity and Illumination Under Reduced Oxygen Tension

“…Second, it is possible that the inhalation of 100 per cent oxygen from a cylinder may result in a slightly higher degree of visual acuity than normal air, although it is an established fact that even under the latter conditions the oxygen saturation of arterial blood is about 95 per cent of its capacity. Rosenthal (1939) has shown that inhalation of 100 per cent oxygen is associated with a contraction of the retinal angioscotomas as compared with normal air, an effect which is in the opposite direction to that caused by anoxia (Evans and McFarland, 1938). This suggests that the slight additional oxygen content of the arterial blood may produce perceptible sensory changes.…”
