Abstract
The corneoretinal potential is indirectly and intermittently measured. Attempts are made to evoke oscillations in the corneoretinal potential with infrared radiant energy, polychromatic light including infrared radiant energy, and with polychromatic light essentially free from infrared radiant energy. It is concluded that infrared radiant energy, as used in this study, does not contribute significantly as stimulus to evoke oscillations in the corneoretinal potential of man, when usedeither as sole source of radiant energy or together with polychromatic light. Radiant energy in form of visible light is the predominant factor in evoking both the slow and the fast oscillation. Changes in skin resistance or skin potential are not likely to contribute to oscillations observed in the corneoretinal potential when recorded by the indirect method
