Abstract : In a series of experiments, the effects of intense spectral bands having the characteristics of ruby and argon laser light were measured in rhesus monkey eyes. Results obtained by measuring spectral sensitivity in their presence - or immediately after these exposures - demand a two-stage (receptor stage, neural opponent stage) explanation of spectral sensitivity for the highly light adapted eye. In continuing studies, these measures are being carried over the entire range up to intensities of laser light which will produce gross thermal injury. It is planned to relate changes in visual sensitivity to ultrastructural changes in the retina. The techniques for ultrastructural study of the vertebrate retina are briefly discussed. (Author)
