Abstract:

To determine the site or sites of adaptation in the human eye, the components of the human electroretinogram were separately analysed by the incremental threshold technique at various levels of light adaptation and in dark adaptation. The human a-wave was found to adapt over at least three log units and was still not saturated at the highest adaptation tested. To develop an inexpensive method of recording human pupillary dilation and constriction, the c-wave of the electroretinogram was investigated. An inexpensive infrared electronic pupillograph was developed for the measurement of pupillary responses. Author
