Light-deprivation and light-adaptation: a preliminary study.
Preliminary data are presented on the effect of light-deprivation on the b-wave evoked in an eye exposed to and during recovery from a 500 msec duration conditioning pulse. The data indicate that the greatest differences between the amplitude of the b-wave evoked in the normal and light-deprived eyes are found for the dark-adapted retina. If the normal and light-deprived eyes are exposed to a conditioning pulse, the differences in b-wave amplitude between them are reduced. There is an increase in the difference between the b-waves evoked in the normal and light-deprived eyes as a function of time after the offset of a conditioning pulse. Latency of the b-wave evoked in the light-deprived eyes is not longer than b-wave latency in the normal eyes.
