Photoreceptoral basis for altered dark-adaptation in retinal degeneration (RCS) rats.
The 'fast PIII' rod mediated photoreceptor response to flashes of monochromatic light has been investigated in isolated retinae of the RCS rat at age 30 days. A loss of both sensitivity and maximum response amplitude were found, with a concurrent slowing of the response kinetics. These observations indicate a rod abnormality which may underly the altered adaptational properties in these retinae.
