Light-evoked expansion of subretinal space volume in the retina of the frog
B Huang and CJ Karwoski
Department of Psychology, University of Georgia, Athens 30602.
The retina of the frog was superfused with a Ringer solution containing
impermeant "probe" cations and anions. Light-evoked concentration changes
in these probe ions were measured in the subretinal space (SRS) with
ion-selective microelectrodes. A decrease in probe ion concentration was
found, and several observations suggest that this is caused by a
light-evoked expansion of the SRS. The probe ion decrease was not seen in
the isolated retina; thus, the pigment epithelial (PE) cells are important
for its generation. Pharmacological studies suggest that K+ channels in the
PE cells are important--perhaps the PE cells shrink in response to the
light-evoked decrease in SRS [K+]. The light- evoked decrease of SRS volume
may be important in the understanding of SRS solute concentrations,
retina-PE adhesivity, photoreceptor-PE cell interactions, and the
interphotoreceptor matrix.
