Whole cell patch-clamp recordings were performed on freshly dissociated rat retinal ganglion cells to determine the action of Angiotensin II (AngII) on voltage-activated calcium current subtypes in this cell type. AngII had no effect on a toxin-resistant calcium current component; N-type currents were reduced by 27 +/- 5% in all retinal ganglion cells (RGCs) tested; L-type currents were reduced by 33 +/- 7% in 59% of the RGCs but increased by 31 +/- 6% in 41% of the cells. AngII effects were reversible within a few seconds through reperfusion with bath solution and calcium current kinetics and current-voltage relations remained unaffected. The net effect of AngII in a single RGC is either a reduction or an enhancement of the total calcium current, dependent on (1) the number of L-type channels compared to N-type channels and (2) on the kind of action AngII exerts on L-type channels.
