Fig. 5From: Effects of different three-dimensional electrodes on epiretinal electrical stimulation by modeling analysisThe electric field distribution in GCL of different electrode shapes with 20 μA cathodic stimuli. Left: the electric field strength at the surface of GCL; Right: the general electric field distribution in GCL shown in COMSOL. All the stimulating electrodes had the same projection of Φ = 100 μm disk to the retinal plane and an ERD of 40 μmBack to article page
