Figure 1From: Simulation of epiretinal prostheses - Evaluation of geometrical factors affecting stimulation thresholdsSchematic representation of the various elements of the simulation framework. A schematic representation of the elements constituting the simulation framework (excluding the ground electrode) and a graphic representation of the resistivity change as a function of the retina depth. RPE is the retinal pigment epithelium, h GL is the depth at which ganglion cells are assumed to be located, h Ret is the depth where the retina ends and the RPE starts, g is the electrode-retina distance and d is the electrode disc diameter.Back to article page
