Quantifying loss of information in epiretinal devices. (A.) The retinal location of a simulated Argus II array (6×10 electrodes) and the predicted percepts generated by stimulating single electrodes both without (left) and with (right) axonal stimulation. (B) The retinal location of a simulated high-resolution array (30×50 electrodes) with analogous percepts. (C, D.) Spatial distortions result in a reduced number of effective electrodes (i.e., the number of principal components needed to explain 95% of the variance) as a function of the number of physical electrodes in the array, excluding (C.) and including (D.) axonal stimulation.
