Retinal implant technology has improved over the last years, gaining advantages and possibilities in visual rehabilitation for patients with retinal degenerative diseases. Several study groups have already reported of succesful promotion of visual sensations by electrical stimulation of the human visual system. The Argus II epiretinal prosthesis is the first electronic device approved for partial restoration of vision in patients with retinitis pigmentosa. Nevertheless the anatomical, physiological and technical circumstances are setting boundaries for prosthetic visual restoration. We want to show our first experieces with the Argus II epiretinal prosthesis and want to rule out the possibilities and limitations of visual function by epiretinal stimulation.
