Retinal implants are developed to restore visual perception in blind patients. The retina can be stimulated from either side (epiretinal (M. Ortmanns et al., 2007) or subretinal (L. Theogarajan et al., 2006), (E. Zrenner, 2002)). With a subretinal light sensitive chip, the natural optical system of the eye is still used, allowing the patient to intuitively locate objects. The patient was 1 out of 7, who have been implanted in a clinical study in 2006 in Tuebingen, Germany (E. Zrenner et al… CONTINUE READING
