Patients in UK and China regain useful vision after receiving subretinal devices from Retina Implant AG

One and a half years ago, NeuroTechZone reported on initial success of subretinal implants from the Retina Implant AG in three retinitis pigmentosa (RP) patients from Germany. The international multi-center phase of the clinical trial with the wireless implant Alpha-IMS was initiated in late 2011, involving two additional sites in Germany, two sites in London, UK and one site in Hong Kong, China. Altogether, 26 patients have received subretinal implants in the trial. The first two UK patients with RP were implanted in April 2011 and the UK doctors are recruiting additional 10 patients. The first Chinese patient was implanted on February 2012, with two more to follow. Additional sites in Hungary, Italy and the United States will soon join the trial. The data from recently implanted patients indicate a restoration of useful vision in daily life. Many of them experience visual perception in both dim and bright environments. Some patients have reported the ability to see objects 30 feet away and to read numbers on a pair of dice. Unexpectedly, one of the British patients reported having dreams in color for the first time in 25 years since becoming blind.
