Subacute clinical trial of a suprachoroidal-transretinal stimulation system - Clinical trial of an artificial vision system

We carried out the subacute implantation clinical trial (one month) of the STS artificial retina (9 electrodes) for two patients with advanced RP. There were no side effects such as inflammation both during the implantation and after the removal of the device. About the functional examination, both patients scored better than chance in the object detection and object discrimination tasks with head scanning. Pt 2 scored 90% better than chance in detecting the direction of motion task, but Pt 1 scored 60%, which was not significantly better than chance.
