Retinal visual prostheses (“bionic eyes”) have the potential to restore vision to blind or profoundly vision-impaired patients. The medical bionic technology used to design, manufacture and implant such prostheses is still in its relative infancy, with various technologies and surgical approaches being evaluated. We hypothesised that a suprachoroidal implant location (between the sclera and choroid of the eye) would provide significant surgical and safety benefits for patients, allowing them to maintain preoperative residual vision as well as gaining prosthetic vision input from the device. This report details the first-in-human Phase 1 trial to investigate the use of retinal implants in the suprachoroidal space in three human subjects with end-stage retinitis pigmentosa. The success of the suprachoroidal surgical approach and its associated safety benefits, coupled with twelve-month post-operative efficacy data, holds promise for the field of vision restoration.Trial RegistrationClinicaltrials.gov NCT01603576

Welcome to Las Vegas and the 29th IEEE Conference on Computer Vision and Pattern Recognition (CVPR). In addition to the main four day program of presentations, interactive sessions, plenary talks, demos, exhibitions, and social functions, CVPR 2016 has a number of colocated events, including 29 workshops and 22 tutorials. As the field of artificial intelligence has become a major player in the technology world, this year's CVPR has made history in a number of exciting ways.

Participants successfully completed vision tasks using a 20 electrode suprachoroidal retinal prosthesis. Vision processing with a Nyquist bandlimited image filter has shown an advantage for a light localization task. This result suggests that this and targeted, more advanced vision processing schemes may become important components of retinal prostheses to enhance performance.
