Live Demonstration: A Wearable Device for Optogenetic Vision Restoration

Optogenetics therapy aims at recovering visual function in patients suffering from retinal degeneration and blindness. An external device is generally required to correctly encode light stimulation into neural electric activity and properly accomplish visual restoration. In this demo, we present photostimulation glasses for adequately activate optogenetically-treated retinal ganglion cells (RGC). This device performs light transduction at appropriate wavelength and intensity for an optogenetic therapy, and performs the visual computation in place of the degenerated retinal layers. We show the possible configurations and stimulation modes to be used for clinical trials or rehabilitation purposes.
