GOGGLES IMAGE (IMAGE)
Caption
The team delivered a gene that produces a light-sensing protein known as ChrimsonR into surviving retinal ganglion cells, via a single injection into the eye. The protein is then put into action with a visual stimulation system, pictured here. The user wears specialized goggles (center) with a built-in camera that sends visual information to a portable processor (upper left)—which, in turn, converts the information into patterns of light. A projector within the glasses (lower left) sends back to the eye these patterns of light, which are of specific wavelengths designed to activate ChrimsonR in the modified retinal cells. Here, the system converts the image of a hand (lower right) into a simplified pattern of light that is projected onto the retina.
