Drawing of the Bio-Retina implanted onto retinal tissue. The photodetectors are the small salmon rectangles on top, and the electrodes penetrate deep into the retina where they make contact with the visual neurons

Cross-sectional diagram of the retinal tissue - light is incident on the top yellow surface - striped comb-like cells are the photoreceptor rods and cones - the green cells are bipolar cells which transfer signals from the rods and cones to the blue ganglionic cells, which then connect the signals to the optic nerve (Image: Shutterstock)
At least 25-30 million people worldwide have age-related macular degeneration (AMD), one of the leading causes of blindness in middle-aged and older adults. The Israeli start-up Nano Retina has announced their new Bio-Retina, a tiny array of photodetectors which can be implanted directly on the retinal surface. Ready to enter clinical trials in 2013, the Bio-Retina restores vision to AMD sufferers almost immediately following the simple implantation process.
