The retina is a thin layer of neural tissue that lines the back wall inside the eye. Some of these cells act to receive light, while others interpret the information and send messages to the brain through the optic nerve. This is part of the process that enables you to see. In damaged or dysfunctional retina, the photoreceptors stop working, causing blindness. By some estimates, there are more than 10 million people worldwide affected by retinal diseases that lead to loss of vision.
Until now, those who lost their vision to retinal disease would have had little hope of regaining their sight, but technological breakthroughs could soon give back the gift of sight. Several groups of scientists have already developed silicon microchips that can create artificial vision! In this article, we will examine how your retinas work and how blindness caused by retinal disease no longer means the loss of vision.
