Artificial retina imaging has made great improvements in the last decade, and is poised to make an even larger advancement in the near future. In the future those with retina damage caused by retinitis pigmentation could once again see in 20/20.. When a person has lost their sight to a damaged retina there is now technology that allows them to see again. By means of a chip which sends electrical signals to the optic nerve. They then have their sight partially restored.. Monday, April 18. Mike Vue. Artificial Retina allows someone who has lost their vision to see again. The technology is implanted in the eye and it sends signals to allow the person to see.. Table of contents. Figure 15.1 The eye and accessory structures.
