ARTIFICIAL RETINA

ARTIFICIAL RETINA                                                              

ABSTRACT

In this paper I describe the need for artificial retina and the current version of artificial retina and the future expectations. For those millions of us whose vision isn't perfect, there are glasses. But for those hundreds of thousands who are blind, devices that merely assist the eyes just aren't enough. What they need are alternative routes by which the sights of the world can enter the brain and be interpreted.There are 25 million people across the globe, including 6 million Americans, who are blind or severely visually impaired by diseases such as age-related macular degeneration (AMD) and retinitis pigmentosa (RP), both of which destroy the cells that allow light to be translated into recognizable images. By 2020, that figure is expected to double, creating a virtual vision-loss epidemic.It is this current need, as well as the future threat, to create the artificial retina project.The artificial retina could help those blinded by age-related macular degeneration or retinitis pigmentosa where neural wiring from the eye to brain is intact, but the eyes lack photoreceptor activity.
