New Artificial Eye (Retina) to Give Back Sights to Blinds
Glasgow University scientists have developed an artificial retina that may give back sights to many blind people who lose their sight when the light sensitive part of the eye, the retina, is damaged.
Dr Keith Mathieson, who is leading the research, said that they are trying to make the brain fool into believing the retina is still working by implanting a microelectronic device that works in a similar way to a digital camera, into the eye.
The team is working to improve the image quality and find ways to power the chip, possibly using the same technology that lets people hear through a cochlear implant.
The light chip still depends on other layers of the retina which adapt the signals before sending them through the optic nerve to the brain. These layers remain healthy even when the eye is damaged by some of the most common causes of blindness.
