Retinitis pigmentosa (RP) is a rare genetic disorder that sabotages the retina's ability to respond to light by disabling rod photoreceptors. The National Eye Institute estimates that one in 4,000 people around the world suffer from the disorder. In the UK however, people who have lost their sight to RP may soon have hope as the National Health Service (NHS) funds the implantation of a device among ten patients to help treat this form of blindness. The Argus II Bionic Eye implant works in tandem with a small camera mounted on a pair of glasses that is worn by the patient. Images from the camera are converted into wireless signals via electrodes attached to the retina.
