The system is designed to treat near blindness caused by retinitis pigmentosa
While the word prosthesis usually evokes images of artificial legs, arms, and these days even sophisticated thought-controlled hands, an entirely new class of replacement body part has now become a reality – the bionic eye. One of the pioneers in this field is California-based Second Sight and the company has now announced that its Argus II System has received U.S. market approval from the Food and Drug Administration (FDA).
The system is designed to treat near blindness caused by retinitis pigmentosa – a degenerative disease said to affect approximately 100,000 Americans. It consists of a tiny video camera mounted in glasses that is wirelessly linked to a receiver and microelectrode array implanted onto the patient’s retina. This microelectrode array, which spans 20 degrees of the visual field, then stimulates the remaining cells in the retina with electrical pulses that travel down the optic nerve to the brain. While it does not restore normal sight, patients can learn to interpret these signals and gain a significant increase in visual capabilities to the point where they can perceive colors, recognize large letters and locate objects.
