Artificial Retina

The Artificial Retina is a retinal prosthesis that can be used to treat age-related macular degeneration and inherited retinal disorders such as retinitis pigmentosa.

The device uses application-specific integrated circuits to transform digital images from a camera into electrical signals in the eye that the brain uses to create a visual image. The system features a video camera and transmitter mounted in sunglasses, a visual processing unit, and a battery pack to power the device that is worn on the belt. The retinal implant receives a signal via wireless transmission, encodes it into specific patterns of stimulation pulses that are conducted through a cable to the electrode array that stimulates the retina. The brain perceives the patterns of light spots corresponding to the stimulated electrodes.
