Retinal Implants
Retinal institute technology is improving rapidly. Just a few years ago there was no treatment or any(prenominal) implant that could restore some or any potbelly to the blind or people with degenerative diseases such as Retinitis Pigmentosa. As of now there argon only 2 forms of implants. The first is a caller-out called Second Sight in Sylmar, California.They developed a retinal implant called argus II. Argus II is a video camera mounted on eyeglasses that captures images. These images are converted into electrical signals by a processor and sent wirelessly to a receiver implanted in the eye. The receiver sends the data thru a cable to an array of electrodes that throb with electricity that activate cells in the retina. The cells in the retina send signals thru the eye gist to the brainpower which are interpreted by the brain as patterns and low resolution images. The Second is a company called Retinal Implants AG. There implant is a micro impediment that is 9 square mm and is implanted directly beneath the retina. The chip contains 1500 electrodes that are powered inductively by transmitter coils placed at a lower place the skin.
Light enters the eye hits the electrodes and is converted into electricity which stimulates the nerves in the retina. The nerves then send the signal thru the optical nerve to the brain which produces sight allowing people to see shapes and even read. These technologies are similar and improving rapidly, the future for blind or partly blind people looks promising.
