The Food and Drug Administration has offered new hope for the blind with the approval of an artificial retina.
Will this eventually be akin to the cochlear implant for the deaf?
The artificial retina is a sheet of electrodes implanted in the eye. The patient is also given glasses with an attached camera and a portable video processor. This system, called Argus II, allows visual signals to bypass the damaged portion of the retina and be transmitted to the brain.
