• The experimental device, known as the Argus II, functions to improve the vision in people blinded by retinitis pigmentosa. RP is an inherited, degenerative eye disease that causes severe vision impairment. The Argus II restores low levels of vision in functionally blind patients.
  • The device works by using a microscopic video camera, located in the glasses of the patient. The device sends collected information to a special processing unit. The unit then converts the signals to an electronic device implanted into the patient’s retina.
  • Trials were conducted on 30 subjects in 10 centers in the United States and Europe. Tests showed that 89 percent of the subjects in a trial reported that they received strong images when using the device. Further tests are continuing, based on the very promising results. The Argus II has a unit cost of around $100,000.
