본문내용

Artificial retinal implant is a biomedical implant technology currently being developed by a number of private companies and research institutions worldwide. Artificial rentinal implant is meant to partially restore useful vision to people who have lost their sight for degenerative eye conditions such as retinitis pigmentosa (RP) and age-related macular degeneration (AMD) is a common cause of retinal blindness. In these disorders, despite a nearly total loss of photoreceptors, there is relative preservation of the inner retinal neurons. The technology consists of an array of electrodes implanted on the retina, a digital camera worn on the user`s body, and a transmitter and image processor that



Looking Forward
The feasibility of a retinal prosthesis to restore vision is currently under investigation in 5 clinical trials. The 16-electrode epiretinal implant from Second Sight Medical Products, Inc, Sylmar, California, has been implanted long-term in 6 subjects in the United States for more than 5 years, and this is the only study with subjects using the full system in their homes. Intelligent Medical Implants GmbH, Bonn, Germany, described 4 subjects with an implanted 49-electrode epiretinal array in a trial designed to last 18 months. The EPI RET3 25-electrode epiretinal array was implanted for 4 weeks in 6 blind subjects. A subretinal implant composed of a 1550-microphotodiode array and a 4x4-electrode array from Retina Implant AG, Reutlingen
