The study, published in the Protocols of the Royal Society, shows that the group of German researchers has developed a retinal implant (retinal), aldehyde form of retinol, which allowed the establishment of the three blind people to see objects and determine their shape.
One blind person was even able to identify and find objects placed on a table in front of him, as well as self-pacing, closer to the people, to discern a clock face and distinguish between seven shades of gray. The device, which was developed by Retinal Implant AG together with the Institute for Ophthalmic Research at the University of Tyubingenskim is an unprecedented advances in electronic visual prostheses and could eventually revolutionize the lives of over 200,000 people worldwide who suffer from blindness as a result of the pigment retinitis (retinitis pigmentosa), a hereditary degenerative eye disease.
Disease is that the light receptors in the eye no longer function. The information in the Protocols of the Royal Society Professor Dr. Eberhart Zrenner (Eberhart Zrenner) indicate that "the results of this nalysis provide strong evidence that the visual functions of patients blinded by a hereditary retinal dystrophy can, in principle, be recovered sufficiently to their use in daily life. "
The device, known as a subretinal implant, located beneath the retina, directly replacing light receptors lost as a result of retinal degeneration. As such, it uses the natural process of creating an image the eye, the step of detecting light to contribute to the visual perception of the patient, and acts in accordance with the movements of the eye. Other types of implants known as epiretinal implants, installed outside the retina, and since they bypass the photosensitive structure intact eyes, they require the user to wear an external device and the camera processor.
The implant of the second type described in the documentary record of research, reaches unprecedented clarity, as it is more closely associated with the light receptors than other similar devices. So, Dr. Zrenner concluded as follows: "This analysis is a real proof that such devices can restore useful vision in blind people, even if the final results for a broad clinical application will require a lot more time."
