Artificial retina could restore sight to millions

Researchers at the Neurology Center of the Italian Institute of Technology have developed an artificial retinaówka, whichóra turns light entering the eye into electrical signals. These in turn stimulate retinal neuronsówki, które transmit the signal to the mózgu.

Photoreceptor degenerationóin the gridówce is one of the mainówn causes of blindness in humans. Unfortunately, there is no effective therapy for most degenerative retinal disordersówki. According to the World Health Organization based on 2010 data, there are more than 285 million in the worldóin osób affected by visual impairment.

Artificial retinaóThe eye can helpóc people suffering from intermittentóThe remarkable video of anaglyphic retinal degenerationówki often leading to blindness. The invention has been successfully tested on rats and scientists want to conduct tests on humans later this year.

– This implant could be a revolution in the treatment of blindness. We will conduct the first tests on humans in the second half of this year. We won’t have the results until 2018 – said Grazia Pertile, an ophthalmologist involved in the research.

During a study on rats poróThe sensitivity of the eye in healthy rats was testedóin the eye and in ratsóin with an artificial meshówka. Checked the so-called. pupillary reflex – The eye’s adaptation to the changing amount of light falling on the gridówka. Response of treated ratsów was almost irremovableósorrows from healthy rodents. Artificial meshówka retained its properties during a subsequent study 10 months after implantation.

GridóThe vaccine is the most important part of the eye. This is a specific membrane located inside the eyeball. Is an element thatóry receives visual stimuli and, through photoreceptors, transmits an electrical signal to the mózgu, where the image is formed, or what we see.

Artificial retinaóThe camera, developed by Italian scientistsów could revolutionize the treatment of retinal degenerationówki. The invention could contribute to the development of a new generation of biocompatible retinal prosthesesówki.
