New artificial retina for the blind approved in Europe




20 years of research have needed specialists Second Sight Medical Products to develop this innovation. Now, after the success of mandatory safety testing, just adopted in the European market. This technology offers hope to patients with retinitis pigmentosa .

As explained by Dr. Robert Greenberg, Chairman and CEO of the company, "after years of research, we are proud to offer a real solution long term for people suffering degenerative diseases of the retina in advanced stages such as retinitis pigmentosa," noting further that this acceptance of its use in Europe represents a major step forward for the sector and for those patients who, until now, had no alternative treatment. "

The artificial retina, known as prostheses Argus II retinal , is a device previsto para tratar a personas completamente ciegas que sufren enfermedades degenerativas. El sistema convierte las imágenes obtenidas con una microcámara, insertas en unas gafas que lleve el paciente, en una serie de impulsos eléctricos enviados a través de un sistema sin cables a una matriz de electrodos colocados en la retina . Estos impulsos stimulan las células de la retina generando las correspondientes percepciones luminosas en el área de la visión, en el cerebro . De este modo consiguen recuperar cierta capacidad de visión.

La retina artificial llegará Year-end

In the words of Dr Lyndon Da Cruz of Moorfields Eye Hospital London, United Kingdom, "virtually every patient has a system stable, secure and functional to enable it to recognize large alphabetic characters, know where the objects and even to read short words. "
