Nano Retina's Bionic Retina Seeks to Restore Sight to Persons Suffering from Retinal Degenerative Diseases

In an earier blog entry (http://jgcaesarea.blogspot.com/search/label/Nano%20Retina), I noted that I am privileged to work as a consultant for a small Israeli medical device company named Nano Retina, which is developing an ultra small bionic retina, incorporating nano-size components, designed to restore sight to those suffering from retinal degenerative diseases. Its 30-minute implant procedure requires local anesthesia, a small incision and “gluing” of the device to the damaged retina. Return of sight is anticipated to be instantaneous.

According to a recent article in The Economist entitled "Seeing into the future" (http://www.economist.com/node/17647663), a new retinal implant device, manufactured by a company named Second Sight, is soon to be granted clinical approval in Europe and will then go on sale. According to The Economist:

"The device, called the Argus II, is by no means a cure for blindness, says Robert Greenberg, the chief executive and co-founder of Second Sight, the company in Sylmar, California, that developed it. It is intended for use by people who have lost their sight as a result of retina-wasting diseases such as retinitis pigmentosa, and like the earliest cochlear implants it is designed to provide only some basic sensory assistance. But despite its limitations all 30 of the people who have received the Argus II as part of clinical trials can, at the very least, now see changes in light levels and detect objects. This means that they can navigate around obstacles, find doorways, see parked or moving cars and look at someone’s head when talking to them. A handful of them can even read large print."

Although the Argus II is a marvelous achievement, Nano Retina is "setting its sights" considerably higher. The Nano Retina device is intended to allow persons blinded by retinal disease to read, watch TV and identify faces, and the company plans initial human clinical trials within several years. Moreover, as I observed in my earlier blog, the Nano Retina bionic retina is expected to work with the natural functionalities of the eye, including pupil dilation and eyeball movement, and will be powered wirelessly by a rechargeable, battery-operated mini-laser, situated on a pair of eyeglasses.

I can personally report that since Nano Retina was established in 2009, their team of international scientists has made rapid strides toward their artificial retina target. First elements of the system are ready, and several preclinical tests have already been performed, all in accordance with a rigorous time schedule.

Truly, in my opinion, a miracle in the making . . .
