Pixium vision, the artificial retina to render sight

Pixium, after years of work, French medical technology has proven itself in the field of artificial retina with initial clinical trials that are quite convincing at the Vision Institute.

Treatment for blindness

Behind the walls of the Center National Ophthalmology Fifteen–Vingts, hides revolutionary advances for the blind. But not just any. Only those with blindness partial, that is to say whose optic nerve is not damaged, or who are not blind from birth, get treatment here. Because first of all we have to explain thata person who has already seen, has already stimulated his brain with images, while a blinded from birth no, and therefore the brain would find it very difficult to adapt. Here are some explanations on how this marvel of technology works…

How it works

French researchers at the company Pixium Vision Directed by Bernard Gilly, accompanied by Professor José–Alain sahel, a pioneer in artificial retina, worked hard to keep the operation from happening heavier than it already is, and to make this Pixium really "simple", to avoid looking like this:

The principle seems obvious: glasses with a camera serve as an eye for the person, they transmit the data has a housing which collects the information and then transmits it at the level of the eye by infra red has a microprocessor, microprocessor that comes foothold sure the eye. Data is transmitted via electrodes located at the retina, to the optic nerve and thus to the brain. The result is still a bit weak but really concluding in the sense that a women blinded since many years arrive at to distinguish of the forms, shading of contrast.

Affordable cost?

Certainly the price of this operation is still very expensive € 100,000, but you have to know where to put the priorities, find the view, even partially must be a pure moment of happiness, especially when you’ve gone blind after a while. As Professor Sahel explains, "You have to put that in proportion to the benefit made over a lifetime".

Daredevil will be happy, he will finally be able to see what Electra looks like…
