This implant manages to send rudimentary images to the brains of blind people

The Orion system allows a camera to send the information of the recorded images to an electrode implant, in the patient’s brain.

Seeking solutions against blindness still seems difficult today. However, there are many laboratories that work on this issue by exploring technology.

The vision process is complex to reproduce artificially, but in people where the visual cortex is not damaged (this usually occurs in people who are not born blind) there has been some progress. One of them rests on the work of a team of researchers from the Baylor College of Medicine, in collaboration with other entities.

It is a device called Orion, which consists of a video camera attached to glasses next to a brain implant. This is connected by electrodes to the patient to get information to the part of his brain that generates images.

Orion has been tested in six blind patients and all have been able to partially restore their vision. The system is far from perfect and is not optimized either.

The Orion device is based on the spatial distribution of images. Each point in our visual field corresponds to a part of the brain, which processes that area. The project aims to stimulate each of these parts of the brain to produce the perception of light corresponding to each point.

For now, it is in an experimental state and would still have to improve a lot to cover all the points, or a large part of them, that make up an image. But the results throw some hope.

It is not the first technology that aims to partially restore vision to blind people. A few years ago, the world’s first bionic eye, Argus II, began to be used in the United States, the result of long research.

Although the most frequent technology level to help blind people are devices that try to overcome the image barrier. Voice recognition, as well as artificial identification of objects and people, mark this path.
