Blind regains sight after 10 years thanks to a new technique

A 58-year-old man suffered from pigmentary retinopathy. In other words, he went blind. However, a relatively innovative new technique, called optogenetics, allowed this individual to regain his sight, more than 10 years later. He was remarkably capable of locating and touching certain objects.

In fact, this technique combines gene therapy and light stimulation. If you still can’t see the colors, you can now distinguish certain contrasts. Now he trains at the Center hospitalier national d’Ophtalmologie des Quinze-Vingts, in the heart of the French capital, to detect and catch certain objects.

The blind recover their sight thanks to optogenetics

A big step forward for this individual who, a victim of a degenerative retinal disease, had mourned the loss of sight. Doctors injected a protein, ChrimsonR, which then allowed it to detect the light. Five months after the injection, the researchers let the body work, work, and produce this protein. Equipped with specific glasses, the man was able to regain certain sensations, approximately seven months later.

Shapes and objects, now visible

At this point, Alain can see the crosswalks and his kitchen. There is still a lot of work to do to help the body regain all its sensations. However, the first results are more than encouraging. Therefore, the benefits of optogenetics seem to be confirmed, enough to consider further studies, investigations and analyzes, even more extensive.
