A feat of science, restoring the sight of a blind person
For the first time in France, the sight of a blind person has been partially restored, experts say. This technique will be a ray of hope for the blind.
According to the international website, for the first time, scientists have succeeded in partially restoring the sight of a blind patient by changing his cells.
The surgery uses a technique called opto genetics, developed over the past 20 years in the field of neuroscience, which genetically modifies cells to produce more light-sensitive proteins.
Although opto-genetics is gaining increasing popularity in the laboratory because it alters brain cells in such a way that they emit signals in response to light, animal research has shown many benefits and discoveries. But it can only be used on a limited scale on humans.
This is because high-fiber optics technology and complex surgery are needed to deliver specific light to the brain.
Scientists in Europe and the United States have selected a man who lost his sight 40 years ago after suffering from a disease called photoreceptors.
In the experiment, the 58-year-old Frenchman’s vision was partially restored and he was able to recognize, count, search and touch various objects placed on the table in front of him.
Now he can not only see the zebra crossing but also distinguish between the phone and the furniture, and it is hoped that his vision will improve over time.
