" Through Optogenetic therapies able to restore vision to those who blind impaired"
Researchers have found that optogenetic treatment, which is a precursor to an attempt to restore the vision of the visually impaired, can improve the ability of the visually impaired to identify objects.
This optogenetic treatment is considered to be a pioneer in the medical field, as a result of the success of the experiment in which a blind man can regain some of his vision after undergoing gene therapy that uses light detection to control the function of nerve cells.
Doctors are happy to say that the 58-year-old ophthalmologist from Brittany in northern France is now able to see, count and find.
Researchers believe that this is possible because light, which involves the transformation of nerve cells (neurons), receives electrical signals when exposed to certain wavelengths.
Rare, genetic disorders involving the loss of retinal light-sensitive cells affect more than 2 million people worldwide and cause complete blindness.
As a result, retinal cells are inserted into specific eye cells, which are modified to carry light-responsive algae protein into the eye.
Thus, the scene is sent as information to the brain when the damaged retinal cells are bypassed and the modified cells sense light.
As a result, light is transmitted to the patient's eyes using glasses that capture images of objects at a specific wavelength and transfer them to the cells of the eye, thus enabling the human to see.
Used for this treatment, it will take time for the eye cells to begin producing protein and the brain to adapt to the new structure, the researchers said.
It is noteworthy that the result of this treatment is that although it is not possible to get full vision, it is comforting to be able to detect objects with partial vision, and if this treatment is improved, it will be possible to get full vision in the future, the researchers said.
