Doctors were first able to partially return vision to a person after 40 years of blindness


With the help of gene therapy, the research group partially restored vision at a blind man.

The 58th anniversary of the Frenchman lost sight of 40 years ago due to a pigment retinit, a hereditary disease, which causes the degradation of photosensitive cell cells. It became the first patient who informed the improvement after applying the method of opthenetic therapy.

The international group of scientists was able to achieve this in the eye of a man’s cold virus with a modified genetic code, which made the upper layer of ganglion cells (transmitting visual signals to the brain) sensitive to amber light. After 5 months of transformation in the retina, the doctors gave it special glasses that project the image on the retina in the desired range.

Since the ganglion cells sent unusual signals to the brain, it took him some time to learn to perceive them and interpret. After seven months of training, a man was able to distinguish such objects like a notepad, a small box for brackets, a glass cup and a strip on a pedestrian crossing.

According to scientists, the current level of therapy does not yet allow to provide a high level of perception detail, sufficient to read books or face recognition, but can significantly improve the lives of blind people.

At the end of last year, the team from the University of Monasha also reported on the implantation of the first
