Getting closer to healing blindness

Irreversible? For science no. What’s more: you would be getting closer and closer to healing blindness. Scientists from the Dutch Institute for Neuroscience (NIN) work with the latest technology. His goal: to develop brain implants that enable vision. It is possible?

It is not an illusion, we are getting closer and closer to the healing of blindness.

Experiments on primates

There is an article entitled Shape perception via a neuroprosthesis with a high number of channels in the visual cortex of monkeys. Explain the use of high resolution implants in primates. There is something called a “phosphene”: it is the perception of a point of light in a certain place in space. These implants induced the occurrence of phosphenes in primates. With eye movements, they confirmed the position of the phosphenes induced by the scientists.

Then more complex tests would be carried out. The phosphenes were given recognizable shapes and letters. The monkeys responded successfully to these new stimuli. “Our implant interacts directly with the brain. It does not go through any earlier stages of visual processing by the eye or the optic nerve. Hence, in the future, such technology could be used to restore vision loss in blind people whose visual cortex remains intact, ”explains Xing Chen. She is a researcher for Roelfsema’s team.

The work lays the foundation for the development of a novel neuroprosthetic device with which deeply blind people can see and recognize objects again, navigate in unfamiliar environments and interact more easily in social environments, thereby significantly improving their independence and quality of life. .

Blind mice were able to regain their eyesight thanks to another state-of-the-art treatment.

Experiment on mice

Another study (Reprogramming to restore juvenile epigenetic information and recovery view) experimented on mice. Stanford University just reported that it is possible to reprogram your neurons to restore vision. Aging is a degenerative process that leads to tissue dysfunction and death. Like the optic nerves that age and damage eyesight. In this experiment, the appearance of new axons in the mice was encouraged and rejuvenated. So his vision was restored. Could this also be done with humans?

The results suggest yes. Perhaps it is true that we are getting closer and closer to healing blindness.
