A “scientific revolution” .. the restoration of the “vision” of a blind Spanish woman 16 years ago

 A great scientific achievement was achieved by scientists in Spain to restore the “vision” of a blind woman, through a process described as the “scientific revolution,” during which they stimulated a brain transplant, allowing the blind woman to “see” for the first time in 16 years.

The operation allowed the patient, according to a number of medical websites and Russia Today, to see light and shapes again, using an “artificial retina” attached to a pair of glasses to direct the light in front of them.

The light processing occurred then into electrical signals.

The signals are then sent to a series of tiny electrodes implanted in the patient's brain, allowing the user to "see" the light captured by the glasses.

This system was tested on a 57-year-old woman who had not seen anything for 16 years, during which time she was completely blind.

The advanced implant enabled the woman to recognize the shapes and silhouettes that were detected by the artificial retina.

"We consistently obtained high-quality recordings from visually deprived neurons and the stimulation parameters remained stable over time," the scientists wrote in a research paper.

The patient was also able to discover “some letters” and even “recognize the boundaries of an object.”

While more research is needed before this technology can be widely deployed, the early indications are that it could be a huge step forward in fixing vision impairment and represents a breakthrough in the field.

It is reported that this is not the first time that a blind patient has been treated with a revolutionary technique to try to restore sight.

In May 2021, a partially blind man regained his sight after a form of gene therapy used pulses of light to control the activity of neurons.
