Last Updated: Milestone : Scientists Partially Restore Blind Man s Vision With ’gene Therapy’
“It’s a big step for the field, neurobiologist Flannery said. Most important thing is that it is safe and permanent, he added about blind man s vision.

In a first, scientists in Europe and the US have been able to partially restore the eyesight for a blind man who suffered photoreceptor disease nearly 40 years ago. Employing the technique known as optogenetics, which involves altering cells such that they manufacture the light-sensitive proteins, scientists were able to get the vision back for the 58-year old patient. Now, he can recognize people, do the counting, locate and touch different objects.

During the tests, the patient was able to locate and touch a notebook on a table in front of him 92% of the time while wearing the goggles. Without them, he was unable to perform any visual task.

Partial sight restored in blind man
By AFP Published: May 25, 2021 08:28 PM Scientists have for the first time managed to partially restore the sight of a blind patient by altering his cells, according to the results of a groundbreaking study published on Monday.

Photo: VCGThe technique known as optogenetics, which has been developed in the field of neuroscience over the last 20 years, involves genetically altering cells so they produce more light-sensitive proteins.
In some cases of blindness, known as inherited photoreceptor diseases, light-sensing cells in the retina that use proteins to deliver visual information to the brain via the optic nerve progressively degenerate.
