American scientists have achieved revolutionary results that open hope to restoring sight to millions of people with congenital blindness, using the gene-editing technology “CRISPR”.
According to the Spanish newspaper, El Confidencial, the technique provided new results to restore sight to many blind people, due to a genetic disease called “Liber”.
“This is the first time they have concrete evidence that gene-editing technology works efficiently in the body and improves visual function in blind people,” said Eric Pearce, professor of ophthalmology at Harvard University and the Massachusetts Eye Institute.
Instead of extracting cells from subjects’ bodies — to edit their genes and then reinjecting them — the researchers modified a virus using CRISPR technology, ramping up their numbers billions of times to get the doses needed.
And the American public radio NPR said, “Scientists have injected different doses of these viruses into the retina of 7 patients with this genetic disease.”
The radio indicated that “the virus, upon injection, began to infect the cells of the retina, but instead of producing copies of it, the virus modified the genetic mutation that causes the disease, restore vision, and reactivate dormant cells.”
