Scientists have used the gene-editing technique CRISPR in an attempt to restore vision in a patient with a type of inherited blindness, researchers announced last week.
The experimental treatment is meant to snip out a genetic mutation that causes severe visual impairment, often starting at birth. It also marks the first time doctors have used CRISPR directly inside a person’s body. In a few weeks, they hope to know whether the treatment is working. If it works and is safe, it opens up the possibility of using CRISPR against many more conditions.
