In recent months, even as our attention has been focused on the coronavirus outbreak, there have been a slew of scientific breakthroughs in treating diseases that cause blindness.
Researchers at U.S.-based Editas Medicine and Ireland-based Allergan have administered CRISPR for the first time to a person with a genetic disease. This landmark treatment uses the CRISPR approach to a specific mutation in a gene linked to childhood blindness. The mutation affects the functioning of the light-sensing compartment of the eye, called the retina, and leads to loss of the light-sensing cells.
According to the World Health Organization, at least 2.2 billion people in the world have some form of visual impairment.
