An estimated 295 million people suffer from visual impairment globally. Around 43 million of those people are living with blindness. While not every form of blindness can be cured, recent scientific breakthroughs have uncovered new ways to treat some forms of inherited blindness through gene therapy.
Jean Bennett is a gene therapy expert and a professor emeritus of ophthalmology at the University of Pennsylvania. She and her laboratory developed the first gene therapy drug for a genetic disease to be approved in the U.S. The drug, Luxturna, treats patients with biallelic RPE65 mutation-associated retinal dystrophy, a rare genetic disorder that causes visual impairments and blindness in patients early in life.
