For generations, blindness from retinal disease has been treated as an endpoint — a permanent condition to be endured rather than reversed. Now, in a convergence of cellular biology and pharmacology, scientists have grown the fragile blood vessel cells that sustain the retina from human stem cells, while a light-sensitive drug has shown early signs of restoring vision in human patients with severe retinal damage. These two advances, arriving together, suggest that medicine may be approaching a threshold where eyes long considered lost might begin to see again.
