Gene therapy success 'reverses' blindness - health - 28 April 2008 - New Scientist: "Experimental gene therapy trials have improved the vision of four people who suffer from hereditary blindness.
The preliminary results of two independent studies suggest that 'repair' genes delivered to the eye might one day cure Leber congenital amaurosis (LCA), a rare disease that strikes about 1 in 80,000 people in the UK, and 2,000 Americans in total.
Equally important, say researchers, the treatments proved safe in the six patients who received the genes – delivered by a disabled virus – via eye surgery."
