While it isn't a cure for blindness, a new experimental RNA therapy offers new hope for people who are genetically predisposed to eye-related diseases. An international team working with 11 patients suffering from a specific genetic form of childhood blindness reported that one patient regained and retained vision for more than a year after just one shot. The other 10 received the shot every three months. The work represents an exciting direction for RNA antisense therapy in addressing other genetic eye defects, researchers said.
