"(Medical Xpress) -- Researchers have long tried to get the optic nerve  to regenerate when injured, with some success, but no one has been able  to demonstrate recovery of vision. A team at Boston Children&amp;amp;#8217;s Hospital  reports a three-pronged intervention that  not only got optic nerve fibers to grow the full length of the visual  pathway (from retina to the visual areas of the brain), but also  restored some basic elements of vision in live mice."^^<http://www.w3.org/2001/XMLSchema#string>
