New research may lead to non-surgical cataract treatment

New research may lead to non-surgical cataract treatment

Washington: The University of Massachusetts Amherst recently licensed a new technology to Janssen Pharmaceuticals, Inc that holds promise of revolutionizing the treatment of cataracts and presbyopia, based on early phase discoveries by polymer physicist Murugappan Muthukumar and former graduate student Ben Mohr regarding the fundamental science of proteins in the lens of the human eye. more

After blindness, the adult brain can learn to see again

After blindness, the adult brain can learn to see again

Washington: More than 40 million people worldwide are blind, and many of them reach this condition after many years of slow and progressive retinal degeneration. The development of sophisticated prostheses or new light-responsive elements, aiming to replace the disrupted retinal function and to feed restored visual signals to the brain, has provided new hope. However, very little is known about whether the brain of blind people retains residual capacity to process restored or artificial visual inputs. more
