Washington: Scientists claim to have developed an `artificial retina` which could restore near-normal vision to the blind, a finding which can benefit millions. Researchers made the blind mice see clearly with radical new implant and the creatures` vision could track images and discern features. This new approach provides hope for the 25 million people worldwide who suffer from blindness due to diseases of the retina. The researchers say they have also cracked the code for a monkey retina, which is essentially identical to that of a human and hope to quickly design and test a device that blind humans can use. As drug therapies help only a small fraction of this population, prosthetic devices are their best option for future sight. "This is the first prosthetic that has the potential to provide normal or near-normal vision because it incorporates the code," Dr Sheila Nirenberg, neuroscientist from Weill Cornell Medical College in New York ,said.
