Brain Implant Helps Blind Woman See

Scientists from multiple institutes of higher learning collaborated on a project to reverse blindness. Through the use of a brain implant, researchers were able to help a blind woman see and identify several letters. The six-month-long study involved a 57-year-old woman who became blind 16 years ago. The tiny implant, about the size of a penny, bypasses the optic nerve and stimulates the brain's visual cortex. The study findings appear in The Journal of Clinical Investigation.

"I would like to emphasize that although our preliminary results are very encouraging, we should be aware that this is still research and not yet a clinical treatment," said lead study author Dr. Eduardo Fernández.
