Computer Game Helps Return Vision to Stroke Victims
As part of the project, researchers at the University of Rochester Eye Institute show screened images of dots and other visual artifacts to stroke victims, asking the patients to identify the shapes. Patients often say that they can see something, even if they can't tell what it is. But, when asked to guess what they're seeing, they often guess correctly. Although strokes can result in brain damage, the eyes are left intact. This means the victims just need to be taught how to process those visual signals again. That's exactly what the program does, and some patients have regained enough of their eyesight to even return to driving.
