New Study Released on Vision Restoration Therapy

Vision problems are among the most common side-effects of brain injury, and probably one of the most under-reported. Recently, researchers are making unprecedented strides in neuro-optometry:

"Columbia University Medical Center researchers have demonstrated, using functional magnetic resonance imaging (fMRI), that brain activity was increased in stroke and traumatic brain injury survivors who underwent Vision Restoration Therapy (VRT).

Researchers, led by Randolph S. Marshall, M.D., M.S., associate professor of clinical neurology and acting director, Division of Stroke and Critical Care at Columbia University College of Physicians and Surgeons, examined the fMRIs of six patients aged 35-77 with vision loss on the same side of both eyes (homonymous hemianopia) caused by stroke or traumatic brain injury. The fMRI data showed increased activity in visual processing areas of the brain as patients learned to detect stimuli in the borderzone between the seeing and non-seeing fields. This enhanced activity was identified one month after beginning treatment and suggests that the brain is responding accordingly."
