Stroke Related Vision Loss
More than 20 percent of Americans who survive a stroke or traumatic brain injury (TBI) suffer from impaired vision. Neurological vision loss can make it difficult for individuals to perform routine tasks like driving, reading and writing, which can dramatically jeopardize their confidence and independence.
The condition is called cortical blindness - this refers to blindness due to loss or injury of the visual pathways in the brain. With this condition, the vision is affected, while the eye appears to be normal.
While some limited recovery may occur within the first few weeks after a stroke, the remaining visual deficits after this initial period are permanent and until now, nothing could be done for this
