Early vision training interventions may restore vision loss in stroke

'May' is not good enough, go back to the drawing board and come up with protocols that will lead to recovery.

Early vision training interventions may restore vision loss in stroke 

ROCHESTER - Researchers at University of Rochester have found in a new study that early vision training interventions may restore vision loss in patients of occipital strokes. A person who has a stroke that causes vision loss is often told there is nothing she can do to improve or regain the vision she has lost. New research published in the journal Brain, may offer hope to stroke patients in regaining vision.

By capitalizing on this initial preserved vision, early vision training interventions can help stroke patients recover more of their vision loss than if training is administered after six months. Also Read - Nilotinib found safe and effective for Alzheimer's disease in Clinical trial "One of our key findings, which has never been reported before, is that an occipital stroke that damages the visual cortex causes gradual degeneration of visual structures all the way back to the eyes," says Krystel Huxlin, the James V. Aquavella, MD Professor in Ophthalmology at the University of Rochester's Flaum Eye Institute. The Rochester research team--including Elizabeth Saionz, a PhD candidate in Huxlin's lab and the first author of the paper; Duje Tadin, professor and chair of the Department of Brain and Cognitive Sciences; and Michael Melnick, a postdoctoral associate in Tadin and Huxlin's labs--additionally discovered that early intervention in the form of visual training appears to stop the gradual loss of visual processing that stroke victims may experience.
