Brain Reorganizes to Adjust for Loss of Vision

Posted in: Research and Developments

Atlanta (November 20, 2008) – A new study from Georgia Tech shows that when patients with macular degeneration focus on using another part of their retina to compensate for their loss of central vision, their brain seems to compensate by reorganizing its neural connections. Age related macular degeneration is the leading cause of vision loss
