Amblyopia results in physical changes to myelin

Alterations in brain connections in individuals with amblyopia, more commonly referred to as ‘lazy eye’, have been identified by a team of researchers at the University of Wisconsin-Madison (WI, USA). The research, which was published in Vision Research recently, could influence future treatments for the common disorder. Through the use of diffusion-weighted imaging, the study group were able to map three sets of pathways already known to be involved in the transfer of visual information from the eyes to the brain. Analysis indicated that water was able to diffuse more easily down the brain’s visual pathways in individuals with amblyopia...
