Visual Rehabilitation Training Alters Attentional Networks in Hemianopia: an fMRI study

Post-geniculate damage of the visual system leads to homonymous hemianopia which affects about 30% or more of all cases of stroke or brain trauma (Pambakian et al. , 1997). Hemianopia greatly reduces quality of life, affecting reading, driving and spatial navigating of patients (Das et al. , 2010). Several strategies for visual field restoration have been introduced (for review see Sabel et al. (2011)). For example, Kasten et al. (1998) showed that patients trained with light detection tasks in areas of residual vision (ARV) had significantly enlarged visual fields.
