Progress in rehabilitation of hemianopic visual field defects.
Visual field defects (VFDs) are common after stroke, affecting between 8 and 25% of all stroke survivors. The impact of VFDs on daily activities is significant, with poor mobility, collisions, impaired reading and driving. Up to recently, visual rehabilitation was neglected by rehabilitation specialists. Both compensatory and restitution therapies are available to improve visual function in those with VFDs. The data that support these interventions, with particular emphasis on restitution therapy, are reviewed. The possible mechanisms that underlie recovery of visual fields are explored. In summary, visual rehabilitation is available and should be considered for stroke survivors with VFDs.
