Homonymous visual field defects (HVFDs) are among the most common disorders that occur in brain damage, particularly after stroke. They lead to considerable disabilities, particularly with reading and visual exploration. A variety of different approaches, including optical aids and visual training techniques, have been examined for the rehabilitation of these HVFDs. Despite the considerable ingenuity that has been applied and anecdotal evidence that has accumulated, rigorously controlled trials that clearly establish efficacy of any method are lacking.
