VRT: Computer-based training strategies have been developed to train and rehabilitate adult brain-injured patients with partial visual loss due to brain damage (Kasten et al., 1998; Sabel and Trauzettel-Klosinksi, 2005; Sabel et al., 2005). Vision restoration therapy (VRT) involves identifying and stimulating regions in the visual field that are only partly damaged by brain injury or trauma. Patients receive a customized program designed for their visual field deficits to use at home daily. Through a specific pattern of visual stimuli that gauge the user's ability to identify and react, users can gradually expand their visual fields and restore lost vision. The training can be done at home in front of a computer-based device, usually in 30-minute sessions, twice a day. During the training, hundreds of visual stimulations are presented on the monitor to the areas of residual vision. It has been proposed that repetitive stimulation of damaged visual areas leads to neuroplastic changes altering nerve activity related to vision, and strengthening synaptic interactions that can help restore some of a person's visual functions. Work by Sabel and colleagues reported findings from fifteen patients that underwent six and 12 months of VRT (Kasten et al., 2006). Visual field assessments were performed before and after VRT and then repeated an average of 46 months after completing VRT. After six months of VRT, sample stimulus detection increased significantly from about 54% to 63%. The number of undetected stimuli decreased significantly in both eyes. Continuing VRT for 12 months improved the results achieved at six months. The follow-up examination after a therapy-free interval of more than three years showed that the benefits of VRT remained stable, and vision loss did not occur in most instances. According to this study, patients with vision loss after brain injury benefit regardless of the severity of the lesion or how much of their vision is affected. Furthermore, the larger the areas of residual vision, the better the outcome with VRT. It is clear that VRT has varying results. In this study, one-third of patients studied had little or no effect from VRT, one-third had moderate but noticeable improvement, and one-third had strong or dramatic improvement. Patient compliance with VRT is reported to be very good.
