Rehabilitation for patients with homonymous visual field defects (HVFDs) is important for helping to improve their quality of life. Various therapies have been developed, most notably vision restoration training (VRT), optical aids and compensatory training. Studies utilising modem optical aids have reported promising results but the extent to which these aids can reliably reduce the patients' visual disability has yet to be confirmed. Restorative approaches are the most ambitious and controversial, aiming to restore vision to portions of the lost visual field. Whilst early studies suggested that VRT could reduce the visual field defect. recent studies using more reliable methods to monitor the patients' fixation coulc not confirm this effect.
