vHIT alone cannot easily be used as a tool to decide if someone is suitable for rehab as there are many factors to consider, although it is an integral part of the test battery.
Once rehabilitation has commenced then a further application of vHIT is a tool to measure status central compensation at various points throughout the rehabilitation pathway. If rehabilitation is successful then catch up saccades should group together and reduce in latency. At this point there isn’t any recommendations of when a patient has reached their optimum state following rehab but there is a lot of researchers looking into this.
