Based on a retrospective analysis that was performed with data of 69 patients who had been interviewed after six months of VRT, results from the study identified that neurologically induced visual field deficits have been shown to improve by 5 degrees of visual angle with VRT. VRT significantly increased detection ability and most patients (88%) reported subjective benefits in activities of daily living (ADL). Visual field size improvements did not correlate significantly with “visual confidence/mobility” and “ability to avoid collision.” Thus, visual field size appears only to be one factor among others determining subjective vision in brain-damaged patients.

Patients reported subjective benefits including walking/mobility, confidence/independence, reading, hobbies/watching TV.
