Objective: For the first time, we administered reversing prism exposure to treat optic ataxia in a single patient with Balint-Holmes Syndrome (BHS), who also underwent specific trainings for simultanagnosia and ocular apraxia.
Method and results: By an introduction and withdrawal experimental design, we observed that the active treatment periods improved patient's visuospatial defects and functional autonomy.
Conclusions: We thus provided a proof of principle supporting the use of reversing prism exposure in optic ataxia within an integrated and personalized rehabilitative approach for BHS.
