Unilateral spatial neglect (USN) is characterized by neglect in peripersonal and extrapersonal space, the disparity of which is unknown. We assessed these forms of neglect in a patient with USN. We promoted sight scanning in extrapersonal space and used an eye camera to measure gaze movement. We found left-sided sight scanning in peripersonal space, but right-side-biased sight scanning in extrapersonal space. Additionally, line of sight was corrected when the patient was instructed to look left in extrapersonal space and to focus the line of sight at the center. Gaze measurement thus helped to assess disparities in spatial neglect in USN.
