Abstract

We present a method for assessing visual neglect using oculography, the "midpoint-fixation" task. In the test, patients showed rightward deviation of the fixation point. Pure bias in visual neglect was considered to be assessed well by this method. Newly designed stimuli that lead to stable fixation and an effective calibration procedure are proposed. The method is suggested as useful in the assessment of visual neglect.
