Barton and Black indicated in a recent report that hemianopic subjects without unilateral neglect may demonstrate a horizontal line bisection bias towards the scotomatous field.1 Their study was prompted by their impression that the influence of visual field defects on spatial tasks has been little studied. The authors unfortunately seem not to have been aware of studies by Kerkhoffet al 2-4 that not only replicated Barton and Black’s findings but indicate that such findings have been recorded as long ago as 1894. It would be useful if Barton and Black could indicate whether any aspects of their study are distinguished from the preceding reports.
