Using data from the Trial of Org 10172 in Acute Stroke Treatment (TOAST), the authors studied the anatomy of gaze deviation (GD) after stroke and its co-occurrence with neglect. GD was more frequent and persistent after right hemisphere damage. GD was most common with lesions involving the frontal lobes, although rates with lesions restricted to other hemispheric regions were not significantly different. There was no difference in its rate of co-occurrence with neglect between right- and nonright-handed patients.
