Palinopsia from posterior visual pathway lesions without visual field defects.
Palinopsia, or perseveration of a previously viewed image, may be caused by drug use or by posterior visual pathway lesions. Most cases of palinopsia due to visual pathway lesions have an associated homonymous hemianopic visual field defect. We report two patients with palinopsia caused by structural lesions of the posterior visual pathway in the absence of visual field defects. Patients with palinopsia should undergo neuroimaging even in the presence of normal visual fields.
