Abstract

Ocular motor apraxia has been reported in bilateral frontoparietal lesions. We report a case of ocular motor apraxia after bilateral striatal infarctions. The patient had impaired voluntary saccades and smooth pursuits in the vertical and horizontal planes with an intact vestibulo-ocular reflex. Magnetic resonance imaging showed an old left putaminal infarction and an acute infarction in the right caudoputaminal area. This case demonstrates that ocular motor apraxia may occur in bilateral basal ganglia lesions.

  Figure 1 Brain magnetic resonance imaging (MRI) of the patient. Diffusion-weighted MRI (A) shows acute infarction in right basal ganglia, and T2-weighted coronal (B) and axial (C) images show chronic infarction in the left caudo- putamen and acute infarction in the right caudo-putaminal area.
