ABSTRACT
Congenital ocular motor apraxia is a rare syndrome characterized by rotational head thrusts that attempt to compensate for the lack of voluntary eye movements. We describe the clinical, oculographic and magnetic resonance imaging features of two children with congenital ocular motor apraxia.

Congenital ocular motor apraxia is characterized by impaired voluntary saccades and abnormal head thrusts to induce a fixation. We report a case of a 7-year-old boy who shows typical finding of congenital ocular motor apraxia. He had a history of spasmus nutans. His developmental milestones were delayed. Brain MRI demonstrated cerebellar vermian hypoplasia, especially in the inferior portion. We report on a case of congenital ocular motor apraxia associated with cerebellar vermian hypoplasia.

Congenital ocular motor apraxia (COA), first described by Cogan in 1953, is a rare disorder which shows characteristic defects of the horizontal voluntary saccades, and compensatory head thrust. Until now, most cases have showed a presumably congenital origin, bilaterality, and a tendency to various stages of recovery with aging. But the cause and mechanism of COA are not completely known. Occasionally, it combines with other neurologic abnormalities and metabolic diseases such as Gaucher's disease exhibit similar clinical characteristics to COA. We recently experienced a case of a 3-year-old girl who showed the clinical features of unilateral congenital ocular motor apraxia.
