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