Congenital oculomotor apraxia, first reported by Cogan (1952), is characterized by (1) defective or absent horizontal voluntary eye movements, and (2) defective or absent horizontal ocular attraction movements. Oculomotor apraxia occurs in ataxia-telangiectasia (208900). Also see ataxia-oculomotor apraxia syndrome (208920; 606002). Oculomotor apraxia has been observed in the neuronopathic form of Gaucher disease (type III; 231000) (Erikson and Wahlberg, 1985; Gross-Tsur et al., 1989).
