متن کاملCongenital ocular motor apraxia
Congenital ocular motor apraxia, described in 1952 by Professor David Cogan, is characterized by defective or absent voluntary and optically induced horizontal saccades and compensatory jerky head movements or thrusts to accomplish ocular refixation (1-3). The most common initial sign is the inability to follow objects visually. The diagnosis is usually made between the fourth and eighth months...
متن کاملCongenital ocular motor apraxia.
Nine patients with congenital ocular motor apraxia (COMA) are presented and the natural history of this condition is considered. Two presented in early infancy, before the onset of the head thrust, and the means of establishing the diagnosis at this age are discussed. All exhibited motor delay in infancy which lessened, but did not completely resolve, with time. Conceptual delay, particularly w...
متن کاملFamilial congenital ocular motor apraxia.
Congenital ocular motor apraxia (COMA) is a unique ocular motor disorder which is characterized by a deficit in initiation of voluntary horizontal eye movement with reserved reflex eye movement. Although a portion of cases with COMA were found to be associated with other abnormalities, COMA in most patients is an isolated disorder. The most characteristic appearance of these patients is compens...
