General Discussion
Cogan type ocular motor apraxia is a rare inherited eye disorder that is present at birth (congenital). The disorder is characterized by a defect in side-to-side (horizontal) eye movements, both voluntary and responsive. When affected infants rotate their heads to the side to look at an object, their eyes will lag and then move in the opposite direction. In order to compensate for this, the infants will sharply jerk their heads past the desired object in an effort to bring the eyes to a position where they can view the object. The disorder can also be associated with mild developmental delay and speech difficulties. Symptoms of this disorder usually improve throughout the first and second decades of life. Cogan type ocular motor apraxia is a genetic condition for which the inheritance pattern has not been well established. It is not clear if it is inherited as an autosomal recessive genetic trait or an autosomal dominant genetic trait.
