Cogan type oculomotor apraxia
Type of disease: Rare conditions
Oculomotor apraxia Cogan type is a very rare inherited eye condition characterized by a defect in side-to-side (horizontal) eye movements. 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. To compensate for this, these infants will sharply jerk their heads past the desired object in effort to bring the eyes to a position where they can view the object. This condition can also be associated with mild developmental delay and speech difficulties. Symptoms usually improve throughout the first and second decades of life. The specific cause and inheritance pattern is unknown. Around 50 cases have been described in the medical literature.
