APA Dictionary of Psychology

a condition in which a wide skull with a protrusion near the anterior fontanel (on top of the head, at the front) is associated with a beaked nose and ocular abnormalities (see craniosynostosis syndrome). The latter may include atrophy, divergent strabismus, and blindness. Neurological disorders may result from intracranial pressure, and intellectual developmental disorder may occur in some cases. Also called craniofacial dysostosis. See also Apert syndrome. [described in 1912 by Octave Crouzon (1874–1938), French neurologist]
