hypertelorism

 [hi″per-te´lo-rizm]
abnormally increased distance between two organs or parts.
ocular hypertelorism (orbital hypertelorism) increase in the interocular distance, often associated with cleidocranial or craniofacial dysostosis and sometimes with mental deficiency.

oc·u·lar hy·per·tel·or·ism

[MIM*145400]
increased width between the eyes due to an arrest in development of the greater wings of the sphenoid, thus fixing the orbits in the widely separated fetal position; autosomal dominant inheritance. Ocular hypertelorism is a feature of many syndromes. A distinct form [MIM*145410] shows other congenital defects such as hypospadias and esophageal anomalies.
See also: faciodigitogenital dysplasia.

ocular hypertelorism

a developmental defect involving the frontal region of the cranium, characterized by an abnormally widened bridge of the nose and increased distance between the eyes. The condition is often associated with other cranial and facial deformities and some degree of mental retardation. Also called orbital hypertelorism.

oc·u·lar hy·per·tel·or·ism

(ok'yū-lăr hī'pĕr-tel'ŏr-izm)
Increased width between the eyes due to an enlarged sphenoid bone; other congenital anomalies and mental retardation may be associated.
Synonym(s): Greig syndrome, Opitz BBB syndrome, Opitz G syndrome.

Greig syndrome - increased width between the eyes due to an enlarged sphenoid bone. Synonym(s): ocular hypertelorism

hypertelorism, ocular

A developmental, congenital anomaly in which the distance between the orbits is abnormally large resulting in a large distance between the eyes. This can be associated with mental deficiency, divergent strabismus, exophthalmos or optic atrophy. See Apert's syndrome; Crouzon's syndrome.
