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.

Synonym(s): ocular hypertelorismhypertelorism, ocularA 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.
