| oculoencephalic angiomatosis | An incomplete autosomal dominant form of Sturge-Weber syndrome, consisting of angiomas of the choroid and meninges only. Telangiectatic angiomatosis, disseminated capillary and venous vascular malformations of the cerebral hemispheres and leptomeninges, occurring in Sturge-Weber syndrome. (05 Mar 2000) |
| oculofacial | Relating to the eyes and the face. (05 Mar 2000) |
| oculography | A method of recording eye position and movements. Origin: oculo-+ G. Graphe, a writing (05 Mar 2000) |
| oculogyria | The limits of rotation of the eyeballs. Origin: oculo-+ G. Gyros, circle (05 Mar 2000) |
| oculogyric | Pertaining to, characterised by or causing oculogyration (circular movements of the eyeballs, as in an oculogyric crisis). (18 Nov 1997) |
| oculogyric crises | Incapacitating attacks of upward eye rolling seen in encephalitis lethargica and with phenothiazine drugs. (05 Mar 2000) |
| oculomandibulodyscephaly | A syndrome of bony anomalies of the calvaria, face, and jaw, with brachygnathia, narrow curved nose, and multiple ocular defects including microphthalmia, microcornea, and cataract, often with alopecia overlying skull sutures, or alopecia areata and hypoplasia, or absence of eyebrows. The pattern of inheritance is undecided. Synonym: congenital sutural alopecia, Hallermann-Streiff syndrome, Hallermann-Streiff-Francois syndrome, mandibulo-oculofacial syndrome, oculomandibulodyscephaly, oculomandibulofacial syndrome, progeria with cataract, progeria with microphthalmia.

| oculomotor | <anatomy> Of or pertaining to the movement of the eye; applied especially to the common motor nerves (or third pair of cranial nerves) which supply many of the muscles of the orbit. The oculomotor nerve. Origin: Oculo- + motor. Source: Websters Dictionary (01 Mar 1998) |
| oculomotor muscles | Muscles of the eye that include musculi bulbi (extraocular), musculus orbicularis oculi (eyelids), and musculus orbitalis. These control the eye and surrounding structures. (12 Dec 1998) |
| oculomotor nerve | <anatomy, nerve> Responsible for motor enervation of upper eyelid muscle, extraocular muscle and pupillary muscle. Lesions of the oculomotor nerve results in ptosis (dropping eyelid), deviation of the eyeball outward, double vision and a dilated pupil. (27 Sep 1997) |
| oculomotor nerve paralysis | Partial or complete paralysis of the eye muscles due to third cranial, or oculomotor, nerve lesion. The lesion may result from injury, ischemia (cerebral haemorrhage), tumours, or other brain pathology. (12 Dec 1998) |
| oculomotor nucleus | The composite group of motor neurons innervating all of the external eye muscles except the musculus rectus lateralis and musculus obliquus superior, and including the musculus levator palpebrae superioris; the most rostral component of the nucleus is the Edinger-Westphal nucleus which innervates the musculi sphincter pupillae and ciliaris via the ciliary ganglion. The oculomotor nucleus lies in the rostral half of the midbrain, near the midline in the most ventral part of the central gray substance; fibres of the medial longitudinal fasciculus form its lateral borders. Synonym: nucleus nervi oculomotorii, nucleus of oculomotor nerve. (05 Mar 2000) |
| oculomotor response | Widespread myogenic potential evoked by visual stimuli. (05 Mar 2000) |
