HUMAN PHENOTYPE - ANNOTATIONS

The Human Phenotype Ontology (HPO) is downloaded weekly from http://compbio.charite.de/hudson/job/hpo/lastStableBuild/artifact/ontology/release/hp.obo. The file downloaded is considered the "last stable build" available for the ontology. For more about the HPO, view their website at http://www.human-phenotype-ontology.org/.

Definition:Ocular motor apraxia is a deficiency in voluntary, horizontal, lateral, fast eye movements (saccades) with retention of slow pursuit movements. The inability to follow objects visually is often compensated by head movements. There may be decreased smooth pursuit, and cancelation of the vestibulo-ocular reflex.
Comment:Oculomotor apraxia leads defective or absent horizontal voluntary eye movements with head thrusting to look at objects to the side as well as jerky, abnormal eye movements.
Synonyms:exact_synonym: Ocular motor apraxia
 related_synonym: Defective or absent horizontal voluntary eye movements
