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:A form of loss of vision caused by damage to the visual cortex rather than a defect in the eye.
Comment:The term cortical/cerebral visual impairment (CVI) was coined to describe damage to visual pathways and structures occurring during early perinatal development. The term cortical visual impairment was originally proposed to describe visual dysfunction in pediatric populations of non-ocular cause, and its presumed association with damage to early visual cortical areas. However, as further characterization of this condition progressed, it became evident that CVI was often associated with damage to sites beyond early visual cortex including subcortical structures, white matter pathways, as well as higher-order associative processing areas of the cortex. Thus, the word cortical has been viewed as somewhat of a misnomer, and there has been the suggestion that the term cerebral would be a more encompassing and appropriate term. Although there is still a debate in the community about the most appropriate nomenclature, the HPO will regard these terms as synonymous. It is recommended that more specific terms be used as appropriate for annotation.
