Cortical visual impairment in children

Current Opinion in Ophthalmology, 2012
Cortical visual impairment (CVI) is a major cause of visual loss in children worldwide. The definition of this condition is constantly evolving with respect to definition, identifying those at risk and technology for diagnosis. These advances can be used for early diagnosis, design of accommodations and services, as well as future therapies and ...

Cerebral/Cortical Visual Impairment: A Need to Reassess Current Definitions of Visual Impairment and Blindness

Seminars in Pediatric Neurology, 2019
Cerebral/cortical visual impairment (CVI) is characterized by higher order visual dysfunction caused by injury to the retrogeniculate visual pathways and brain structures which subserve visual processing. CVI has become the leading cause of significant vision loss in children in developed countries, but continues to be an under-recognized cause of ...

Behavioural Characteristics Of Children With Permanent Cortical Visual Impairment

Developmental Medicine & Child Neurology, 1987
SummaryThe common behavioral features of 50 children with permanent cortical visual impairment (CVI) are described. CVI is frequently associated with specific behavioural characteristics. The majority of these children have residual vision, but they all have variable and inconsistent visual performance, including visual acuity.

Quantitative VEP Analysis in children with cortical visual impairment

Brain Topography, 1989
Children with cortical visual impairment (CVI) usually have a typical clinical presentation. However, in some cases, it may be useful to have confirmatory evidence based on objective electrophysiologic information. To achieve this, we examined some mathematically derived parameters constructed from 20 channel visual evoked potential (VEP).

Observations on the Habilitation of Children with Cortical Visual Impairment

Journal of Visual Impairment & Blindness, 1990
There is a radical difference between the visual habilitation of children with cortical visual impairment (CVI) and those with ocular visual loss. This article presents the experiences of a developmental psychologist, a child neurologist, and a teacher of the visually impaired who worked with CVI children for a number of years.

Impaired visual cortical plasticity in schizophrenia.

Biological psychiatry, 2012
Impaired cortical plasticity may be part of the core pathophysiology of schizophrenia (SZ). Long-term potentiation is a form of neuroplasticity that has been recently demonstrated in humans by showing that repetitive visual stimulation produces lasting enhancement of visual evoked potentials (VEP).
