Bilateral cortical visual impairment resulting in Anton's syndrome

Clinical and Experimental Optometry, 2020
Anton's syndrome is a form of total cortical blindness where the patient is objectively blind but denies having vision loss.2009 The denial of vision loss is termed visual anosognosia.2014 In addit...

Cortical Visual Impairment Secondary to Hypoglycemia

Neuro-Ophthalmology, 2005
Cortical visual impairment (CVI) most commonly occurs in children after hypoxic insults but may also occur as a sequel of meningitis, encephalitis, head trauma, and hydrocephalus. CVI secondary to hypoglycemia is rarely encountered. A 4-year-old girl was admitted to hospital with a history of bilateral visual impairment.

Cortical visual impairment in children with infantile spasms

Journal of American Association for Pediatric Ophthalmology and Strabismus, 2000
Infantile spasms are often associated with cortical visual impairment.We report a series of 10 patients with infantile spasms, hypsarrhythmic electroencephalograms, and developmental delay, (ie, West syndrome), who presented with severe visual inattention despite a normal ocular examination.At follow-up (14 months to 6 years), 5 patients (50%) had no ...

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 ...

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).

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 ...

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).
