Recent advances in cortical visual impairment [PDF]

Developmental Medicine and Child Neurology, 2001
Cortical visual impairment (CVI) is the leading cause of bilateral visual impairment in children in Western countries. This finding reflects better methods for identifying visual impairment due to CNS injury and also advances in perinatal care, which have increased the survival rate of children with neurological morbidity.

PERMANENT CORTICAL VISUAL IMPAIRMENT IN CHILDREN [PDF]

Developmental Medicine & Child Neurology, 1985
SUMMARYFifty patients with permanent cortical visual impairment were evaluated. They had a characteristic behaviour profile, usually with residual sight but poor visual attention. 30 of the 50 also had damage to the anterior visual pathway. Visual evoked potential mapping was shown to have a clear advantage over visual evoked responses, and using that ...

Cortically visually impaired children [PDF]

British Journal of Ophthalmology, 1999
Editor,—While Hoyt and Fredrick rightly state the heterogeneous aetiology of cortical visual impairment (CVI) in children,1 we were disappointed in their bland and unjustified dismissal of the value of electrophysiological studies in these cases. They fail to quote any electrophysiological studies more recent than 1979 in their review, of which there ...

Cortical visual impairment: Diagnostic criteria and treatment elements [PDF]

Specijalna Edukacija i Rehabilitacija, 2019
Cortical visual impairment is a leading cause of difficulties in visual functioning in premature children and children with cerebral palsy. Bearing in mind that a large part of the brain is involved in regulating visual-perceptive activities, the factors

Electroencephalograms of Children with Permanent Cortical Visual Impairment [PDF]

Canadian Journal of Neurological Sciences / Journal Canadien des Sciences Neurologiques, 1986
ABSTRACT:The electroencephalograms of 40 children with permanent cortical visual impairment (CVI) were studied. CVI was diagnosed in the presence of severe visual loss, normal or minimal ocular findings and clinical, electrodiagnostic and CT evidence of postgeniculate lesions involving the visual cortex. All patients had a multidisciplinary evaluation,
