Visual Behaviours (ViBes) in Cerebral Visual Impairment: Validating a Descriptive Tool to Support Diagnosis and Monitoring

British and Irish Orthoptic Journal, 2023
Introduction: Cerebral visual impairment (CVI) is the most common cause of visual impairment in children in the UK. Diagnosis is based on identification of visual behaviours (ViBes) relating to visual dysfunction.

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 ...

Coordinated optimization of visual cortical maps : 2. Numerical studies [PDF]

, 2012
In the juvenile brain, the synaptic architecture of the visual cortex remains in a state of flux for months after the natural onset of vision and the initial emergence of feature selectivity in visual cortical neurons. It is an attractive hypothesis that

Abnormal cortical development after premature birth shown by altered allometric scaling of brain growth. [PDF]

, 2006
BACKGROUND: We postulated that during ontogenesis cortical surface area and cerebral volume are related by a scaling law whose exponent gives a quantitative measure of cortical development.
