Purpose of review 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 prevention strategies. Recent findings Clinical questionnaires are being developed and tested for reliability in an attempt to… 

Impact of Cerebral Visual Impairments on Motor Skills: Implications for Developmental Coordination Disorders

A systematic and rapid evaluation of visual function in at-risk children who have survived preterm birth or PA whether or not they have been diagnosed with cerebral palsy or DCD is proposed.

Cerebral visual impairment in children born prematurely

No visual perception test or routine ophthalmic test picked out those children identified with difficulties by the CVI questionnaire, which could be an effective means of identifying children at risk of CVI.

Is there consensus in defining childhood cerebral visual impairment? A systematic review of terminology and definitions

A systematic review of the definitions of childhood CVI in the original scientific literature to describe and critically appraise a consensual definition of the condition, arguing for the alternative definition which cannot be attributed to disorders of the anterior visual pathways or any potentially co-occurring ocular impairment.

The inter-relationships between cerebral visual impairment, autism and intellectual disability

Knowledge Assessment on Cortical Visual Impairment Among Ophthalmologists in Nepal.

Most of the ophthalmologists had a good knowledge about the cause, common risk factors, clinical features, management and prognosis of CVI, however only a limited number of participants were aware of the investigation of choice for diagnosing CVI and the leading causes of visual impairment in the developed countries.

Cerebral Visual Impairment in CDKL5 Deficiency Disorder Correlates With Developmental Achievement

The utility of a cerebral visual impairment score to better capture the range of cerebralVisual impairment severity in the CDKL5 deficiency disorder population is demonstrated and the interaction between cerebral visual impairments and developmental outcomes is elucidated.

Functional and structural connectivity of the visual system in infants with perinatal brain injury

Infants with brain injury sustained in the perinatal period showed evidence of decreased brain activity and functional connectivity during a visual task and altered structural connectivity as compared with healthy term neonates.

Site-specific abnormalities in the visual system of a mouse model of CDKL5 deficiency disorder

Cortical circuit structure and function is proposed as a critically important target for studying CDD and it is shown that the normal function of cortical circuits is dependent on CDKL5.



Assessment of cerebral visual impairment with the L94 visual perceptual battery: clinical value and correlation with MRI findings

The results suggest that children with a history of preterm birth and a clinical CP picture are most at risk for a specific PVI.

Screening for cerebral visual impairment: value of a CVI questionnaire.

This CVI questionnaire is a viable tool that has the potential of being implemented as part of a routine screening procedure for CVI, and was found to be an easy-obtainable score with a good sensitivity and specificity profile.

Babies Count: the national registry for children with visual impairments, birth to 3 years.

Assessment of Cortical Visual Impairment in Infants with Periventricular Leukomalacia: a Pilot Event-Related fMRI Study

Determining the characteristics of both the BOLD response and the ER fMRI activation may play an important role in the cortical visual assessment of infants with PVL is investigated.

Visual cortical function in very low birth weight infants without retinal or cerebral pathology.

It is suggested that premature birth in the absence of identifiable retinal or neurologic abnormalities has a significant effect on visual cortical sensitivity at 5 to 7 months' of corrected age and that gestational age is an important factor in visual development.

The Reliability of the CVI Range: A Functional Vision Assessment for Children with Cortical Visual Impairment

The purpose of the study presented here was to examine the reliability of the CVI Range.

Functional Magnetic Resonance Imaging for Imaging Neural Activity in the Human Brain: The Annual Progress

Besides formulations and basic processing methods, models and strategies of processing technology are introduced, including general linear model, nonlinear model, generative model, spatial pattern analysis, statistical analysis, correlation analysis, and multimodal combination.

Visual Impairment in Children Due to Damage to the Brain

It is announced that at this time VISUAL IMPAIRMENT in CHILDREN DUE to damage to the BRAIN PDF is available at the online library.

Defective motion processing in children with cerebral visual impairment due to periventricular white matter damage

This data indicates that visual motion processing in children with cerebral visual impairment (CVI) due to periventricular white matter damage caused by either hydrocephalus or perIVentricular leukomalacia associated with prematurity is impaired.
