Cerebral visual impairment (CVI) is a visual impairment due to a heterogeneous group of disorders affecting the retro-geniculate visual pathways.

Cerebral visual impairment (CVI) is a visual impairment due to a heterogeneous group of disorders affecting the retro-geniculate visual pathways. Cerebral visual impairment (CVI) can be the result of hypoxic Ischemic Encephalopathy which occurs in 6/1000 live births in high-income countries and in 26/1000 live births in lower-income countries. CVI is often caused by perinatal complications but it can also be caused by congenital abnormalities of the brain. Impairments range in severity from blindness to children with normal acuity but disabling visual processing defects (such as object confusion or non-recognition). The diagnosis of CVI can be obtained by ophthalmological, orthoptic and neuropsychological investigations. There is a need for evidence-based assessments and interventions When should treatments and training be applied during the rehabilitation of children with CVI? Which intervention should be applied?

Because of the special needs of children with CVI and their specific characteristics, evidence is needed to provide clinicians with proper tools to obtain the diagnosis. What should be measured? Children with CVI are developing and so are their visual functions. What can we offer them to support visual development? Are there evidence-based interventions to improve their quality of life and support their daily needs, for instance at school?

This Research topic aims to highlight the needs expressed above and to recruit academics and professionals interested in continuing efforts to find more evidence-based assessment and intervention strategies to improve the outcomes and the quality of life of affected children. Subtopics of interest include:

• Visual development in children
• Diagnostic tools for measuring visual functions in disabled children
• Neuropsychological diagnosis of CVI
• Interventions for the (re)habilitation of children with CVI
• Hypoxic Ischemic Encephalopathy and visual functions
• CVI, visual field and OCT measurements
• Screening Tools for CVI (history, questionnaires)
• Educational interventions


Keywords: Cerebral visual impairment, Visual Development, Perceptual (or cognitive) visual dysfunction, Early developmental brain damage, Early intervention (rehabilitation and education)
