Cerebral Visual Impairment (CVI) is a visual defect caused by damage to retrochiasmatic pathways and to visual cortex and characterized by some oculomotor disorders and neurobehavioral adaptations. Methods: A sample of 66 infants with pre or perinatal brain damage diagnosed by MRI were examined in attempt to correlate visual functions and ocular motility impairments with neuroradiological findings. Results: The most of the sample (89\%) presented visual impairment while only the 59,4\% presented neurobehavioral adaptations. Psyco-visual eye movement disorders and ocular motility dysfunctions shared the same trend in children with extensive lesions. Conclusions: The extent of peritrigonal white matter reduction and of cerebral damage of cerebral damage play a role in determining the degree and quality of visual impairment. Our data suggest that the extent of lesions seen on MRI well correlates with visual findings.

Abstract

Cerebral Visual Impairment (CVI) is a visual defect caused by damage to retrochiasmatic pathways and to visual cortex and characterized by some oculomotor disorders and neurobehavioral adaptations. Methods: A sample of 66 infants with pre or perinatal brain damage diagnosed by MRI were examined in attempt to correlate visual functions and ocular motility impairments with neuroradiological findings. Results: The most of the sample (89\%) presented visual impairment while only the 59,4\% presented neurobehavioral adaptations. Psyco-visual eye movement disorders and ocular motility dysfunctions shared the same trend in children with extensive lesions. Conclusions: The extent of peritrigonal white matter reduction and of cerebral damage of cerebral damage play a role in determining the degree and quality of visual impairment. Our data suggest that the extent of lesions seen on MRI well correlates with visual findings.
