EnglishCerebral 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.
