Children with cerebral palsy (CP) show varying degrees of motor impairment and movement disorders whose perceptive-visual contribution has yet to be established. The literature reports that children with CP have more frequent neuro-visual disorders. The link between the location and size of the brain lesion and neurovisual symptomatology has yet to be explored.

In this retrospective clinical data study, we will investigate in children with PC whether there is an anatomo-clinical correlation between visuo-spatial disorders is the brain injury of interest to the dorsal visual pathway. We will explore the volume of grey and white matter parietal involvement.

To test visuo-spatial disorders, we will use the PVSE (Visuo-Spatial Elementary Perception) test which does not require motor skills or language and is therefore suitable for children with a PC. This test will make it possible to better identify the deficit or deficits in order to adapt an early remediation. It could serve as a reference for comparing several pathologies/etiologies.

Inclusion Criteria:

• Male or female aged 4 to 18 yo
• With a CP diagnosis
• With PVSE test completion during his/her regular follow-up
• With a cerebral MRI scan during his/her regular follow-up

Exclusion Criteria:

- With an incomplete PVSE test or whose interpretation was deemed unreliable by the rater
