Children Suffering From Cortical Visual Impairment

Brief summary

Some children present visual difficulties linked not to damage to the eye, but to damage to the brain. This type of dysfunction of the visual cerebral pathways leads, for example, to difficulties in recognition, visuomotor coordination or visuo-spatial disorders. These highly specific disorders are known as cortical visual impairment (CVI). Despite their real impact on children's development, these disorders are still poorly diagnosed in the French-speaking world. As a result, follow-up and care for these children are poorly adapted. A better understanding of neurovisual disorders and the availability of validated tools in French are therefore essential. Indeed, it is currently considered that 3 to 4% of children aged four to six, i.e. around one child per kindergarten class, have a CVI following a neuro-logical lesion acquired in the perinatal period. Because of the lack of a valid tool in French, the aim of the present study is to provide the results of a validation study of a parental questionnaire for screening children with warning signs of CVI in French. This questionnaire will be offered online using the Qualtrics tool. In order to evaluate the relevance of this questionnaire, it will be proposed, on the one hand, to parents whose child (aged 3 to 12) does not present any particular developmental difficulties, and on the other hand, to parents whose child (aged 3 to 12) seems to present signs of neurovisual disorders. By comparing their answers, the investigators hope that certain questions will reveal elements typical of neurovisual disorders/CVI, thus demonstrating the relevance of this questionnaire in facilitating diagnosis.

Inclusion criteria

* Parents of a child aged between 3 and 12 * Their mother tongue must be French, to ensure that they understand the questions asked in writing. Control group: \- Children of the parents surveyed who do not present any medical, school or family developmental particularities. Clinical group \- Children of the parents interviewed who present warning signs of CVI reported by a multidisciplinary team specialized in visual impairment.

Exclusion criteria

* no specific criteria (see inclusion criteria)
