Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are parents of children aged 3 to 12 who are French speakers and have concerns about their child's visual development.
✕Probably not a fit
Patients who do not have children within the specified age range or who do not speak French may not benefit from this study.

What this trial studies
This study aims to validate a questionnaire designed to screen children for cortical visual impairment (CVI), a condition where visual difficulties arise from brain damage rather than eye damage. The research focuses on children aged 3 to 12, particularly those whose parents are French speakers, to ensure accurate understanding of the questionnaire. By identifying children with CVI, the study seeks to improve diagnosis and care for this often-overlooked condition, which affects a significant percentage of young children. The study will involve both a clinical group of children showing signs of CVI and a control group without developmental issues.
Why it matters
Potential benefit: If successful, this study could lead to improved diagnosis and tailored interventions for children suffering from cortical visual impairment.
How similar studies have gone: While there is limited information on similar studies, the validation of screening tools for specific conditions like CVI is a recognized need, suggesting potential for success.
