Overview
Visual impairment arising from the brain rather than the eye, and the leading cause of paediatric visual impairment in developed countries. The defining feature is a mismatch: the child's visual FUNCTION is worse than the ocular findings can explain. Reported prevalence is 26-83% in cerebral palsy and 21-47% in preterm infants. Critically, routine vision screening may not identify it — a normal eye examination and a passed acuity screen do not exclude CVI.
