Cerebral visual impairment in PVL typically occurs because of afferent visual pathway injury to the optic radiations, which travel adjacent to the lateral ventricles7. [5] No agencies or regulatory bodies have established protocols or guidelines for screening of at-risk populations, so each hospital or doctor generally makes decisions regarding which patients should be screened with a more sensitive MRI instead of the basic head ultrasound.
