Vision screening in New Zealand: an audit of the B4 School Check.

CONCLUSIONS: The high NPV is reassuring that very few children with visual impairment are missed by screening. The low PPV was consistent with the international literature and is related to a tendency for over-referral from the B4CS programme. Further work could evaluate increasing the threshold for referral to reduce the number of false positive cases. PMID: 30845129 [PubMed - in process]
