To see if there were differences in referral rates and abnormalities detected from two areas that were operating different preschool vision screening programmes.
Cohort study using case notes of referrals.
Community based secondary referral centres in the county of Avon.
263 referrals from a child population of 7105 in Southmead district, an area that used orthoptists as primary vision screeners; 111 referrals from a child population of 2977 in Weston-super-Mare, an area that used clinical medical officers for screening.
Amblyopia and squint detection rates, together with false positive referral rates.
The amblyopia detection rate in Southmead district was significantly higher than in Weston-super-Mare (11/1000 children v 5/1000), as was the detection rate of squint (11/1000 v 3/1000). However, the false positive referral rate from Southmead was significantly lower than that from Weston-super-Mare (9/1000 v 23/1000).
Preschool vision screening using orthoptists as primary screeners offers a more effective method of detecting visual abnormalities than using clinical medical officers.
观察在实施不同学龄前视力筛查项目的两个地区，转诊率和检测出的异常情况是否存在差异。
采用转诊病例记录的队列研究。
埃文郡的社区二级转诊中心。
南米德区7105名儿童中有263例转诊，该地区以视光师作为主要视力筛查人员；滨海韦斯顿2977名儿童中有111例转诊，该地区由临床医务人员进行筛查。
弱视和斜视检出率，以及假阳性转诊率。
南米德区的弱视检出率显著高于滨海韦斯顿（11/1000名儿童对5/1000），斜视检出率也是如此（11/1000对3/1000）。然而，南米德区的假阳性转诊率显著低于滨海韦斯顿（9/1000对23/1000）。
以视光师作为主要筛查人员进行学龄前视力筛查，比由临床医务人员进行筛查能更有效地检测出视觉异常。
