Vision screening in preschool children: comparison of orthoptists and clinical medical officers as primary screeners.
OBJECTIVE
To see if there were differences in referral rates and abnormalities detected from two areas that were operating different preschool vision screening programmes.


METHODS
Cohort study using case notes of referrals.


METHODS
Community based secondary referral centres in the county of Avon.


METHODS
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.


METHODS
Amblyopia and squint detection rates, together with false positive referral rates.


RESULTS
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).


CONCLUSIONS
Preschool vision screening using orthoptists as primary screeners offers a more effective method of detecting visual abnormalities than using clinical medical officers.
