Participants were categorized into groups based on their birth date in relation to the introduction of the national vision screening programme.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>In total, the prevalence of strabismus was 1.1% (41\/3785; 95% CI: 0.8\u20131.5); no differences were found in relation to gender or screening status. The prevalence of exotropia (XT) was 0.3% (12\/3785; 95% CI: 0.2\u20130.6) and of esotropia (ET) 0.8% (29\/3785; 95% CI: 0.5\u20131.1), resulting in an XT:ET ratio of 1:2.7. A history of strabismus was present in 4.6% (174\/3785; 95% CI: 4.0\u20135.3), and a history of strabismus surgery was present in 0.8% (32\/3785; 95% CI: 0.6\u20131.2) of the participants.

The use of Hirschberg test may have led to an underestimation of the true prevalence. The prevalence was neither related to screening status nor gender.
