In a large population of children in Scotland aged 3.5-5.5 years, the prevalence of BVAnom is increasing, especially exotropia. Many cases of BVAnom would not be detected by solely assessing presenting vision, highlighting the benefits of including binocular vision tests in vision screening. It is recommended that vision screening is repeated during the school years.
