Prevalence of general dysfunctions in binocular vision
A 1-year clinical trial to determine the prevalence of general dysfunctions in binocular vision in a nonpresbyopic population was conducted in 1679 subjects aged 18 to 38 years. A thorough eye examination included binocular vision testing. A high prevalence of binocular vision dysfunctions was found. Of the subjects, 56.2% presented symptoms of binocular dysfunctions, 61.4% with accommodation disorders and 38.6% vergence disorders. Accommodation insufficiency was most prevalent among those with symptoms (11.4%).
