The prevalence of optometric anomalies and symptoms in children receiving special tuition.

A case-control study was performed where 9 pupils receiving special tuition (ST-group) were compared with 36 controls. Six (66.7%) of the pupils in the ST-group were diagnosed as dyslexic. No significant correlation was revealed between receiving special tuition and having reduced visual function, nor between reduced visual function and number of visually related symptoms. Although the number of symptoms was not significantly greater in the ST-group, some of the symptoms were significantly more common in the ST-group, and none were significantly more common in the control group.
