Summary

In a survey of around 60000 optometric eye examinations, each with orthoptic assessment, 5% of patients were found to have a binocular vision anomaly. The frequency of each anomaly was found and an estimate was made of its prevalence in the general population. The prevalence rates are generally similar to other studies but are given in more detail. Of 3075 binocular anomalies 74% had concomitant strabismus, 10% were paretic, 8% had decompensated heterophoria and 6% convergence insufficiency.
