title: The effects of moderate doses of ethanol on heterophoria and other aspects of binocular vision.
abstract: It has been known for many years that ethanol has an impairing effect on binocular vision and the co-ordination of the ocular motor balance. Various parameters were compared before and after imbibition of a moderate dosage of ethanol. The results show an increase in esophoria (or decrease in exophoria) at 6 m, with a reduction in the negative fusional ability. They also show an increase in exophoria (or decrease in esophoria) at near, with a decrease in both the AC/A ratio and near point of convergence. There was no significant effect on the amplitude of accommodation. This study raises the possibility of an ophthalmic practitioner attempting to correct a transient, ethanol-induced ocular motor imbalance.
