An automated and objective cover test to measure heterophoria

Agreement between CT, TH and ET methods.
(a) Heterophoria measurements obtained with the CT, TH and ET methods. CT and TH results are averaged across participants and ET results are averaged across sessions and participants. (b) Magnitude (absolute value) of heterophoria measurements obtained with the CT, TH and ET methods, averaged across participants for the CT and TH, and across sessions and participants for the ET. Circles are means and error bars represent 95% within-subject bootstrapped confidence intervals of the mean. * p<0.05; *** p<0.001.
