Fig. 1From: Efficacies of preoperative prism adaptation test and monocular occlusion for detecting the maximum angle of deviation in intermittent exotropiaComparison of the near (30 cm) deviations by PAT and MO at the three time points. While the baseline APCT measurements did not significantly differ, the PAT deviations at 30 and 60 min were significantly larger than those by MO. Analysis used the Wilcoxon signed-rank test (**P < 0.01; n.s.: not significant)Back to article page
