Fig. 4From: A quantitative analysis method for comitant exotropia using video-oculography with alternate coverBland-Altman plot comparing the values obtained using the alternate prism cover test (APCT) and video-oculography (VOG) test. The Bland-Altman plot demonstrated consistent variability. The half-width of the 95% limit of agreement was ±5.05 prism diopters. There was no overall tendency for the values obtained using VOG to differ from those obtained using APCTBack to article page
