Fig. 3From: Measurement of corneal and limbal epithelial thickness by anterior segment optical coherence tomography and in vivo confocal microscopyBland-Altman charts showed difference in average corneal epithelial thickness measurements in relation to mean measurement between the two methods (AS-OCT minus IVCM). A positive difference showed that the values measured by AS-OCT was thicker. Bias ± 95 % limits of agreement were also displayed. No relationship was found between differences in central, superior, inferior, temporal or nasal epithelial thicknessBack to article page
