Fig. 2From: Measurement of corneal and limbal epithelial thickness by anterior segment optical coherence tomography and in vivo confocal microscopySchematic corneas displaying epithelial thickness of central, superior, inferior, temporal and nasal corneas. The figs. in each zone represented mean epithelial thickness measured by AS-OCT and IVCM and the bias (mean difference) between AS-OCT and IVCM (AS-OCT minus CM). An asterisk denoted significant difference in mean thickness reading for this epithelial zone between AS-OCT and IVCM (P <0 .05). T = temporal; N = nasalBack to article page
