Fig. 3From: Diagnosis of posterior staphyloma using the radius of steepest curvature among retinal pigment epithelium segmentation line measured by optic coherent tomographyCorrelation of the macular curvature (MC) index with the axial length. The MC index was observed to have a strong positive correlation with the axial length (P < 0.001, r = 0.848). All eyes (178 eyes) with axial length < 26 mm were classified in the no staphyloma group, except two eyes (red dots) in the undetermined groupBack to article page
