Figure 2: (a) Star scan modality in Heidelberg Spectralis. (b) Segmentation method in three-dimensional Slicer. The area of interest is marked in every slice on coronal sagittal and axial planes by using threshold (contrast) segmentation tool. Three-dimensional model is then generated using the internal software algorithm. (c) Multiple points are placed circumferentially of the three-dimensional -model. Every three consecutive points, curvature degree and chord length are reported. Staphyloma base is annotated as the point where curvature radius dramatically changes (arrow)
