The generalized layer segmentation algorithm schematic and the construction of reference model. The segmentation algorithm was based on graph theory and dynamic programming and the segmentation of retinal layer was achieved by finding the shortest path in the limited search region. The first segmented boundaries were in pixels and the unit was converted according to the axial resolution. The foveola locations in all images were unified and the averaged boundaries were reference model
