Optical coherence tomography (OCT) provides high resolution cross-sectional two dimensional retinal images, with the ability to reconstruct local retinal shape from these sections in three dimensions. OCT is capable of sampling a limited area of retina in a single image. Wider field images have become available with developing technologies including swept source (SS) OCT, as well as through the merging in series of individual B scans in two dimensions. Merging SS OCT images in three dimensions (3D) has not previously been reported. Here, overlapping SS OCT cubes were reconstructed in 3D and merged via two different methods to explore the utility and limitations of composite images for retinal shape analysis.
