Registering OCT volumes to publicly available photoreceptor cell density data. (A) OCT scans of right (OD) and left (OS) eyes from a healthy adult control, represented as an en face projection (that is, the sum of voxel intensities in each A-scan). The coordinate space is centered on the fovea, and the center of the optic nerve is marked by a white ‘x’. The purple horizontal line indicates the B-scan in each eye which passes through the fovea (see Fig. 2). The y-axis of each pair of panels is aligned to the fovea, accounting for the slight offset between the left and right columns. (B) Sampling points from Ref.1 (described in Ref.18) which fall within the extent of the OCT. Points have been rotated and scaled to align with the fovea and optic nerve in each OCT. (C–D) Density of cone photoreceptor cells (C) and rod photoreceptor cells (D) interpolated for each A-scan position using Akima interpolation14.
