In vivo 3D volumetric [3.0 (x) × 3.0 (y) × 2.9 (z) mm] OCT of the optic nerve head in the right eye of a myopic individual. Fly-through movie, in which flow (color scale representing decorrelation) was merged with structure (gray scale representing reflectance intensity), showing how the disc, retina, and choroid are perfused in a 3D volumetric fashion.
