Adaptive optics optical coherence tomography (AO-OCT) volume acquired over a 1° retinal region located temporal of the fovea, as illustrated by the rectangle in the funds photograph. The images on the right are en face views of particular retinal layers extracted from the AO-OCT volume. Retinal layers from top to bottom are: nerve fiber layer (NFL), ganglion cell layer (GCL), outer plexiform layer (OPL) and outer segment layer of photoreceptors (OS).
