Optic disc imaging findings. Red-free fundus photographs of the right eye (top left) and left eye (bottom left) highlight the white frayed appearance of the peripapillary myelinated retinal nerve fibers. Each green box outlines the sample area of the corresponding optical coherence tomography (OCT) imaging, which is centered on the optic discs. False color OCT B-scans of the optic nerve head in the right eye (top middle) and left eye (bottom middle) reveal a substantially thickened retinal nerve fiber layer. En face OCT angiogram images of the right eye (top right) and left eye (bottom right) provide detailed visualization of the dense vascular network surrounding each disc.
