From: Quantitative evaluation of intraorbital optic nerve in optic atrophy using diffusion tensor imaging
Visualization of the average peripapillary retinal nerve fiber layer (RNFL) thickness, diffusion measures, and tract profiles of six patients with optic nerve atrophy. (A) A plot indicating the average temporal-superior-nasal-inferior-temporal RNFL thickness of optic nerve head, measured at a circle with a diameter of 3.4 mm centered on the disc by optical coherence tomography. The RNFL thickness of the atrophic eyes (solid line) was significantly reduced compared to that of contralateral non-affected eyes (dashed line). (B) Optic nerve pathway mapping by the average fractional anisotropy and radial diffusivity (\(\upmu\)m2/s) values for six atrophic optic nerves (ONs) and six non-affected ONs are presented in the left and right, respectively. (C) Average tract profiles across the ONs of six atrophic (red) eyes and six non-affected (gray) eyes plotted by mean lines with standard deviation and each node marked with dotted lines. Five nodes nearest the optic nerve head were excluded from the analysis and are shaded white in the graph.
