Figure 3

Optical coherence tomography images of RNFL thickness measurement. (a) RNFL thickness was measured on a circle (black circle) with a diameter of 3.45 mm centered on the optic disc. (b) RNFL thickness was measured on the b-scan image in the black circle in (a) and compared with the standard database. The ranges of normal, borderline, and outside normal values are represented in green, yellow, and red colors, respectively. (c) Quadrant division and corresponding RNFL thickness (the average RNFL thickness was 102 μm). T temporal, S superior, N nasal, I inferior, RNFL retinal nerve fiber layer.
