Measurement of the LCT. a MIP volumetric image reconstructed from B-scan images obtained using SD-OCT. Light-blue lines indicate the locations where the thin volumetric sections were obtained. b Thin-slab MIP image obtained at the center of the ONH (blue line indicated with arrowheads in a). c X–Y view of the thin-slab MIP image. The anterior and posterior borders of the LC were defined as the plane that best represented the margin of the hyper-reflective plate within the 200 μm wide area near the center of the Bruch’s membrane opening. The LCT was determined by measuring the distance between the anterior and posterior borders of the LC at three locations (red glyphs)
