Fig. 4.

In vivo en face view of the lamina cribrosa and pores at different depth locations, (a) 56 μm, (b) 108 μm, and (c) 145 μm, from the anterior lamina surface. Eight green dotted lamina pores of (d), (e), and (f) were selected to measure lamina pore areas as well as segmented from (a), (b), (c), respectively. Video 2 (MOV, 4 MB) [URL: http://dx.doi.org/10.1117/1.JBO.17.12.126005.2] shows C-scan (en face) fly-through from anterior to posterior, reconstructed from the same volumetric scan with CCR processing.
