Comparison of circumferential collagen and lamina insertion depths.

<p>Schematic of human optic nerve and peripapillary sclera cross-section, showing the location of the circumferential scleral collagen, as determined by WAXS, in relation to the typical position of the lamina cribrosa in a generic middle-aged/elderly normal human eye. % circumferential alignment is expressed as mean anisotropy, averaged over the four quadrants of eight eyes. *Distances of lamina insertion sites (average and range) are taken from the literature[<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0118648#pone.0118648.ref020" target="_blank">20</a>–<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0118648#pone.0118648.ref022" target="_blank">22</a>, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0118648#pone.0118648.ref026" target="_blank">26</a>].
