Graph showing the distribution of the distance between the peripapillary arterial circle of Zinn-Haller (ZHAC) and the merging point of the optic nerve dura mater with the posterior sclera in relation to axial length.

<p>Negative values mean location of the ZHAC between the merging point and the peripapillary ring; positive values mean ZHAC location peripheral to the merging point.</p
