Figure 1. Cutting the optic nerve head trephine in the orientation of the acquired B-scan.

Figure 1

A – The SD-OCT IR image including the 15°-acquisition box, viewed at 50% opacity, has been aligned to an image of the optic nerve head trephine.

B – The coordinates of the acquisition box have been burnt onto the trephine image

C – Cuts have been made in the trephine, in an attempt to get the closest approximation to the orientation of the acquired B-scans. The cut made in the superior part of the trephine (red arrows) most closely matches the acquired B-scan orientation. The trephine was embedded with the superior cut surface facing downwards.
