Figure 2

Horizontal B-scan sections through the center of the ONH of one eye. The B-scan in the top panel was acquired after 30 min of IOP set to 10 mmHg. The B-scan in the bottom panel was acquired after 60 min of IOP set to 45 mmHg. The dashed white reference line connects the furthest point on either side of the ONH at the posterior aspect of the RPE-BM complex. The ONH surface exhibited posterior displacement relative to the reference line when IOP was elevated to 45 mmHg for 60 min (arrowhead). Changes in the shape of the peripapillary connective tissues were also consistently observed, such as posterior bowing of the RPE-BM complex immediately adjacent to the ONH (arrows).
