Figure 5: Raw optical coherence tomography angiography scan showing pulsatile blood flow in choriocapillaris and choroid in patient with high intraocular pressure (IOP). The image represents a full-thickness slab. Arrowheads indicate large choroidal vessels which become visible due to hypoperfusion of the retinal microcirculation and choriocapillaris. The IOP in this case was 38 mmHg.
