Instruments: OCT angiography in practice - part two

I have been using the AngioVue OCT (distributed by Haag Streit UK) for over a year and would like to run through some more cases that I have encountered in practice.

Case 1

Glaucoma is a progressive condition and the OCT angiography views (Figure 1 arrows, Figure 2 blue outline) shows the wedge defect inferiorly for a patient with thin corneas and pressure fluctuations having been treated with hypotensives over an eight-year period. The loss of ganglion cells (Figure 1) can be seen to mirror the retinal nerve fibre loss and the graph shows the loss is fairly rapid. The Angioflow shows the inferior capillary loss as well as some losses nasally. The inferior nerve fibre loss gives rise to a superior visual field defect. End stage glaucoma is indicated by bayoneting of the blood vessels, atrophy of the optic disc and large pores within the lamina cribrosa indicating loss of nerve fibres.
