Figure 2A: HRT and GDx printout A: HRT printout. Top left shows the reflective image of the patient ONH. Next, the vertical topographic profile of the ONH. Top right shows the graphical representation of the MRA. The mid pictures represents the horizontal topographic profile of the ONH and RNFL thickness respectively. Bottom left table shows the stereometric parameters (patient’s values, changes from baseline exam, and normal ranges). Bottom right picture represent the MRA with 95% confidence intervals.
