Images of the acquisition in the left eyes of a healthy subject (a) and a glaucoma patient (b) using the optical nerve head rim analysis possible with Spectralis’s optical coherence tomography Glaucoma Module Premium Edition. The new software performs 24 high-resolution 15° radial scans (green lines in the upper left infrared image). In the upper right B-scan image of each figure, minimum rim width (MRW) (blue arrow) is measured from the Bruch membrane opening (red dots) to the nearest point on the internal limiting membrane (red line). The lower left images in each figure show a representation of MRW by 6 sectors and global MRW thickness with a colour code (green equals within normal limits, yellow equals borderline and red equals outside normal limits). The lower right images represent MRW thickness in a linear graph
