Figure 1

illustrates an optic disc photograph (top left) of a right eye with advanced glaucomatous optic neuropathy and diffuse thinning of the neural rim, and corresponding double arcuate scotoma (top right) using standard automated perimetry. Time-domain (bottom left) and Fourier-domain (bottom right) optical coherence tomography images demonstrate diffuse thinning of the RNFL (average thickness 47.25μ and 48μ, respectively), outside 95% confidence limits of age-matched normal subjects. Note that 90-degree quadrantic RNFL assessments using TD-OCT (64 A-scans/quadrant) were generated using an average of three segments; corresponding 90-degree quadrantic RNFL assessments using FD-OCT (250 A-scans/quadrant) were generated using an average of four segments.
