Comparative Diagnostic Accuracy of Ganglion Cell-Inner Plexiform and Retinal Nerve Fiber Layer Thickness Measures by Cirrus and Spectralis Optical Coherence Tomography in Relapsing-Remitting Multiple Sclerosis

Figure 1

Ganglion cell-inner plexiform layer (GCIPL) analysis of the left eye of a patient with relapsing-remitting multiple sclerosis without optic neuritis antecedent in a 6 × 6 × 2 mm macular cube using a Cirrus optical coherence tomography. (a) Deviation map of the GCIPL thickness (red: below percentile 1; yellow: below percentile 5). (b) Sector distribution. (c) GCIPL thickness map, with overlying ellipses showing the dimensions of the analyzed annulus. The outer ellipse has a vertical diameter of 4 mm and the inner ellipse of 1 mm. (d) Horizontal B-scan centered in the fovea, showing the automated segmentation of the GCIPL.
