A–D Measurement of retinal nerve fiber layer (RNFL) thickness, using a circular B-scan placed around the optic disc.
Figures are generally photos, graphs and static images that would be represented in traditional pdf publications.
A Confocal scanning laser ophthalmoscopy infrared image shows optic disc with circular scan (diameter: 3.5 mm). B Corresponding spectral domain optical coherence tomography scan. Red marks delineate automatically borders of RNFL layer. C Presentation of RNFL thickness values for individual sectors and global measurement. D Individual measurement graphically compared to a healthy population.
