Figure 1
Example from a preoperative OCT examination of patient #8. In the upper panel, the circular scanning trajectory of 3.4 mm diameter centered on the optic nerve disc is depicted on the scanning laser ophthalmoscopy image. The green circular slice represents the temporal part of peripapillary RNFL. In the bottom panel, the green area marks the evaluated temporal RNFL thickness delineated by the internal limiting membrane (ILM) and the interface between the axonal fibers and the bodies of the ganglion cells (a). Distribution of the temporal RNFL thickness in preoperative and three postoperative visits separately for patients with a grade of compression 0–1 and 2–4. The grade factor was statistically significant (p = 0.180 × 10–6). The lower and upper hinges of the boxplots represent the 25th and 75th percentiles, respectively; the whiskers extend to an outlier but not farther than 1.5 times the interquartile range. The boxplot overlays the individual values represented as gray circles spread along the horizontal dimension to avoid overlapping (b).
