Figure 2
Example from a preoperative OCT examination of patient #8. The limited field (inside the green line) represents the nasal half of the fovea used for the quantification of the ganglion cell layer (GCL) thickness. The GCL thickness is color-coded and clearly shows hemifield asymmetry related to the chiasmatic syndrome (a). The distribution of GCL thickness was significantly different between patients with the grade of compression 0–1 and 2–4 (p = 0.024 × 10–6). For the description of the boxplot parameters, see the legend of Fig. 1b (b).
