Figure 6
Representative case images of patients with chiasmal compression and control images of a healthy eye. OCT-A en-face images of patients with pituitary adenoma who underwent transsphenoidal tumor resection (Top) and color-coded density maps of the patients (Middle) and a healthy control (Bottom) in the radial peripapillary capillary (RPC) segment (A), the superficial retinal capillary plexus (SRCP) (B), and the deep retinal capillary plexus (DRCP). (C) Color-coded density maps show automated measurements of the vessel density with percentages via auto-segmentation. Vessel densities of the RPC segment and SRCP were lower in the patient cases than in the control. Figures (D–G) show the preoperative visual field with temporal hemianopsia (D), disc photography with band atrophy (E), the peripapillary retinal nerve fiber layer thickness map (F), and the ganglion cell layer complex thickness map (G) in patients with chiasmal compression. Both maps (F,G) show significant thinning. Figures H and I show the peripapillary retinal nerve fiber layer thickness map (H) and the ganglion cell layer complex thickness map (I) in the healthy control.
