Representative clinical findings of a case with poor visual outcome (case 2). A 74-year-old man with pituitary adenoma with optic nerve bending in the right eye. The preoperative and postoperative best-corrected visual acuities (BCVAs) were 0.82 and 0.10 in the right eye and 0.70 and − 0.08 in the left eye logarithm of the minimum angle of resolution units, respectively. (a) Preoperative sagittal T2-weighted magnetic resonance images. The angle indicated by yellow dotted lines is the optic nerve–canal bending angle (ONCBA); yellow arrowheads indicate optic nerve, and white dotted lines indicate a tumor. The ONCBAs of this case were 73° in the right eye and 39° in the left eye. Therefore, the right eye is the one with optic nerve bending. (b, c) Color fundus photograph showed normal appearance at preoperative visit (B, right eye; C, left eye). (d, e) Ganglion cell layer (GCL) + inner plexiform layer (IPL) deviation map and sector graph of the right eye (left 2 panels) and left eye (right 2 panels) (d, preoperative; e, postoperative visit). A decrease in preoperative GCL + IPL thickness of the right eye is observed in all sectors. A decrease in preoperative GCL + IPL thickness of the left eye is observed in the predominantly nasal region. Postoperative GCL + IPL thickness in almost all sectors was more unremarkable than preoperative GCL + IPL thickness in both eyes.
