Visualizing the visual pathway
Bilateral optic nerve confluence at the optic chiasm, anterior cerebral arteries, and anterior communicating artery during endoscopic endonasal resection of a craniopharyngioma compressing chiasm [Fig. 1]. Preoperative visual acuity was 1.4 logMAR units in right (OD) and 0.3 in the left eye with macular branch retinal vein occlusion in OD. Surgery performed using an image-guided protocol with intraoperative monitoring of visual evoked potentials as described by Miyagishima et al. Complete tumor removal was achieved. There was no deterioration of visual function postoperatively.
We highlight the importance of a multidisciplinary approach and application of advanced intraoperative technology in the management of lesions affecting the visual pathway.
