Full Text
Bilateral optic nerve confluence at the optic chiasm, anterior cerebral arteries, and anterior communicating artery during endoscopic endonasal resection of a craniopharyngioma compressing chiasm [Figure 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.[1] Complete tumor removal was achieved. There was no deterioration of visual function postoperatively.{Figure 1}
We highlight the importance of a multidisciplinary approach and application of advanced intraoperative technology in the management of lesions affecting the visual pathway.
