Postoperative Posterior Ischemic Optic Neuropathy After Left Far-Lateral Craniectomy for Resection of Craniocervical Meningioma

This case suggests that PION can occur in the lateral position where there is no direct pressure on the orbits. PION is often not discussed as a potential complication during the preoperative consent process. This case suggests it may be prudent to discuss PION in similar neurosurgical cases. Intraoperative blood transfusion should be considered in prolonged surgeries in the lateral position, where slow blood loss over a long period could be a contributing factor to development of PION.
