C. Focus
This Advisory focuses on the perioperative management of
patients who are undergoing spine procedures while they are
positioned prone and receiving general anesthesia. This Advisory
does not address the perioperative management of
patients who receive regional anesthesia or sedation. This
Advisory also does not include other causes of visual loss,
such as cortical blindness. It does not include nonspine surgical
procedures (e.g., cardiac surgery, radical neck dissection).
In addition, this Advisory does not apply to young
children because of the rarity of visual loss in children
younger than 12 years of age undergoing spine surgery.
