“…39 In a nation-wide United States study from1996-2005, the prevalence of POVL was reported as 3.1 per 10,000 patients following spinal surgery in the prone position. 40 Other large-scale retrospective studies report an incidence ranging from 0.028% in the Johns Hopkins' database of 14,102 spine cases to 0.2% in a study involving 3,450 spine cases.…”

Purpose The purpose of this Continuing Professional Development module is to provide information needed to prepare for and clinically manage a patient in the prone position. Principal findings Prone positioning is required for surgical procedures that involve the posterior aspect of a patient. We searched MEDLINE Ò and EMBASE TM from January 2000 to January 2015 for literature related to the prone position and retrieved only original articles in English. We reviewed the advantages and disadvantages of various equipment used in prone positioning, the physiological changes associated with prone positioning, and the complications that can occur. We also reviewed strategies for the safe conduct and management of position-related complications. Conclusion Increased age, elevated body mass index, the presence of comorbidities, and long duration of surgery appear to be the most important risk factors for complications associated with prone positioning. We recommend a structured team approach and careful selection of equipment tailored to the patient and surgery. The systematic use of checklists is recommended to guide operating room teams and to reduce prone position-related complications. Anesthesiologists should be prepared to manage major intraoperative emergencies (e.g., accidental extubation) and anticipate postoperative complications (e.g., airway edema and visual loss).

“…Clinically, it is divided into anterior and posterior forms by the presence or absence of swelling of the optic nerve head, respectively. 1 Both forms are further classified into arteritic when secondary to vasculitis and nonarteritic when caused by other entities. Nearly all cases of arteritic ION are due to giant cell arteritis.…”

Ischemic optic neuropathy (ION) describes a state of hypoxic injury of the optic nerve. Clinically, ION is divided into anterior and posterior forms defined by the presence or absence of optic disc swelling, respectively. It is further classified as arteritic when secondary to vasculitis, and nonarteritic when not. The site of vascular occlusion for anterior ION from giant cell arteritis is the short posterior ciliary arteries, but mechanical vascular obstruction does not play a role in most nonarteritic cases. Histologically, ION is characterized by axon and glial necrosis, edema, and a sparse mononuclear response. Like other ischemic injuries, the morphologic alternations in the nerve are time dependent. A variant of ION called cavernous degeneration (of Schnabel) features large cystic spaces filled with mucin. Several conditions can histologically mimic cavernous degeneration of the optic nerve. The scarcity of cases of ION examined histologically has contributed to an incomplete understanding of its pathogenesis.
