Perioperative Vision Loss: Considerations and Management.

Perioperative vision loss (POVL) associated with routine surgical procedures is a rare but catastrophic event. Although no clear direct cause of POVL has been determined, it is theorized that decreased ocular perfusion pressure of the optic nerve is responsible for POVL. This article will investigate theories as to why POVL occurs, risk factors associated with POVL, anatomy related to POVL, preventive measures that may help to reduce risk of POVL, and interventions that the anesthesia provider can implement.
