Background: Patients undergoing surgery in the prone position may be at risk for
postoperative vision loss associated with increased intraocular pressure. The purpose of this …

IMPLICATIONS: This study investigated whether body inclination can improve the increase
in intraocular pressure (IOP) caused by prone positioning in healthy awake volunteers. We …

Background context Postoperative vision loss complicates an estimated 1 in 1,100 prone
spine surgical cases. This complication has been attributed to ischemic optic neuropathy …

Study Design. Parallel group design. Objective. Compare the intraocular pressure
responses in the prone flat versus prone Trendelenburg's position. Summary of Background …

Results: Mean IOP significantly increased (18.91±3.56 mm Hg)(P< 0.001) at the end of
surgery as compared to baseline value 12.85±3.07 mm Hg. As a result mean OPP …

Background Intraocular pressure (IOP) has been shown to increase during prone position
spine surgery. The present study was conducted to evaluate IOP changes and predictive …

Background: Postoperative visual loss occurs more commonly in patients placed prone. The
mechanism may be raised intraocular pressure (IOP) causing an ischemic oculopathy …

Method: After approval by the human studies committee, informed consent was obtained
from patients, scheduled for spine surgery in the prone position. Before commencement of …

Background and objectives: The increased intraocular pressure (IOP)-which decreases
perfusion pressure on the optic nerve-increases by prone positioning (1). The aim of our …

Background Ocular perfusion pressure is commonly defined as mean arterial pressure
minus intraocular pressure (IOP). Changes in mean arterial pressure or IOP can affect ocular …
