Change in Intraocular Pressure and Ocular Perfusion Pressure Due to Trendelenburg Positioning.

Significance: This study increases foundational knowledge about the dynamic relationships between intraocular pressure (IOP), blood pressure (BP), and mean ocular perfusion pressure (MOPP) in the setting of steep Trendelenburg positioning and may inform medical decision making for patients in which this positioning is planned.

Purpose: The purpose of this study was to explore the demographic and clinical factors related to IOP, MOPP, and BP change during Trendelenburg positioning in a large sample of subjects.

Methods: A single-cohort interventional study was conducted at the American Academy of Optometry 2017 annual meeting.
