The Relationship between Low Ocular Perfusion Pressure with Acute Non-Arteritic Anterior Ischemic Optic Neuropathy
Author(s): Xiaotang Wang*, Tao Lei, Yong Wang and Runsheng Wang
Objective: To investigate the relationship between low
ocular Perfusion Pressure (OPP) with Acute Non-Arteritic
Anterior Ischemic Optic Neuropathy (ANAION).
Methods: Thirty-nine patients (39 eyes) with ANAION from
July 2010 to December 2016 were retrospectively analysed.
The 24-h Intraocular Pressure (IOP) in sitting position was
measured by non-contact tonometer. The brachial artery
Systolic Blood Pressure (SBP) and Diastolic Blood Pressure
(DBP) were simultaneously measured by electrocardiogram
monitor. The 24-h OPP was calculated according to the
measured blood pressure and IOP: OPP=45% DBP-IOP.
OPP<10 mmHg was defined as low OPP. Sudden visual
acuity declining or visual field defect was recorded as the
attack of ANAION. The correlation between low OPP and
ANAION was analysed.
