Abnormal Systemic and Ocular Vascular Response to Temperature Provocation in Primary Open-Angle Glaucoma Patients: A Case for Autonomic Failure?

Abstract

Cold provocation elicits a different blood pressure, and ocular blood flow response in patients with primary open-angle glaucoma compared with control subjects. These findings suggest a systemic autonomic failure and ocular vascular dysregulation in POAG patients.
