Current imaging modalities for assessing ocular blood flow in glaucoma

Abstract

Glaucoma may be caused by an interplay of elevated intraocular pressure (IOP), vascular, genetic, anatomical, brain, and immune factors. The direct assessment of ocular hemodynamics offers promise for glaucoma detection, differentiation, and possibly new treatment modalities. All the methods currently in use to measure ocular blood flow have inherent limitations and measure different aspects of ocular blood flow. This review article attempts to provide detailed information on ocular perfusion pressure as well as an overview of the newly developed imaging technologies used to investigate ocular blood flow in glaucoma patients.
