Approaches to Aqueous Humor Outflow Imaging

Abstract

The aqueous humor outflow (AHO) tract is the pathway by which fluid travels from the eye’s anterior chamber to drain into the venous circulation. This tract plays an important role in the regulation of eye pressure and is likely key in the pathogenesis of glaucoma. As such, the outflow tract is a target for alteration by medical and surgical treatment approaches. To understand this pathway’s anatomy and physiology, numerous structural and functional studies have been conducted. While the ability to conduct such studies has advanced along with modern imaging approaches, many challenges to accurately assessing its structure and function remain.
