Name of journal: Eye (London, England)Abstract: Retinal ischemia characterizes the underlying pathology in a multitude of retinal diseases that can ultimately lead to vision loss. A variety of novel imaging modalities have been developed to characterize retinal ischemia by measuring retinal oxygenation and blood flow in-vivo. These technologies offer valuable insight into the earliest pathophysiologic changes within the retina and provide physicians and researchers with new diagnostic and monitoring capabilities. Future retinal imaging technologies with the capability to provide affordable, noninvasive, and comprehensive data on oxygen saturation, vasculature, and blood flow mechanics are needed. This review will highlight current and future trends in multimodal imaging to assess retinal blood flow and oxygenation.All authors: Gehlbach PL, Jiramongkolchai K, Marino MJ, Rege AOriginally published: Eye. 2021 Jun 11Fiscal year: FY2022 Fiscal year of original publication: FY2021Digital Object Identifier:
