Clinical Applications of Retinal Function Imager

Edited by Prof. Jianhua Wang 

Retinal function imager (RFI) is a versatile imaging system which was adapted in 2004 by Prof. Grinvald from the brain imaging technique. The RFI can image measure retinal blood flow velocity, create non-invasive capillary perfusion maps, and determine blood oximetry. The retinal capillary maps produced by RFI are similar to the en face view of the retinal capillary maps created by optical coherence tomography angiography (OCTA). Most importantly, the measurement of retinal blood flow velocity and flow volume in the small retinal vessels enables the estimate of the retinal tissue perfusion. This thematic series focuses on the recent applications of RFI and aims to publish review articles and original research of the latest discovery using RFI.
