Query: Functional Optical Coherence Tomography for Intrinsic Signal
  Optoretinography: Recent Developments and Deployment Challenges   Intrinsic optical signal (IOS) imaging of the retina, also termed as
optoretinography (ORG), promises a noninvasive method for objective assessment
of retinal function. By providing unparalleled capability to differentiate
individual layers of the retina, functional optical coherence tomography (OCT)
has been actively investigated for intrinsic signal ORG measurements. However,
clinical deployment of functional OCT for quantitative ORG is still challenging
due to the lack of a standardized imaging protocol and the complication of IOS
sources and mechanisms. This article aims to summarize recent developments of
functional OCT for ORG measurement, OCT intensity- and phase-based IOS
processing. Technical challenges and perspectives of quantitative IOS analysis
and ORG interpretations are discussed.
