We summarize the unique features of using VIS-OCT in comparison with near-infrared OCT (NIR-OCT), including ultra-high resolution, retinal microvascular oximetry, and reflectance spectroscopy. The ultra-high resolution is granted by the shorter wavelengths in the visible light range ~500-650 nm, as compared with the conventional OCT wavelengths >800 nm. Detailed sub-bandings in the inner plexiform layer and outer segment of photoreceptors, as well as in the retinal pigment epithelium and Bruch's membrane, are consistently resolved in VIS-OCT. The three-dimensional resolving capacity of VIS-OCT allows better isolation of hemoglobin absorption features, allowing blood oxygen saturation (SO<sub>2</sub>) calculation in retinal microvasculature. Oximetry calculations were performed down to the capillary level in humans, albeit through massive averaging, which was unattainable by previous methods.

Clinical management can benefit from assessing photoreceptor mediated visual function, such as for progression monitoring.

The emerging optoretinography (ORG) technologies promise noninvasive, objective, and highly sensitive markers of photoreceptor function. ORG is an umbrella term that covers several imaging modalities that use intrinsic optical signal, i.e., without dyes or labeling agents, to quantify photoreceptor responses to light. Early studies showed stimulus-evoked light scattering and morphological changes in isolated photoreceptor and retina, which provided the experimental foundation for subsequent inquires <i>in vivo</i>. Technology advancements allowed for optically quantifying photoreceptor light responses in live human subjects using two-dimensional (2D) fundus photography and 3D optical coherence tomography (OCT). The integration of adaptive optics (AO) with OCT enabled direct measurements of outer segment length changes of individual human photoreceptors, revealing essential steps of the phototransduction cascades. In an effort to enlarge measurement field of view, ease imaging workflow, and improve accessibility, more recent studies investigated ORG techniques without the need to resolve or track individual cells. Clinical ORG imaging culminated in demonstrating highly sensitive and reliable detection of photoreceptor dysfunction in patients with degenerative retinal diseases.
