Advances in optical coherence tomography (OCT) imaging technology and techniques. Advances are categorized into emerging advances for clinical use, advances for basic science/research, and recent advances in available technology.

Advances in OCT	Summary of Primary Advancement	References
	Emerging Advances for Clinical Use
Visible-Light (Vis) OCT	Utilizes visible light illumination for OCT as opposed to commonly used near-infrared (NIR) light to capture fine details of the retina	[17,18]
Adaptive Optics (AO) OCT	Wavefront correcting component and computational controller software to compensate for aberrations and quality degradation, increasing the quality of OCT images.	[19,20]
Polarization Sensitive (PS) OCT	Measures and quantifies the polarization and depolarization of tissue for precision, high-quality imaging of retinal pigment epithelium layers	[21,22]
High-Resolution OCT (High-Res OCT)	Broadened bandwidth of the OCT light source to improve axial resolution and capture clearer details of the retinal microstructures and microvasculature.	[23,24]
	Advances for Basic Science/Research
Full-Field (FF) and Dynamic Full-Field (DFF) OCT	Acquires images with charge coupled device cameras in 2D enface orientation at different depths for high resolution images at the cellular level.	[25,26]
	Recent Advances in Available Technology
Wide-field (WF) and Ultrawide-field (UWF) OCT	Increased field of view to 40–55 degrees with wide-field OCT and up to 200 degrees with ultrawide-field OCT	[27,28]
Hand-Held and Intraoperative OCT (iOCT)	Hand-held OCT is portable OCT technology that is particularly useful for infants and bed ridden patients. Intraoperative OCT (microscope integrated) allows for image guidance and real-time feedback during ophthalmic surgery.	[29,30]
At-Home OCT	At-home, self-imaging OCT that allows for more frequent imaging and good agreement when compared to in-clinic OCT for more precise management of retinal diseases.	[31,32]
