Compact Monocular Video‐Ophthalmoscope to Measure Retinal Reflectance Changes to Flicker Light Stimuli

Journal of Biophotonics, EarlyView.
This study presents a compact monocular VO that captures high‐frame‐rate retinal videos of the ONH during flicker light stimulation. The device demonstrated its ability to detect flicker‐induced changes in retinal parameters related to blood flow in healthy subjects, providing insights into temporal and spatial retinal variations.

A practical guide to optical coherence tomography angiography interpretation

International Journal of Retina and Vitreous, 2020
Background Optical coherence tomography angiography (OCTA) can image the retinal vasculature in vivo, without the need for contrast dye. This technology has been commercially available since 2014, however, much of its use has been limited to the research

Deconvolution Techniques in Optical Coherence Tomography: Advancements, Challenges, and Future Prospects

Laser &Photonics Reviews, EarlyView.
This review explores deconvolution techniques in optical coherence tomography (OCT), addressing resolution degradation from point‐spread functions (PSF). It reviews foundational principles (e.g., Richardson‐Lucy deconvolution) to advanced AI‐driven methods, emphasizing clinical translation and interdisciplinary collaboration. Real‐world implementations

Multidimensional en-face OCT imaging of the retina. [PDF]

, 2009
Fast T-scanning (transverse scanning, en-face) was used to build B-scan or C-scan optical coherence tomography (OCT) images of the retina. Several unique signature patterns of en-face (coronal) are reviewed in conjunction with associated confocal images ...
