      Automated spectroscopic retinal oximetry with visible-light optical coherence tomography
      Accurate, quantitative assessment of retinal blood oxygen saturation ( sO 2 ) may provide a useful early indicator of pathophysiology in several ocular diseases. Here, with visible-light optical coherence tomography (OCT), we demonstrate an automated spectroscopic retinal oximetry algorithm to measure the sO 2 within the retinal arteries (A- sO 2 ) and veins (V- sO 2 ) in rats by automatically detecting the vascular posterior boundary on cross-sectional structural OCT. The algorithm was ...

      Automated detection of photoreceptor disruption in mild diabetic retinopathy on volumetric optical coherence tomography
      Diabetic retinopathy is a pathology where microvascular circulation abnormalities ultimately result in photoreceptor disruption and, consequently, permanent loss of vision. Here, we developed a method that automatically detects photoreceptor disruption in mild diabetic retinopathy by mapping ellipsoid zone reflectance abnormalities from en face optical coherence tomography images. The algorithm uses a fuzzy c-means scheme with a redefined membership function to assign a defect severity level on each pixel and generate ...

      Automated detection of dilated capillaries on optical coherence tomography angiography
      Automated detection and grading of angiographic high-risk features in diabetic retinopathy can potentially enhance screening and clinical care. We have previously identified capillary dilation in angiograms of the deep plexus in optical coherence tomography angiography as a feature associated with severe diabetic retinopathy. In this study, we present an automated algorithm that uses hybrid contrast to distinguish angiograms with dilated capillaries from healthy controls and then applies saliency measurement to ...

      Evaluation of artifact reduction in optical coherence tomography angiography with real-time tracking and motion correction technology
      Artifacts introduced by eye motion in optical coherence tomography angiography (OCTA) affect the interpretation of images and the quantification of parameters with clinical value. Eradication of such artifacts in OCTA remains a technical challenge. We developed an algorithm that recognizes five different types of motion artifacts and used it to evaluate the performance of three motion removal technologies. On en face maximum projection of flow images, the summed flow signal ...

      Practical Handbook of OCT Angiography (Textbook)
      This book is a practical guide to the revolutionary technique of non-invasive, dyeless OCT angiography imaging. This new diagnostic tool complements, and in part replaces, fluorescein angiography. Beginning with an introduction to the principles and interpretation of OCT angiography, the book covers operating principles, recent advances, the future of OCT, and diagnosis of vascular retinopathies. The book describes how this new technology is used to study inner and outer retina ...
