      Quantitative progression of retinitis pigmentosa by optical coherence tomography angiography
      Optical coherence tomography angiography (OCT-A) is a non-invasive alternative to fluorescein angiography that allows for the study of the retinal and choroidal vasculatures. In this retrospective cohort study of 28 patients with retinitis pigmentosa (RP), we used OCT-A to quantify changes in perfusion density, foveal avascular zone (FAZ) area, and choriocapillaris blood flow over time and correlated these variables with ellipsoid zone (EZ) line width and best-corrected visual acuity (BCVA ...

      Intraoperative Imaging Modalities and the Potential Role of Speckle Modulating Optical Coherence Tomography
      Maximizing extent of resection has been correlated with improved outcomes in a variety of pediatric and adult brain tumors. 1-11 While gross total resections are often achieved without the use of intraoperative adjuncts, difficulty in distinguishing tumor from normal brain can at times prevent the complete resection of brain tumors. Intraoperative imaging tools have increasingly been embraced with the goal of improving rates of gross total resection. In this review ...

    6. Automatically Determining the Confocal Parameters from OCT B-Scans for Quantification of the Attenuation Coefficients

      Automatically Determining the Confocal Parameters from OCT B-Scans for Quantification of the Attenuation Coefficients
      The attenuation coefficient is a relevant biomarker for many diagnostic medical applications. Recently, the Depth- Resolved Confocal (DRC) technique was developed to automatically estimate the attenuation coefficients from Optical Coherence Tomography (OCT) data with pixel-level resolution. However, DRC requires that the confocal function parameters (i.e., focal plane location and apparent Rayleigh range) be known a priori. In this paper we present the autoConfocal algorithm: a simple, automatic method for ...

      Comparison of cross sectional optical coherence tomography images of elevated optic nerve heads across acquisition devices and scan protocols
      Background Optic nerve head measurements extracted from optical coherence tomography (OCT) show promise for monitoring clinical conditions with elevated optic nerve heads. The aim of this study is to compare reliability within and between raters and between image acquisition devices of optic nerve measurements derived from OCT scans in eyes with varying degrees of optic nerve elevation. Methods Wide angle line scans and narrow angle radial scans through optic nerve ...

      Visible light optical coherence microscopy imaging of the mouse cortex with femtoliter volume resolution
      Most flying-spot Optical Coherence Tomography (OCT) and Optical Coherence Microscopy (OCM) systems use a symmetric confocal geometry, where the detection path retraces the illumination path starting from and ending with the spatial mode of a single mode optical fiber. Here, we describe a visible light OCM instrument that breaks this symmetry to improve transverse resolution without sacrificing collection efficiency in scattering tissue. This was achieved by overfilling a 0.3 ...

      Optical coherence tomography of lymphatic vessel endothelial hyaluronan receptors in vivo
      Optical Coherence Tomography (OCT) imaging of living subjects offers millimeters depth of penetration into tissue while maintaining high spatial resolution. However, because most molecular biomarkers do not produce inherent OCT contrast signals, exogenous contrast agents must be employed to achieve molecular imaging. Here we demonstrate that microbeads (Bs) can be used as effective contrast agents to target cellular biomarkers in lymphatic vessels and can be detected by OCT using a ...

      Optical Coherence Tomography Angiography in Retinal Vein Occlusion: Quantifying Macular Ischemia
      Purpose of Review Optical coherence tomography angiography (OCTA) is a new imaging modality that has the ability to image the retinal vasculature without the use of intravenous dye. This review aims to explore the role of OCTA when used to measure macular ischemia in patients with retinal vein occlusion (RVO). Recent Findings OCTA and fluorescein angiography are highly correlated in their findings related to macular perfusion status in patients with ...

      ELHnet: a convolutional neural network for classifying cochlear endolymphatic hydrops imaged with optical coherence tomography
      Detection of endolymphatic hydrops is important for diagnosing Menieres disease, and can be performed non-invasively using optical coherence tomography (OCT) in animal models as well as potentially in the clinic. Here, we developed ELHnet, a convolutional neural network to classify endolymphatic hydrops in a mouse model using learned features from OCT images of mice cochleae. We trained ELHnet on 2159 training and validation images from 17 mice, using only the ...
