    3. Mitigating the effects of choroidal hyper- and hypo-transmission defects on choroidal vascularity index assessments using optical coherence tomography

      Mitigating the effects of choroidal hyper- and hypo-transmission defects on choroidal vascularity index assessments using optical coherence tomography
      Background: Changes in choroidal vascularity index (CVI) are associated with multiple choroid-related ocular diseases. CVI is calculated as the area/volume ratio of vessels in the choroid, which could be affected by alterations in regional signal intensities due to hypo-transmission defects (hypoTDs) caused by drusen and retinal pigment epithelium (RPE) detachments, and hyper-transmission defects (hyperTDs) caused by the absence of RPE. To develop a simulation model to verify the CVI ...

      Purpose: Swept-source optical coherence tomography angiography (SS-OCTA) was used to analyze Bruch's membrane (BM) and choriocapillaris (CC) abnormalities in undiagnosed family members with Sorsby macular dystrophy (SMD). Methods: In a family with SMD (TIMP3 Tyr191Cys), SS-OCTA imaging was performed using the 6X6mm scan patter and previously validated algorithms to detect abnormalities in BM and the CC, as well as the presence of reticular pseudodrusen (RPD) and macular neovascularization (MNV ...

    5. Imaging-photoplethysmography-guided optical microangiography

      Imaging-photoplethysmography-guided optical microangiography
      We report a method to image facial cutaneous microvascular perfusion using wide-field imaging photoplethysmography (iPPG) and handheld swept-source optical coherence tomography (OCT). The iPPG system employs a 16-bit-depth camera to provide a 2D wide-field blood pulsation map that is then used as a positioning guidance for OCT imaging of cutaneous microvasculature. We show the results from iPPG and OCT to demonstrate the ability of guided imaging of cutaneous microvasculature, which ...

    6. Automatic geographic atrophy segmentation using optical attenuation in OCT scans with deep learning

      Automatic geographic atrophy segmentation using optical attenuation in OCT scans with deep learning
      A deep learning algorithm was developed to automatically identify, segment, and quantify geographic atrophy (GA) based on optical attenuation coefficients (OACs) calculated from optical coherence tomography (OCT) datasets. Normal eyes and eyes with GA secondary to age-related macular degeneration were imaged with swept-source OCT using 66 mm scanning patterns. OACs calculated from OCT scans were used to generate customized composite en face OAC images. GA lesions were identified and measured ...

    7. Probing elastic anisotropy of human skin in vivo with light using non-contact acoustic micro-tapping OCE and polarization sensitive OCT

      Probing elastic anisotropy of human skin in vivo with light using non-contact acoustic micro-tapping OCE and polarization sensitive OCT
      Skin broadly protects the human body from undesired factors such as ultraviolet radiation and abrasion and helps conserve body temperature and hydration. Skins elasticity and its level of anisotropy are key to its aesthetics and function. Currently, however, treatment success is often speculative and subjective, and is rarely based on skins elastic properties because there is no fast and accurate non-contact method for imaging of skins elasticity.

      OCTA Derived Vessel Skeleton Density Versus Flux and Their Associations With Systemic Determinants of Health
      Purpose: To examine the associations of optical coherence tomography angiography (OCTA)-derived retinal capillary flux with systemic determinants of health. Methods: This is a cross-sectional study of subjects recruited from the African American Eye Disease Study. A commercially available swept-source (SS)-OCTA device was used to image the central 3 3 mm macular region. Retinal capillary perfusion was assessed using vessel skeleton density (VSD) and flux. Flux approximates the number ...

    10. Mitochondrial distribution in the outer plexiform layer of human retina - Does it correlate with reflectivity in OCT?

      Mitochondrial distribution in the outer plexiform layer of human retina - Does it correlate with reflectivity in OCT?
      Mitochondria are organelles essential for cellular metabolism that also contribute reflectivity to optical coherence tomography (OCT) via Mie scattering. To find reflectivity sources, we assessed mitochondrial distribution of outer plexiform layer (OPL) using comprehensive volume electron microscopy. Parafoveal retina of a 21-year-old male donor was subject to serial block-face scanning electron microscopy in 5550 nm voxels. A convolutional neural network (U-Net) was used to train and generate a deep learning ...

    14. Optical Coherence Tomography for Patients with Developmental Disabilities: A Preliminary Study

      Optical Coherence Tomography for Patients with Developmental Disabilities: A Preliminary Study
      Dental radiographs are essential for diagnosis and treatment planning, but are sometimes difficult to acquire for patients with developmental disabilities (PDD). Optical Coherence Tomography (OCT) is a non-ionizing imaging modality that has the potential application as an alternative to dental radiographs for PDD. This study aimed to determine the feasibility of intraoral OCT imaging for PDD. Ten participants were recruited in the Dental Education in the Care of Persons with ...
