      Purpose: Choriocapillaris (CC) flow deficits (FDs) were measured in the areas exposed by tears of the retinal pigment epithelium (RPE) before and after their onset to determine their change over time. Methods: Patients enrolled in a prospective, swept-source optical coherence tomography angiography (SS-OCTA) study were retrospectively reviewed for RPE tears, and scans were evaluated before and after RPE tear formation. Choriocapillaris flow deficits were measured within the bed of the ...

    5. An Atlas of Optical Coherence Tomography (OCT): Elucidating In Vivo Differences of Scar Types Using OCT in Order to Guide Laser Treatment Parameters

      An Atlas of Optical Coherence Tomography (OCT): Elucidating In Vivo Differences of Scar Types Using OCT in Order to Guide Laser Treatment Parameters
      Objective. When using laser therapy to effectively treat scars, the choice of treatment parameters depends on the knowledge accuracy of the underlying scar pathology, which is often difficult to judge by gross physical exam. As such, more quantitative measures are needed. In recent years, optical coherencetomography (OCT) has shown promise as a real-time imaging technology of skin microstructure. A key step in developing a methodology for utilizing OCT to develop ...

    6. Normative Data and Conversion Equation for Spectral-Domain Optical Coherence Tomography in an International Healthy Control Cohort

      Normative Data and Conversion Equation for Spectral-Domain Optical Coherence Tomography in an International Healthy Control Cohort
      Background: Spectral-domain (SD-) optical coherence tomography (OCT) can reliably measure axonal (peripapillary retinal nerve fiber layer [pRNFL]) and neuronal (macular ganglion cell + inner plexiform layer [GCIPL]) thinning in the retina. Measurements from 2 commonly used SD-OCT devices are often pooled together in multiple sclerosis (MS) studies and clinical trials despite software and segmentation algorithm differences; however, individual pRNFL and GCIPL thickness measurements are not interchangeable between devices. In some circumstances ...

      A deep learning model for automated segmentation of geographic atrophy imaged with swept-source optical coherence tomography images
      Purpose: To present a deep-learning algorithm for the segmentation of geographic atrophy (GA) using en face swept-source optical coherence tomography (SS-OCT) images that is accurate and reproducible for the assessment of GA growth over time. Design: Retrospective review of images obtained as part of a prospective natural history study Subjects: Patients with GA (90), early/intermediate AMD (32), healthy controls (16) METHODS: An automated algorithm utilizing scan volume data to ...

    8. PIPE-Net: A pyramidal-input-parallel-encoding network for the segmentation of corneal layer interfaces in OCT images

      PIPE-Net: A pyramidal-input-parallel-encoding network for the segmentation of corneal layer interfaces in OCT images
      Segmentation of corneal layer interfaces in optical coherence tomography (OCT) images is necessary to generate thickness maps used for cornea diagnosis. In this paper, we propose PIPE-Net, a fully convolutional neural network with a pyramidal input, parallel encoders, and a densely connected decoder to segment four corneal layer interfaces. The pyramidal input is encoded using parallel encoders, which allows the network to process a larger receptive field. The encoders are ...

    9. Effect of OCT B-scan density on sensitivity for detection of intraretinal hyperreflective foci in eyes with age-related macular degeneration

      Effect of OCT B-scan density on sensitivity for detection of intraretinal hyperreflective foci in eyes with age-related macular degeneration
      Purpose To evaluate the impact of reducing the density of B-scans in an optical coherence tomography (OCT) volume on the sensitivity for detecting intraretinal hyperreflective foci (IHRF) in eyes with intermediate age-related macular degeneration (AMD) Methods A total of 165 eyes with intermediate AMD and IHRF were evaluated in this retrospective analysis. For each case, Cirrus HD-OCT volumes were imported into the reading center 3D-OCTOR software. The number of IHRF ...

    10. 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 ...

      Swept-Source Optical Coherence Tomography Detection of Bruch’s Membrane and Choriocapillaris Abnormalities in Sorsby Macular Dystrophy
      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 ...

    12. Optical Coherence Tomography Angiography Findings in Sclerochoroidal Calcification

      Optical Coherence Tomography Angiography Findings in Sclerochoroidal Calcification
      Optical coherence tomography angiography (OCT-A) is a modern non invasive imaging technique that may aid in the evaluation of retinal diseases through the assessment of chorioretinal vasculature. The literature regarding OCT-A in sclerochoroidal calcification is scarce. We present the case of a 57-year-old female who was referred to the clinic due to an atypical choroidal lesion in the right eye. OCT-A showed an apparent decrease in the vascular flow of ...

    13. 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 ...
