4. Deliberations of an International Panel of Experts on OCTA Nomenclature of nAMD
  
  Explore Ophthalmology Dec 30 2020 Ophthalmology
  
  A panel of imaging experts was assembled to review neovascular age-related macular degeneration optical coherence tomography angiography descriptors published to date, and test agreement on use of these terms, which was found to be low. Optical coherence tomography angiography (OCTA) has been used to identify and characterize macular neovascularization (MNV) secondary to age-related macular degeneration (AMD). 1-4 Many studies have explored OCTA morphological features of MNV that might serve as ...

  $Age- and refraction-related changes in anterior segment anatomical structures measured by swept-source anterior segment OCT$
  Abstract Purpose: To assess the effects of age and refractive status on anterior segment anatomical structures, including the ciliary body, using a new swept-source anterior segment optical coherence tomography (AS-OCT) device. Methods: This prospective observational study included 63 healthy volunteers (mean age: 44.2 years). Images of the anterior segment were obtained using a new swept-source AS-OCT (ANTERION, Heidelberg Engineering GmbH, Heidelberg, Germany) with tracking and image averaging from the ...

9. Evaluation of the inner choroid using OCT angiography
  
  Explore Nature Publishing Group Oct 15 2020 Ophthalmology
  
  The advent of optical coherence tomography angiography (OCTA) has allowed a qualitative and quantitative analysis of the retinal vasculature and the choriocapillaris. With the use of OCTA, several studies evaluated the changes in the choriocapillaris showing how this vascular structure plays a significant role in the pathogenesis of different conditions. This article reviews the current methods of analysis of the choriocapillaris and the relevant findings in different chorioretinal diseases.

  Purpose : The purpose of this study was to evaluate and compare the repeatability of optical coherence tomography angiography (OCTA) derived retinal vascular quantitative metrics using high resolution (HR) versus high speed (HS) acquisition modes. Methods : Macular 4.4 2.9-mm OCTA images from normal, healthy volunteers were captured using both HR (768 A-scans 256 B-scans) and HS (384 A-scans 256 B-scans) acquisition protocols. Vessel density and vessel length density of ...

11. Impact of Scan Tilt on Quantitative Assessments Using Optical Coherence Tomography Angiography
  
  Explore TVST Journal Aug 25 2020 Ophthalmology
  
  Purpose : To investigate the impact of scan tilt on quantitative assessments using swept-source optical coherence tomography angiography (SS-OCTA) in healthy participants. Methods : Healthy participants were imaged with a SS-OCTA system (PLEX Elite 9000; Carl Zeiss Meditec, Inc, Dublin, CA). After a standard scan was obtained, tilted scans were obtained by moving the optical coherence tomography beam entrance position horizontally. The tilting angle was measured from the B-scan image, and the ...

  We read with great interest the correspondence in Lancet by Marinho et al. [ 1 ] describing purported retinal manifestations of coronavirus disease (COVID-19). While there is great interest to understand potential ocular complications of COVID-19 during this pandemic, we have some concerns regarding the interpretation of the fundus and optical coherence tomography (OCT) findings. Marinho et al. examined 12 COVID-19 patients (all confirmed by PCR or antibody testing) with typical systemic ...

  Explore Nature Publishing Group Jun 14 2020 Ophthalmology
  
  Regular drusen, an accumulation of material below the retinal pigment epithelium (RPE), have long been established as a hallmark early feature of nonneovascular age-related macular degeneration (AMD). Advances in imaging have expanded the phenotype of AMD to include another extracellular deposit, reticular pseudodrusen (RPD) (also termed subretinal drusenoid deposits, SDD), which are located above the RPE. We developed an approach to automatically segment retinal layers associated with regular drusen and ...
