      Retinal specialist versus artificial intelligence detection of retinal fluid from optical coherence tomography: AREDS2 10-year Follow-On
      Purpose To evaluate the performance of retinal specialists in detecting retinal fluid presence in spectral domain optical coherence tomography (SD-OCT) macular volume scans from eyes with age-related macular degeneration (AMD), and to compare performance with the artificial intelligence (AI)-based Notal OCT Analyzer (NOA). Design Prospective comparison of retinal fluid grades from human retinal specialists and the NOA on SD-OCT scans from two commonly used devices (Cirrus and Spectralis). Participants ...

      Double diversity optical coherence tomography
      This article provides theoretical analysis for a new generation of optical coherence tomography (OCT) scanners to overcome some main limitations of the technology. In the new design, exposure and detection are not limited to plane-waves that enter or reflect back from the sample exclusively orthogonally. Instead, the sample is scanned by more complex radiation patterns such as spherical or partially spherical light waves. Images that are generated based on this ...

      Imaging of Macrophage-Like Cells in Living Human Retina Using Clinical OCT
      Purpose : To image retinal macrophages at the vitreoretinal interface in the living human retina using a clinical optical coherence tomography (OCT) device. Methods : Eighteen healthy controls and three patients with retinopathies were imaged using a clinical spectral-domain OCT. In controls, 10 sequential scans were collected at three different locations: (1) 9 degrees temporal to the fovea, (2) the macula, and (3) the optic nerve head (ONH). Intervisit repeatability was evaluated ...

      Noise reduction in supercontinuum sources for OCT by single-pulse spectral normalization
      Supercontinuum (SC) sources offer high illumination power from a single-mode fiber with large spectral bandwidth including the visible spectrum, which is a growing application area for optical coherence tomography (OCT). However, SC spectra suffer from pulse-to-pulse variations, increasing noise in the resulting images. By simultaneously collecting a normalization spectrum, OCT image noise can be reduced by more than half (7 dB) for single pulses without any pulse averaging using only ...

      Standard 6 mm Compared to Wide Field 16.5 mm Optical Coherence Tomography for Staging of Posterior Vitreous Detachment
      Objective To assess whether 6 mm optical coherence tomography (OCT) scans, which image the macula, can distinguish complete from partial posterior vitreous detachment (PVD) in comparison to 16.5 mm OCT scans, which image the macula, optic nerve, and midperiphery. Design Retrospective cross-sectional study. Subjects We compared 6 mm and 16.5 mm scans in 157 eyes of 157 retina clinic patients (mean age 50 years; range 1064) with diabetic ...

      Platform for quantitative multiscale imaging of tissue composition
      Changes in the multi-level physical structure of biological features going from cellular to tissue level composition is a key factor in many major diseases. However, we are only beginning to understand the role of these structural changes because there are few dedicated multiscale imaging platforms with sensitivity at both the cellular and macrostructural spatial scale. A single platform reduces bias and complications from multiple sample preparation methods and can ease ...

      Effect of partial posterior vitreous detachment on spectral-domain optical coherence tomography retinal nerve fibre layer thickness measurements
      Background/aims To assess the effect of partial posterior vitreous detachment (pPVD) on spectral-domain optical coherence tomography (OCT) peripapillary retinal nerve fibre layer thickness (RNFL) measurements. Methods Spectral-domain OCT RNFL thickness measurements were obtained from 684 consecutive patients who were seen in the Massachusetts Eye and Ear Glaucoma Service. Of these patients, we compared RNFL thickness measurements between 101 eyes of 101 glaucoma suspects who met inclusion criteria (55 eyes ...

      Assessing the Use of Incorrectly Scaled Optical Coherence Tomography Angiography Images in Peer-Reviewed Studies
      Importance Individual differences in axial length affect the lateral magnification of in vivo retinal images and as a result can affect the accuracy of quantitative measurements made from these images. As measurements from optical coherence tomography angiography (OCTA) images are becoming increasingly used in the diagnosis and monitoring of a wide range of diseases, evaluating which studies use correctly scaled images is crucial to their interpretation. Objective To perform a ...
