    1. Progress in Multimodal En Face Imaging: feature introduction

      Progress in Multimodal En Face Imaging: feature introduction

      This feature issue contains papers that report on the most recent advances in the field of en face optical coherence tomography (OCT) and of combinations of modalities facilitated by the en face view. Hardware configurations for delivery of en face OCT images are described as well as specific signal and image processing techniques tailored to deliver relevant clinical diagnoses. The value of the en face perspective for enabling multimodality is illustrated by several combination modalities.

    2. Methods and apparatus for retina blood vessel assessment with OCT angiography

      Methods and apparatus for retina blood vessel assessment with OCT angiography

      A method of processing a 3D OCT dataset is present. A method according to some embodiments of the present invention includes obtaining an OCT data from the 3D OCT dataset; obtaining an OCTA data from the 3D OCT dataset; performing segmentation for at least one boundary on the OCT data; processing the OCTA data in a region of interest to create at least one image representation by assigning a value to each pixel of each of the image representation; and displaying at least one image representation.

    3. En Face OCT Analysis to Assess the Spectrum of Perivenular Ischemia and Paracentral Acute Middle Maculopathy in Retinal Vein Occlusion

      En Face OCT Analysis to Assess the Spectrum of Perivenular Ischemia and Paracentral Acute Middle Maculopathy in Retinal Vein Occlusion

      Purpose To assess the spectrum of perivenular ischemia in eyes with retinal vascular obstruction (typically central or hemicentral retinal vein obstruction) using en face optical coherence tomography (OCT). Design Retrospective observational case series. Methods Eyes with recent retinal vascular occlusion illustrating paracentral acute middle maculopathy (PAMM) in a perivenular fern-like pattern with en face OCT were evaluated in this study. Multimodal retinal imaging including en face OCT segmentation of the inner nuclear layer was performed in all patients. Color fundus photography and fluorescein angiography (FA) images were used to create a vascular overlay of the retinal veins versus the retinal ...

    4. Optical Coherence Tomography Angiography in Diabetes

      Optical Coherence Tomography Angiography in Diabetes

      Diabetic retinopathy is a progressive microvascular disease that leads to increased vessel permeability, retinal ischemia, and retinal neovascularization. Optical coherence tomography angiography (OCTA) is a novel angiography technique that has the capability to advance our understanding of diabetic eye disease by providing high-resolution images of retinal and choroidal microvasculature blood flow and structure. Using OCTA, the vascular changes of diabetic retinopathy including microaneurysms, retinal non-perfusion, intraretinal microvascular abnormalities, and neovascularization can be clearly visualized. OCTA offers several advantages over fluorescein angiography (FA) in that it is faster, safer, and non-invasive, allows better visualization of retinal vessels in both the superficial ...

    6. Relationships Between Indices of Retinal Thinning as Revealed by Spectral Domain Optical Coherence Tomography, and Visual and Cognitive Impairments in Schizophrenia

      Relationships Between Indices of Retinal Thinning as Revealed by Spectral Domain Optical Coherence Tomography, and Visual and Cognitive Impairments in Schizophrenia

      Schizophrenia is a neuropsychiatric disorder in which visual processing abnormalities are common. An unanswered question in this field is the extent to which some of these functional impairments (e.g., contrast sensitivity) may be due to altered retinal structure and function. This question has gained in importance with two recent studies showing retinal nerve fiber layer (RNFL) thinning in schizophrenia, as revealed by spectral domain optical coherence tomography (SD-OCT). OCT is a noncontact imaging technology that can image retinal structure (including thickness) in vivo with a resolution of 10 microns or less using optical backscattering of light. It has been ...

    7. Imaging Vitreo-Macular Interface Abnormalities In The Coronal Plane By Simultaneous Combined Scanning Laser And Optical Coherence Tomography

      Purpose: To describe vitreo-retinal imaging of eyes with vitreo-macular abnormalities using high-resolution coronal-plane optical coherence tomography (OCT) scanning combined with simultaneous scanning laser ophthalmoscope (SLO) imaging. Methods: A SLO-OCT (OTI, Canada) was used to scan patients with vitreo-macular interface abnormalities including epiretinal membranes, macular hole, incomplete posterior vitreous detachment, vitreo-macular traction syndromes and diabetic and cystoid macular edema. The longitudinal –B scan images and the transverse –C scan images in the coronal plane were used to describe vitreo-macular interface abnormalities. The SLO-OCT simultaneously produces a confocal image of the retina. Results: The longitudinal ‘B’ scan and en-face ‘C’ scan images ...

    8. Simultaneous OCT/SLO/ICG Imaging

      Purpose: To evaluate how information from combined coronal Optical Coherence Tomography (OCT) and confocal laser scanning ophthalmoscopy (SLO) with integrated simultaneous Indocyanine Green dye (ICG) angiography can be used in the diagnosis of a variety of macular pathologies. Methods: A compact chin-rest based OCT/confocal imaging system was used to produce the OCT image and excite fluorescence in ICG dye. The same eye fundus area can be visualized with coronal (C-scans, en-face) OCT and ICG angiography simultaneously. Fast T-scanning (transverse scanning, en-face) is used to build B-scan or C-scan OCT images along with confocal SLO views with and without ICG ...
