      To describe patterns of reperfusion in the superficial vascular plexus (SVP), deep capillary plexus (DCP) and choriocapillaris (CC) as detected on optical coherence tomography (OCTA) in cynomogulus macaque monkey model following increase in intraocular pressure by an intravitreal injection. Animal imaging study. Two cynomogulus macaque monkeys. A 100 L intravitreal injection (IVI) of saline was given in one eye of each monkey. Serial OCTA using a Zeiss Plex Elite 9000 ...

    3. The Varying Optical Coherence Tomography Appearance of the Inner Choroid with Age: Possible Explanation and Histologic Correlate

      The Varying Optical Coherence Tomography Appearance of the Inner Choroid with Age: Possible Explanation and Histologic Correlate
      Purpose: To investigate the reflectivity of the structural optical coherence tomography images of the inner choroid as it relates to potential structural composition. Methods: The reflectivity of slab images 29 49 m and 45 65 m below the RPE, obtained with the Zeiss Plex Elite 9000, were evaluated. The mean and standard deviation of a group of subjects with no ocular disorders were determined. Binarization of the images was done ...

    4. NOVEL METHOD FOR IMAGE AVERAGING OF OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY IMAGES

      NOVEL METHOD FOR IMAGE AVERAGING OF OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY IMAGES
      Purpose: To develop a method of averaging optical coherence tomography (OCT) angiography to improve visualization of choriocapillaris structure. Methods: A stack of OCT angiographic data from vascular layers were placed into the red-green-blue channels of a conventional digital color image. The superficial plexus was placed in the blue channel, choriocapillaris in the green, and deep vascular plexus in the red channel. The red-green-blue images derived from nine separate OCT angiographic ...

      SWEPT-SOURCE OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY IMAGE COMPENSATION OF THE CHORIOCAPILLARIS INDUCES ARTIFACTS
      Purpose: To analyze swept-source optical coherence angiography slab images acquired at the default level for the choriocapillaris from the Zeiss PLEX Elite 9000 before and after using a previously described imaging compensation technique. Methods: Eyes of normal subjects, in their 20 seconds and 30 seconds, were evaluated. Angiographic slab images, 20 m in thickness, were taken at the default location of 29 to 49 m below the retinal pigment epithelium ...

    6. Novel biomarker of sphericity and cylindricity indices in volume-rendering optical coherence tomography angiography in normal and diabetic eyes: a preliminary study

      Novel biomarker of sphericity and cylindricity indices in volume-rendering optical coherence tomography angiography in normal and diabetic eyes: a preliminary study
      Purpose Preliminary to evaluate geometric indices (vessel sphericity and cylindricity) for volume-rendered optical coherence tomography angiography (OCTA) in healthy and diabetic eyes. Methods Twenty-six eyes of 13 healthy subjects and 12 eyes of patients with central ischemic, non-proliferative diabetic retinopathy were included. OCTA volume and surface area of the foveal vessels were measured and compared to determine OCTA sphericity and cylindricity indices and surface efficiency (SE). Results The overall average ...

    7. New Proposal For The Pathophysiology Of Type 3 Neovascularization As Based On Multimodal Imaging Findings

      New Proposal For The Pathophysiology Of Type 3 Neovascularization As Based On Multimodal Imaging Findings
      Purpose: To investigate the imaging characteristics of early Type 3 neovascularization and propose a new pathophysiologic sequence for early disease. Methods: Patients were evaluated with a comprehensive ophthalmologic examination to include fundus photography, optical coherence tomography , optical coherence tomography angiography, fluorescein angiography, and volume-rendered optical coherence tomography angiography. Relevant literature was also reviewed. Results: There were 10 eyes of 9 patients who had a mean age of 87 (range 7993 ...

    8. CHARACTERIZING RETINAL–CHOROIDAL ANASTOMOSIS IN MACULAR TELANGIECTASIA TYPE 2 WITH OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY

      CHARACTERIZING RETINAL–CHOROIDAL ANASTOMOSIS IN MACULAR TELANGIECTASIA TYPE 2 WITH OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY
      Purpose: To characterize structural and angiographic findings in macular telangiectasia Type 2 (MacTel 2) and examine associations with visual acuity. Methods: MacTel 2 patients with complete ophthalmologic examination, including fundus photography, autofluorescence, spectral-domain optical coherence tomography, and projection-resolved optical coherence tomography angiography , were retrospectively evaluated. Results: There were 43 eyes of 22 patients with a mean age 63.9 (10.3) years. Six patients had diabetes. Twenty-one eyes (48.8 ...

    9. Volume analysis and display of information in optical coherence tomography angiography

      Volume analysis and display of information in optical coherence tomography angiography
      Computer aided visualization and diagnosis by volume analysis of optical coherence tomography (OCT) angiographic data. In one embodiment, such analysis comprises acquiring an OCT dataset using a processor in conjunction with an imaging system; evaluating the dataset, with the processor, for flow information using amplitude or phase information; generating a matrix of voxel values, with the processor, representing flow occurring in vessels in the volume of tissue; performing volume rendering ...

    10. A Potential of Mechanism of Retinal Injury

      A Potential of Mechanism of Retinal Injury
      Purpose: To investigate the structural optical coherence tomography and related microvascular flow characteristics in eyes with retinal vasculitis. Methods: Regions involved with perivascular infiltration in eyes with retinal vasculitis, but no evidence of large vessel occlusion were evaluated with optical coherence tomography (OCT), OCT angiography, and fluorescein angiography. Results: Ten eyes of 5 patients with a variety of etiologies of retinal vasculitis were evaluated. These patients did not have either ...

      Enhanced Depth Imaging Spectral-Domain Optical Coherence Tomography
      Purpose To describe a method to obtain images of the choroid using conventional spectral-domain (SD) optical coherence tomography (OCT) and to evaluate choroidal thickness measurements using these images. Design Observational case series. Methods The images were obtained by positioning the SD OCT device close enough to the eye to obtain an inverted representation of the fundus in healthy volunteers who did not have pupillary dilation. Seven sections, each comprised of ...
