    2. Assessing the Influence of OCT-A Device and Scan Size on Retinal Vascular Metrics

      Assessing the Influence of OCT-A Device and Scan Size on Retinal Vascular Metrics
      Purpose : The purpose of this study was to investigate the effect of device and scan size on quantitative optical coherence tomography angiography (OCT-A) metrics. Methods : The 3 3 mm scans from Optovue AngioVue and Zeiss AngioPlex systems were included for 18 eyes of 18 subjects without ocular pathology. The foveal avascular zone (FAZ) was segmented manually by two observers, from which estimates of FAZ area (using both the nominal image ...

    3. Imaging of Macrophage-Like Cells in Living Human Retina Using Clinical OCT

      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 ...

    4. Optical Coherence Tomography, Fluorescein Angiography, and Electroretinography Features of Niacin Maculopathy: New Insight Into Pathogenesis

      Optical Coherence Tomography, Fluorescein Angiography, and Electroretinography Features of Niacin Maculopathy: New Insight Into Pathogenesis
      Purpose: We describe the features of niacin maculopathy in a 61-year old man using ocular coherence tomography (OCT), fluorescein angiography, and electroretinography (ERG). Methods: A case report is presented. Results: A 61-year-old male presented with decreased visual acuity. Cirrus OCT revealed bilateral cystic macular edema, without leakage on fluorescein angiography. Dark-adapted maximal-flash ERG demonstrated an absent b-wave. Light-adapted flicker responses revealed diminished amplitude and delayed implicit time (IT). Multifocal ERG ...

    5. Automated OCT for after-hours care aids in patient management

      Automated OCT for after-hours care aids in patient management
      asy-to-use automated OCT systems can enhance patient care in high-volume after-hours clinics when traditional scans are typically not available, according to a study. Limited access to diagnostic equipment and skilled imaging personnel can make patient care during after-hours difficult. An automated OCT system available for after-hours use in a high-volume clinic can greatly improve patient care and empower ophthalmologists to make accurate diagnoses, study co-author Richard L. Rosen, MD, ScD ...

    6. 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 ...

    8. Impact of automated OCT in a highvolume eye urgent care setting

      Impact of automated OCT in a highvolume eye urgent care setting
      Background/Aims Optical coherence tomography (OCT) has become standard of care in the diagnosis and management of a myriad of retinal and optic nerve pathology. Access to diagnostic equipment and skilled imaging personnel in the after-hours setting is often limited. We examined the utility and diagnostic indications for automated OCT in a high-volume after-hours clinic within an eye institute. Methods OCT images obtained over a period of 15 months were ...

    9. Earliest Evidence of Preclinical Diabetic Retinopathy Revealed using OCT Angiography (OCTA) Perfused Capillary Density

      Earliest Evidence of Preclinical Diabetic Retinopathy Revealed using OCT Angiography (OCTA) Perfused Capillary Density
      Purpose To compare perfused capillary density (PCD) in diabetic patients and healthy controls using optical coherence tomography angiography (OCTA). Methods Forty controls, 36 diabetics without clinical retinopathy (NoDR), 38 with nonproliferative retinopathy (NPDR), and 38 with proliferative retinopathy (PDR) were imaged using SD-OCT. A 3x3 mm full-thickness parafoveal OCTA scan was obtained from each participant. Following manual delineation of the foveal avascular zone (FAZ), FAZ area, perimeter, and acircularity index ...

    10. MACULAR VORTEX VEIN IN A HIGHLY MYOPIC EYE IMAGED BY OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY

      MACULAR VORTEX VEIN IN A HIGHLY MYOPIC EYE IMAGED BY OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY
      Purpose: To report a case of macular vortex vein imaged with indocyanine green angiography, spectral domain optical coherence tomography, and optical coherence tomography angiography . Methods: Observational case report. Results: A 51-year-old myopic man presented with the complaint of a floater in his left eye for the previous 2 weeks. His visual acuity was 20/25 in the right eye and 20/40 in the left eye. Biomicroscopy was normal. Retinoscopy ...
