    2. In vivo imaging of the hyaloid vascular regression and retinal and choroidal vascular development in rat eyes using optical coherence tomography angiography

      In vivo imaging of the hyaloid vascular regression and retinal and choroidal vascular development in rat eyes using optical coherence tomography angiography
      This study investigates the hyaloid vascular regression and its relationship to the retinal and choroidal vascular developments using optical coherence tomography angiography (OCTA). Normal and oxygen-induced retinopathy (OIR) rat eyes at postnatal day 15, 18, 21, and 24 were longitudinally imaged using OCTA. At each day, two consecutive imaging for visualizing the hyaloid vasculature and the retinal and choroidal vasculatures were conducted. The hyaloid vessel volume and the retinal and ...

    5. Imaging Laser-Induced Choroidal Neovascularization in the Rodent Retina Using Optical Coherence Tomography Angiography

      Imaging Laser-Induced Choroidal Neovascularization in the Rodent Retina Using Optical Coherence Tomography Angiography
      Purpose : The purpose of this study was to evaluate the performance of optical coherence tomography angiography (OCTA) in visualizing laser-induced choroidal neovascularization (CNV) in the rodent retina. Methods : Choroidal neovascularization was induced via laser photocoagulation in 2 male Brown Norway rats and 2 male C57BL/6 mice. For qualitative comparison, the animals were imaged in vivo with OCTA, indocyanine green angiography (ICGA), and fluorescein angiography (FA), and ex vivo with ...

    6. Retinal and Choroidal Changes and Visual Outcome in Central Retinal Artery Occlusion: An Optical Coherence Tomography Study

      Retinal and Choroidal Changes and Visual Outcome in Central Retinal Artery Occlusion: An Optical Coherence Tomography Study
      Purpose To investigate the retinal and choroidal changes using spectral-domain optical coherence tomography (SD-OCT) and to identify factors associated with visual outcome in eyes with central retinal artery occlusion (CRAO). Design Retrospective observational case series Methods Setting : Institutional Patients: A total of 134 eyes diagnosed with acute (symptom onset 7 days) nonarteritic CRAO examined with SD-OCT at baseline and follow-up visits. Observations: Based on fundoscopic and angiographic findings, CRAO was ...

    8. Macular Hole Formation Secondary to Bacterial Septic Embolism Demonstrated by Serial Spectral-domain Optical Coherence Tomography Imaging

      Macular Hole Formation Secondary to Bacterial Septic Embolism Demonstrated by Serial Spectral-domain Optical Coherence Tomography Imaging
      Purpose : To describe a case of macular hole (MH) formation secondary to bacterial septic embolism and demonstrate the changing thereof using serial spectral-domain optical coherence tomography (SD-OCT) images. Methods : A single case report. Results : A 69-year-old woman who had been diagnosed with Klebsiella pneumonia septicemia was referred for decreased vision in her left eye. Impending MH was detected by SD-OCT and retinitis with multiple retinal hemorrhages by funduscopy. One week ...

    10. Morphologic Characteristics of Retinal Arterial Macroaneurysm and Its Regression Pattern on Spectral-Domain Optical Coherence Tomography

      Morphologic Characteristics of Retinal Arterial Macroaneurysm and Its Regression Pattern on Spectral-Domain Optical Coherence Tomography
      Purpose: To investigate morphologic characteristics of retinal arterial macroaneurysm (RAM) and its regression pattern using spectral-domain optical coherence tomography. Methods: This observational case series included six eyes of six patients with RAM. All patients had undergone repeated comprehensive ophthalmologic examination, including measurement of best-corrected visual acuity, slit-lamp biomicroscopy, indirect fundus examination, fundus photography, fluorescein angiography, and spectral-domain optical coherence tomography (Spectralis OCT). Morphologic findings of RAM on spectral-domain optical coherence ...
