    3. Optical coherence tomography angiography in age-related macular degeneration: The game changer

      Optical coherence tomography angiography in age-related macular degeneration: The game changer
      Optical coherence tomography angiography is one of the biggest advances in ophthalmic imaging. It enables a depth-resolved assessment of the retinal and choroidal blood flow, far exceeding the levels of detail commonly obtained with dye angiographies. One of the first applications of optical coherence tomography angiography was in detecting the presence of choroidal neovascularization in age-related macular degeneration and establishing its position in relation to the retinal pigmented epithelium and ...

    4. Optical Coherence Tomography Angiography in Healthy Subjects and Diabetic Patients

      Optical Coherence Tomography Angiography in Healthy Subjects and Diabetic Patients
      Fluorescein angiography and indocyanine green angiography provide information about the normal retinal and choroidal vascular perfusion. They allow the evaluation of different diseases and increase the capability to define and diagnose several pathological conditions. Fluorescein angio graphy is the gold standard in imaging the retinal vascular bed and its changes, although not all the different layers of the capillary network can be visualized in a bidimensional examination. Optical coherence tomography ...

    7. Optical Coherence Tomography Angiography In Patients With BehÇEt Uveitis

      Optical Coherence Tomography Angiography In Patients With BehÇEt Uveitis
      Purpose: To describe optical coherence tomography angiography (OCTA) findings in eyes with Behet uveitis (BU) and to compare these findings with those of fluorescein angiography (FA). Methods: Prospective, comparative, cross-sectional study. Patients presenting with clinically active BU involving the posterior segment were evaluated using FA, spectral domain optical coherence tomography (SD-OCT), and OCTA. Optical coherence tomography angiograms were reviewed and analyzed. Foveal avascular zone areas and vessel densities were also ...

      Optical Coherence Tomography-Angiography of Macular Features after Proton Beam Radiotherapy for Small Choroidal Melanoma
      Purpose To describe the macular features of patients treated with proton beam therapy for choroidal melanoma (CM), using the optical coherence tomography-angiography (OCTA). Design Retrospective case-control study. Methods This study included patients treated with proton beam radiotherapy (PBR) for a small CM. Only patients that had received 100% of the dose 60 GyEBR to the macular area were included in the analysis. All the patients have undergone a full ophthalmological ...

    9. Retinal Microvasculature in Nonproliferative Diabetic Retinopathy: Automated Quantitative Optical Coherence Tomography Angiography Assessment

      Retinal Microvasculature in Nonproliferative Diabetic Retinopathy: Automated Quantitative Optical Coherence Tomography Angiography Assessment
      Purpose: To perform a qualitative and quantitative assessment of the foveal microvasculature in eyes with diabetic maculopathy using optical coherence tomography angiography (OCT-A). Methods: Retrospective case series of 48 eyes with diabetic maculopathy and 47 healthy eyes evaluated by Spectralis OCT-A. Perifoveal arcade disruptions, linear vascular dilations, microaneurysms, intraretinal microvascular abnormalities and flow-void areas were qualitatively analyzed on OCT angiograms both for the superficial (SCP) and deep (DCP) capillary plexuses ...
