    2. Topographic analysis of macular choriocapillaris flow deficits in diabetic retinopathy using swept–source optical coherence tomography angiography

      Topographic analysis of macular choriocapillaris flow deficits in diabetic retinopathy using swept–source optical coherence tomography angiography
      Background The purpose of this study was to investigate the association between diabetic retinopathy (DR) severity and macular choriocapillaris (CC) flow deficit percentage (FD %) in different macular regions using swept-source optical coherence tomography angiography (SS-OCTA). Methods Diabetic patients with SS-OCTA images were graded by severity and retrospectively assessed. CC FD % was calculated in four different regions of the OCTA image: inner, middle, outer, and full-field region. The generalized estimating equations ...

    3. Controlling for Artifacts in Widefield Optical Coherence Tomography Angiography Measurements of Non-Perfusion Area

      Controlling for Artifacts in Widefield Optical Coherence Tomography Angiography Measurements of Non-Perfusion Area
      The recent clinical adoption of optical coherence tomography (OCT) angiography (OCTA) has enabled non-invasive, volumetric visualization of ocular vasculature at micron-scale resolutions. Initially limited to 3mm3mm and 6mm6mm fields-of-view (FOV), commercial OCTA systems now offer 12mm12mm, or larger, imaging fields. While larger FOVs promise a more complete visualization of retinal disease, they also introduce new challenges to the accurate and reliable interpretation of OCTA data. In particular, because of vignetting ...

      BACKGROUND AND OBJECTIVE: To describe a method for visualizing preretinal neovascularization in proliferative diabetic retinopathy (PDR) using optical coherence tomography angiography (OCTA) and report the findings in the surrounding vasculature. PATIENTS AND METHODS: Patients with PDR diagnosed on clinical examination who received OCTA scans using the RTVue XR Avanti (Optovue, Fremont, CA) were evaluated. To visualize preretinal neovascularization, OCT angiograms were segmented to project vasculature above the internal limiting membrane ...

    8. Analysis of Choroidal and Retinal Vasculature in Inherited Retinal Degenerations Using Optical Coherence Tomography Angiography

      Analysis of Choroidal and Retinal Vasculature in Inherited Retinal Degenerations Using Optical Coherence Tomography Angiography
      BACKGROUND AND OBJECTIVE: To describe the retinal vasculature and choriocapillaris, as well as the transition zone between the diseased and healthy tissue, in eyes with inherited retinal degenerations using optical coherence tomography angiography (OCTA). . PATIENTS AND METHODS: Patients with inherited retinal degenerations were recruited for OCTA imaging. Retinal vasculature was assessed for increased intercapillary space and foveal avascular zone abnormalities. Choriocapillaris, retinal pigment epithelium (RPE), and photoreceptor disruption were noted ...

    13. Association of Choroidal Neovascularization and Central Serous Chorioretinopathy With Optical Coherence Tomography Angiography

      Association of Choroidal Neovascularization and Central Serous Chorioretinopathy With Optical Coherence Tomography Angiography
      Importance Choroidal neovascularization (CNV) is a major cause of vision loss in chronic central serous chorioretinopathy (CSCR). Detecting CNV using fluorescein angiography (FA) may be challenging owing to the coexistence of features related to the primary diagnosis of CSCR. Optical coherence tomography angiography (OCTA) allows noninvasive visualization of retinal and choroidal vasculature via motion contrast and may contribute to the unequivocal diagnosis of CNV in this population. Objective To evaluate ...

    1. The Cirrus HD-OCT (Carl Zeiss Meditec), for example, has a very easy system for image acquisition. It's also a very compact device that can be a good choice for practices in which space is limited.

    2. The RTVue-100 is a versatile in strument for general ophthalmology practice...You can perform both anterior and posterior segment imaging with this device, and it also provides very high-quality retinal imaging. The capability to do both retinal and anterior segment imaging in one machine should be a very attractive consideration for a general ophthalmologist.
