    1. Using optical coherence tomography angiography in assessment of the anti-vascular endothelial growth factor effect for pathological vascular tissue in age-related macular degeneration and polypoidal choroidal vasculopathy

      Using optical coherence tomography angiography in assessment of the anti-vascular endothelial growth factor effect for pathological vascular tissue in age-related macular degeneration and polypoidal choroidal vasculopathy

      Purpose: Using optical coherence tomography angiography to assess and compare changes in pathological vascular tissue, including choroidal neovascularization in neovascular age-related macular degeneration and polypoidal complex in polypoidal choroidal vasculopathy, after treatment with anti-vascular endothelial growth factor. Methods: This is a retrospective observational case series study. Clinical data were collected, including that on the best-corrected visual acuity and images of spectrum domain optical coherence tomography and optical coherence tomography angiography of consecutive patients with macula-involved lesions, active pathological vascular tissue in neovascular age-related macular degeneration, and polypoidal complex in polypoidal choroidal vasculopathy who were treated with anti-vascular endothelial growth factor ...

    2. Association of Body Fluid Expansion With Optical Coherence Tomography Measurements in Diabetic Retinopathy and Diabetic Macular Edema

      Association of Body Fluid Expansion With Optical Coherence Tomography Measurements in Diabetic Retinopathy and Diabetic Macular Edema

      Purpose : To evaluate associations of body fluid status with optical coherence tomography measurements in patients with diabetic retinopathy (DR). Methods : This prospective, cross-sectional study enrolled a total of 104 eyes from 104 patients with diabetes mellitus for fundus evaluations of DR and optical coherence tomography examinations. DR severity was graded via fundus photography. Systemic body fluid status was recorded via a body composition monitor with output values of total body water, extracellular water (ECW), intracellular water, and overhydration (OH). Relative overhydration (ROH) was defined as OH/ECW. Volume overload was defined as ROH ≥7%. Correlations of central subfield thickness (CST ...

    3. Optical Coherence Tomography Angiography for Assessment of the 3-Dimensional Structures of Polypoidal Choroidal Vasculopathy

      Optical Coherence Tomography Angiography for Assessment of the 3-Dimensional Structures of Polypoidal Choroidal Vasculopathy

      Importance Investigating the quantitative 3-dimensional (3-D) anatomy of polypoidal complex is important for a better understanding of the pathogenesis of polypoidal choroidal vasculopathy (PCV). Objective To quantitatively evaluate the 3-D characteristics of polypoidal structures, branching vascular networks (BVNs), and origin of PCV using optical coherence tomography angiography (OCTA) and multiple image systems. Design, Setting, and Participants A prospective, observational study was conducted in 47 consecutive Taiwanese patients (47 eyes) from May 21, 2015, to April 30, 2017. All participants were scanned with the Optovue-RTVue-XR-Avanti OCTA system. Patients in whom PCV was identified on OCTA were examined to define characteristics and ...

    4. Quantitative optical coherence tomography findings in a 4-year-old boy with typical morning glory disk anomaly

      Morning glory disk anomaly (MGDA) is a congenital malformation of the optic disk that is usually unilateral. It has characteristic fundus findings, including enlarged optic disk opening and funnel-shaped excavation of the peripapillary fundus. Optical coherence tomography (OCT) with micrometer resolution and cross-sectional imaging capabilities can provide detailed information about the structure of the living eye. Some reports have used OCT to demonstrate the structure of the disk in older patients with MGDA but, to our knowledge, no quantitative OCT report concerning a child with MGDA has been published previously
