    3. Photoreceptor layer thinning is an early biomarker for age-related macular degeneration: Epidemiological and genetic evidence from UK Biobank optical coherence tomography data

      Photoreceptor layer thinning is an early biomarker for age-related macular degeneration: Epidemiological and genetic evidence from UK Biobank optical coherence tomography data
      Objective: Despite widespread use of optical coherence tomography (OCT), an early-stage imaging biomarker for age-related macular degeneration (AMD) has not been identified. Pathophysiologically, the timing of drusen accumulation in relation to photoreceptor degeneration in AMD remains unclear, as are the inherited genetic variants contributing to these processes. Here, we jointly analyzed OCT, electronic health record, and genomic data to characterize the time sequence of changes in retinal layer thicknesses in ...

    4. Quantification metrics for telangiectasia using optical coherence tomography

      Quantification metrics for telangiectasia using optical coherence tomography
      Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant disorder that causes vascular malformations throughout the body. The most prevalent and accessible of these lesions are found throughout the skin and mucosa, and often rupture causing bleeding and anemia. A recent increase in potential HHT treatments have created a demand for quantitative metrics that can objectively measure the efficacy of new and developing treatments. We employ optical coherence tomography (OCT)-a ...

    6. Xenopus Tadpole Craniocardiac Imaging Using Optical Coherence Tomography

      Xenopus Tadpole Craniocardiac Imaging Using Optical Coherence Tomography
      Optical coherence tomography (OCT) imaging can be used to visualize craniocardiac structures in the Xenopus model system. OCT is analogous to ultrasound, utilizing light instead of sound to create a gray-scale image from the echo time delay of infrared light reflected from the specimen. OCT is a high-speed, cross-sectional, label-free imaging modality, which can outline dynamic in vivo morphology at resolutions approaching histological detail. OCT imaging can acquire 2D and ...

    9. The long-term effects of anti-vascular endothelial growth factor therapy on the optical coherence tomography angiographic appearance of neovascularization in age-related macular degeneration

      The long-term effects of anti-vascular endothelial growth factor therapy on the optical coherence tomography angiographic appearance of neovascularization in age-related macular degeneration
      Background The short-term effects of anti-vascular endothelial growth factor (anti-VEGF) treatment on macular neovascularization (MNV) morphology is well described, but long-term studies on morphologic changes and correlation of such changes to the type of MNV have not been conducted. This study aims to determine if different types of MNVs in neovascular AMD (nAMD) behave differently with anti-VEGF treatment as visualized on optical coherence tomography angiography (OCTA). Methods Treatment-nave nAMD patients ...
