    1. Intact Retinal Tissue and Retinal Pigment Epithelium Identified Within A Coloboma By High-Speed, Ultrahigh-Resolution Optical Coherence Tomography

      Intact Retinal Tissue and Retinal Pigment Epithelium Identified Within A Coloboma By High-Speed, Ultrahigh-Resolution Optical Coherence Tomography
      Purpose: The purpose of this study was to report on a posterior segment coloboma manifesting unusual morphology as determined by high-speed, ultrahigh-resolution optical coherence tomography imaging. Methods: A 47-year-old woman with bilateral colobomas was evaluated by fundus examination and high-speed, ultrahigh-resolution optical coherence tomography imaging. Results: Imaging with high-speed, ultrahigh-resolution optical coherence tomography showed intact retinal pigment epithelium within the posterior segment coloboma. Most of the retinal layers seemed to ...

    2. Microvascular oxygen tension and flow measurements in rodent cerebral cortex during baseline conditions and functional activation

      Microvascular oxygen tension and flow measurements in rodent cerebral cortex during baseline conditions and functional activation
      Measuring cerebral oxygen delivery and metabolism microscopically is important for interpreting macroscopic functional magnetic resonance imaging (fMRI) data and identifying pathological changes associated with stroke, Alzheimer's disease, and brain injury. Here, we present simultaneous, microscopic measurements of cerebral blood flow (CBF) and oxygen partial pressure (pO(2)) in cortical microvessels of anesthetized rats under baseline conditions and during somatosensory stimulation. Using a custom-built imaging system, we measured CBF with ...

    3. COMPARISON OF SPECTRAL/FOURIER DOMAIN OPTICAL COHERENCE TOMOGRAPHY INSTRUMENTS FOR ASSESSMENT OF NORMAL MACULAR THICKNESS

      Purpose: The purpose of this study was to report normal macular thickness measurements and assess reproducibility of retinal thickness measurements acquired by a time-domain optical coherence tomography (OCT) (Stratus, Carl Zeiss Meditec, Inc., Dublin, CA) and three commercially available spectral/Fourier domain OCT instruments (Cirrus HD-OCT, Carl Zeiss Meditec, Inc.; RTVue-100, Optovue, Inc., Fremont, CA; 3D OCT-1000, Topcon, Inc., Paramus, NJ). Methods: Forty randomly selected eyes of 40 normal, healthy ...

    7. Ultrahigh speed Spectral / Fourier domain OCT ophthalmic imaging at 70,000 to 312,500 axial scans per second

      Ultrahigh speed Spectral / Fourier domain OCT ophthalmic imaging at 70,000 to 312,500 axial scans per second
      We demonstrate ultrahigh speed spectral / Fourier domain optical coherence tomography (OCT) using an ultrahigh speed CMOS line scan camera at rates of 70,000 - 312,500 axial scans per second. Several design configurations are characterized to illustrate trade-offs between acquisition speed, ... [Opt. Express 16, 15149-15169 (2008)]
