    2. Monitoring Cerebral Hemodynamics Following Optogenetic Stimulation via Optical Coherence Tomography

      Monitoring Cerebral Hemodynamics Following Optogenetic Stimulation via Optical Coherence Tomography
      In this article, spectral domain optical coherence tomography is used to measure the hemodynamic response induced by optogenetic stimulation in the somatosensory cortex of transgenic mice. By analyzing the 3-D angiograms and Doppler measurements produced by coherence tomography, we observed significant increase in blood flow as a result of increased vessel diameter and blood velocity following optical stimulation of cortical neurons. Such distinct responses were not observed in control experiments ...

    5. SPARSE AND LOW RANK DECOMPOSITION BASED BATCH IMAGE ALIGNMENT FOR SPECKLE REDUCTION OF RETINAL OCT IMAGES

      SPARSE AND LOW RANK DECOMPOSITION BASED BATCH IMAGE ALIGNMENT FOR SPECKLE REDUCTION OF RETINAL OCT IMAGES
      Optical Coherence Tomography (OCT) in an emerging technique in the field of biomedical imaging, with applications in ophthalmology, dermatology, coronary imaging etc. Due to the underlying physics, OCT images usually suffer from a granular pattern, called speckle noise, which restricts the process of interpretation. Here, a sparse and low rank decomposition based method is used for speckle reduction in retinal OCT images. In this technique, at first, several OCT images ...

    6. State-of-the-Art in Retinal Optical Coherence Tomography Image Analysis

      State-of-the-Art in Retinal Optical Coherence Tomography Image Analysis
      Optical Coherence Tomography (OCT) is one of the most emerging imaging modalities that has been used widely in the eld of biomedical imaging. From its emergence in 1990's, plenty of hardware and software improvements have been made. Its applications range from ophthalmology to dermatology to coronary imaging etc. Here, the focus is on applications of OCT in ophthalmology and retinal imaging. OCT is able to non- invasively produce cross-sectional ...

    8. Rapid, Accurate, and Non-Invasive Measurement of Zebrafish Axial Length and Other Eye Dimensions Using SD-OCT Allows Longitudinal Analysis of Myopia and Emmetropization

      Rapid, Accurate, and Non-Invasive Measurement of Zebrafish Axial Length and Other Eye Dimensions Using SD-OCT Allows Longitudinal Analysis of Myopia and Emmetropization
      Refractive errors in vision can be caused by aberrant axial length of the eye, irregular corneal shape, or lens abnormalities. Causes of eye length overgrowth include multiple genetic loci, and visual parameters. We evaluate zebrafish as a potential animal model for studies of the genetic, cellular, and signaling basis of emmetropization and myopia. Axial length and other eye dimensions of zebrafish were measured using spectral domain-optical coherence tomography (SD-OCT). We ...

    9. A combined method to quantify the retinal metabolic rate of oxygen using photoacoustic ophthalmoscopy and optical coherence tomography

      A combined method to quantify the retinal metabolic rate of oxygen using photoacoustic ophthalmoscopy and optical coherence tomography
      Quantitatively determining physiological parameters at a microscopic level in the retina furthers the understanding of the molecular pathways of blinding diseases, such as diabetic retinopathy and glaucoma. An essential parameter, which has yet to be quantified noninvasively, is the retinal oxygen metabolic rate (rMRO 2 ). Quantifying rMRO 2 is challenging because two parameters, the blood flow rate and hemoglobin oxygen saturation (sO 2 ), must be measured together. We combined photoacoustic ...

    10. Zebrafish as a Model to Study Emmetropization, Refractive Error, and Retinal Substructure using Spectral Domain-Optical Coherence Tomography

      Zebrafish as a Model to Study Emmetropization, Refractive Error, and Retinal Substructure using Spectral Domain-Optical Coherence Tomography
      Purpose : Spectral-domain optical coherence tomography (SD-OCT) accurately measures the anatomy and dimensions of the eye in vivo . Here, we characterize emmetropization of wild-type zebrafish, myopia onset in bugeye/lrp2 mutants, and visualize the highly ordered cone photoreceptor mosaic by SD-OCT. We combine high resolution visualization with an animal model amenable to genetic manipulation that can be used to study candidate genes for refractive error and other ocular diseases. Methods : Eye ...
