    2. Temporal evolution of low-coherence reflectrometry signals in photoacoustic remote sensing microscopy

      Temporal evolution of low-coherence reflectrometry signals in photoacoustic remote sensing microscopy
      Recently, a new noncontact reflection-mode imaging modality called photoacoustic remote sensing (PARS) microscopy was introduced providing optical absorption contrast. Unlike previous modalities, which rely on interferometric detection of a probe beam to measure surface oscillations, the PARS technique detects photoacoustic initial pressures induced by a pulsed laser at their origin by monitoring intensity modulations of a reflected probe beam. In this paper, a model describing the temporal evolution from a ...

      Caught between a doc and a hard place
      The Optical Coherence Tomography is vital to assessing the need for an eye inoculation to prevent the disease’s escalation, and further loss of sight: Cutting the cost and frequency of these tests will not only further elevate patient stress, but increase future health care costs by having to provide costly magnifiers and specialized eyewear, with government providing 75 per cent of the cost. I am loathe to criticize without ...

    4. Optical Coherence Tomography in the Diagnosis and Management of Optic Neuritis and Multiple Sclerosis

      Optical Coherence Tomography in the Diagnosis and Management of Optic Neuritis and Multiple Sclerosis
      Optic neuritis (ON) is an inflammatory optic nerve injury, which is strongly associated with multiple sclerosis (MS). Optical coherence tomography (OCT) has the potential to provide a reliable means of capturing axonal deficits, which can be paired to tests of visual function to provide a structuralfunctional paradigm of brain injury. In this respect, the eye provides a unique view into the effects of central nervous system inflammation, which may enhance ...

    5. Progressive Loss of Cones in Achromatopsia: An Imaging Study using Spectral-Domain Optical Coherence Tomography

      Progressive Loss of Cones in Achromatopsia: An Imaging Study using Spectral-Domain Optical Coherence Tomography
      Purpose: Achromatopsia (ACHM) is a congenital autosomal recessive cone disorder with a presumed stationary nature and only a few causative genes. Animal studies suggest that ACHM may be a good candidate for corrective gene therapy. Future implementation of this therapy in humans requires the presence of viable cone cells in the retina. We investigated the presence of cone cells in ACHM as a function of age. Methods: We evaluated the ...

    6. Retinal nerve fiber layer and future risk of multiple sclerosis.

      BACKGROUND: Optical coherence tomography (OCT)--measured retinal nerve fiber layer (RNFL) values may represent a surrogate biomarker for axonal integrity in multiple sclerosis (MS). The purpose of this study was to determine whether RNFL measurements obtained within two years of an optic neuritis (ON) event distinguish patients at increased risk of developing clinically-definite MS (CDMS). METHODS: Fifty consecutively sampled patients who experienced a single ON event were followed prospectively for ...

    7. Tracking retinal nerve fiber layer loss after optic neuritis: a prospective study using optical coherence tomography

      Introduction Optic neuritis causes retinal nerve fiber layer damage, which can be quantified with optical coherence tomography. Optical coherence tomography may be used to track nerve fiber layer changes and to establish a time-dependent relationship between retinal nerve fiber layer thickness and visual function after optic neuritis. Methods This prospective case series included 78 patients with optic neuritis, who underwent optical coherence tomography and visual testing over a mean period ...
