    3. Fluorescein angiography and optical coherence tomography concordance for choroidal neovascularisation in multifocal choroidtis

      Fluorescein angiography and optical coherence tomography concordance for choroidal neovascularisation in multifocal choroidtis

      Purpose To compare the utility of fluorescein angiography (FA) and optical coherence tomography (OCT) as diagnostic adjuncts in evaluating symptomatic patients with choroidal neovascularisation (CNV) due to multifocal choroiditis (MFC). Methods Patients with CNV due to MFC were retrospectively evaluated in a consecutive fashion. Fundus photography, FA, OCT and biomicroscopy were used to establish the diagnosis. Primary outcome measures included CNV classification (type 1 or occult and type 2 or classic) location and the associated FA and OCT findings. Results Twenty eyes from 17 patients were included in the study. In 19 eyes (95%) the FA revealed CNV type 2 ...

    4. High-Resolution Photoacoustic Imaging of Ocular Tissues

      High-Resolution Photoacoustic Imaging of Ocular Tissues
      Abstract: Optical coherence tomography (OCT) and ultrasound (US) are methods widely used for diagnostic imaging of the eye. These techniques detect discontinuities in optical refractive index and acoustic impedance, respectively. Because these both relate to variations in tissue density or composition, OCT and US images share a qualitatively similar appearance. In photoacoustic imaging (PAI), short light pulses are directed at tissues, pressure is generated due to a rapid energy deposition in the tissue volume and thermoelastic expansion results in generation of broadband US. PAI thus depicts optical absorption, which is independent of the tissue characteristics imaged by OCT or US ...

    5. The Supercontinuum Laser Source: Fundamentals with Updated References (Book)

      The Supercontinuum Laser Source: Fundamentals with Updated References (Book)
      Photonics and nonlinear optics are important areas of science, engineering and technology. One of the most important ultrafast nonlinear optical processes is the supercontinuum (SC) – the production of intense white light pulses covering: uv, visible, NIR, MIR, and IR. It is produced using ultrashort laser pulses (ps/fs) to produce the ultrabroad band of frequencies. This book covers the fundamental principles and surveys research of current thinkers and experts in the field with updated references of the key breakthroughs over the past decade and a half. The application of SC are time-resolved pump-SC probe absorption and excitation spectroscopy for chemistry ...

    6. Assessment of Scleral Spur Visibility With Anterior Segment Optical Coherence Tomography

      Purpose: To develop a grading system to evaluate the scleral spur visibility and to investigate the association between this and the angle width. Methods: Sixty healthy normal subjects (33 with open angles and 27 with narrow angles on dark room gonioscopy) underwent anterior segment imaging with the Visante OCT (Carl Zeiss Meditec, Dublin, CA). The anterior chamber angles at 12-o' clock hour positions were imaged and analyzed. The scleral spur at each clock hour position was independently graded by 2 observers. A scleral spur visibility score (SSVS) of 2 denotes clear visibility of the scleral spur. SSVS of 0 and ...

    7. Imaging systems and methods to improve backscattering imaging using circular polarization memory

      An optical technique to improve the imaging of a target inside suspensions of scattering particles includes the illumination of the scattering particles with circularly polarized light. The backscattered light from the host medium preserves the helicity of incident light, while the backscattered light reflected from the target is predominated with light of opposite helicity. Based on the observed helicity difference in the emerging light that originated at the target and that backscattered from the medium, the present optical technique improves the image contrast using circular polarization. This approach makes use of polarization memory which leads to the reflected light from ...

  2. About City University of New York

    City University of New York

    City University of New York is the public university system of New York City. It is the largest urban university in the United States. More than 450,000 degree-credit, adult, continuing and professional education students are enrolled at campuses located in all five New York City boroughs. CUNY is the third-largest university system, in terms of enrollment, in the United States, behind the State University of New York (SUNY) and California State University systems. CUNY and SUNY are separate and independent university systems, although both are public institutions which receive funding from New York State.  City College of New York is part of CUNY.
