      Picometer scale vibrometry in the human middle ear using a surgical microscope based optical coherence tomography and vibrometry system
      We have developed a highly phase stable optical coherence tomography and vibrometry system that attaches directly to the accessory area of a surgical microscope common to both the otology clinic and operating room. Careful attention to minimizing sources of phase noise has enabled a system capable of measuring vibrations of the middle ear with a sensitivity of 5 pm in an awake human patient. The system is shown to be ...

      Longitudinal Macular Structure-Function Relationships in Glaucoma and Their Sources of Variability
      Purpose 1) Review central structure-function (SF) relationships in glaucoma; 2) compare contributions of within-session and between-session variability to total variability of macular optical coherence tomography (OCT) thickness measurements; and 3) test the hypothesis that longitudinal within-eye variability of central SF relationships is smaller than between-individual variability. Methods We reviewed the pertinent literature on central SF relationships in glaucoma. Thirty-eight eyes (20 normal or glaucoma subjects) had 3 macular images per ...

      Fourier-domain mode-locked laser combined with a master-oscillator power amplifier architecture
      Originally introduced in 2005 for high-speed optical coherence tomography, the rapidly wavelength-swept Fourier-domain mode-locked (FDML) laser still, to this day, enables highest imaging speeds through a very high-speed spectral tuning capability. The FDML laser achieves a tuning bandwidth of over 1/10th of its center wavelength and can sweep this entire bandwidth in less than a microsecond. Interestingly, even though it covers a very broad spectral range, instantaneously it has ...

      Pearls and Pitfalls of Optical Coherence Tomography Angiography Imaging: A Review
      Optical coherence tomography angiography (OCTA) has significantly expanded our knowledge of the ocular vasculature. Furthermore, this imaging modality has been widely adopted to investigate different ocular and systemic diseases. In this review, a discussion of the fundamental principles of OCTA is followed by the application of this imaging modality to study the retinal and choroidal vessels. A proper comprehension of this imaging modality is essential for the interpretation of OCTA ...

      Identification and Characterization of Imaging Technique Errors and Artifacts using Anterior Segment Optical Coherence Tomography for Irido-Corneal Angle Evaluations in Glaucom
      Purpose Anterior segment optical coherence tomography (ASOCT) platforms provide non-invasive and quantifiable evaluations of anterior chamber angle (ACA) anatomy. Even though these ACA measurements have been validated with high repeatability and reproducibility, we are the first study to describe in detail the technique errors and artifacts that may occur during imaging of the ACA. The purpose of this study was to define the different types and quantify the frequency of ...

  4. About UCLA

    UCLA

    University of California at Los Angeles (UCLA) is a public research university located in Westwood, Los Angeles, California, United States. It was founded in 1919, making it the second-oldest general-purpose campus in the University of California system. The name was changed in 1927 to the University of California at Los Angeles. UCLA comprises the College of Letters and Science (the primary undergraduate college) as well as undergraduate colleges Arts and Architecture, Herb Alpert School of Music, Henry Samueli School of Engineering and Applied Science, Nursing, and Theater, Film, and Television, seven professional schools, and five professional Health Science schools. Since 2001, UCLA has enrolled over 33,000 total students annually, and that number is steadily rising.
