      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 ...

      Early hydroxychloroquine retinopathy: optical coherence tomography abnormalities preceding Humphrey visual field defects
      Background/Aims Hydroxychloroquine (HCQ) retinopathy may result in severe and irreversible vision loss, emphasising the importance of screening and early detection. The purpose of this study is to report the novel finding of early optical coherence tomography (OCT) abnormalities due to HCQ toxicity that may develop in the setting of normal Humphrey visual field (HVF) testing. Methods Data from patients with chronic HCQ exposure was obtained from seven tertiary care ...

      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 ...

      Optical coherence tomography imaging of presumed Cryptococcus neoformans infection localized to the retina
      Purpose To report spectral-domain optical coherence tomography (SD-OCT) findings of presumed Cryptococcus neoformans infection limited to the retina . Methods We report a 39-year-old male with decreased vision for 3 months. Clinical examination revealed multiple cream-colored retinal lesions in the posterior pole of both eyes. SD-OCT demonstrated multiple areas of discrete, hyperreflective deposits in the inner retina, outer retina, and subretinal space without evidence of choroidal involvement. Fundus autofluorescence demonstrated areas ...

      Impact of segmentation density on spectral domain optical coherence tomography assessment in Stargardt disease
      Purpose Automated spectral domain optical coherence tomography (SD-OCT) segmentation algorithms currently do not perform well in segmenting individual intraretinal layers in eyes with Stargardt disease (STGD). We compared selective B-scan segmentation strategies for generating mean retinal layer thickness and preserved area data from SD-OCT scans in patients with STGD1. Methods Forty-five eyes from 40 Stargardt patients were randomly selected from the ongoing Natural History of the Progression of Atrophy Secondary ...

      Volumetric analysis of breast cancer tissues using machine learning and swept-source optical coherence tomography
      In breast cancer, 20%30% of cases require a second surgery because of incomplete excision of malignant tissues. Therefore, to avoid the risk of recurrence, accurate detection of the cancer margin by the clinician or surgeons needs some assistance. In this paper, an automated volumetric analysis of normal and breast cancer tissue is done by a machine learning algorithm to separate them into two classes. The proposed method is based ...

      Purpose : To evaluate the relationship between angle dimensions assessed by gonioscopy or EyeCam and anterior segment optical coherence tomography (AS-OCT). Methods : Subjects aged 50 years or older were recruited from the Chinese American Eye Study (CHES). Each subject underwent a complete ocular exam, including gonioscopy, AS-OCT, and EyeCam. Angle closure was defined as three or more quadrants in which pigmented trabecular meshwork could not be visualized. Angle opening distance (AOD ...

  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.
