      OCT retinal nerve fiber layer thickness differentiates acute optic neuritis from MOG antibody-associated disease and Multiple Sclerosis
      Background: Optic neuritis (ON) is the most common manifestation of myelin oligodendrocyte glycoprotein antibody associated disorder (MOGAD) and multiple sclerosis (MS). Acute ON in MOGAD is thought to be associated with more severe optic disk edema than in other demyelinating diseases, but this has not been quantitatively confirmed. The goal of this study was to determine whether optical coherence tomography (OCT) can distinguish acute ON in MOGAD from MS, and ...

      Longitudinal Assessment of Ellipsoid Zone Recovery using En Face Optical Coherence Tomography after Retinal Detachment Repair
      Purpose Suboptimal functional outcomes following rhegmatogenous retinal detachment (RRD) repair may be related to photoreceptor abnormalities including alterations of the ellipsoid zone (EZ) which may not be apparent on cross-sectional optical coherence tomography (OCT). This study assessed EZ recovery using en face OCT following RRD repair and its association with visual acuity. Design Post hoc analysis of a randomized controlled trial.

      Semi-Automated Extraction of Lens Fragments Via a Surgical Robot Using Semantic Segmentation of OCT Images With Deep Learning - Experimental Results in Ex Vivo Animal Model
      The overarching goal of this work is to demonstrate the feasibility of using optical coherence tomography (OCT) to guide a robotic system to extract lens fragments from ex vivo pig eyes. A convolutional neural network (CNN) was developed to semantically segment four intraocular structures (lens material, capsule, cornea, and iris) from OCT images. The neural network was trained on images from ten pig eyes, validated on images from eight different ...

      Diagnostic Accuracy of Endobronchial Optical Coherence Tomography for the Microscopic Diagnosis of Usual Interstitial Pneumonia
      Rationale: Early, accurate diagnosis of interstitial lung disease (ILD) informs prognosis and therapy, especially in idiopathic pulmonary fibrosis (IPF). Current diagnostic methods are imperfect. HRCT resolution is limited while surgical lung biopsy (SLB) carries risks of morbidity/mortality. Endobronchial optical coherence tomography (EB-OCT) is a low-risk, bronchoscope-compatible modality that images large lung volumes in vivo with microscopic resolution, including subpleural lung, and has the potential to improve the diagnostic accuracy ...

      Deep learning improves image reconstruction in optical coherence tomography using less data
      Optical coherence tomography (OCT) is a non-invasive imaging method that can provide 3D information of biological samples. The first generation of OCT systems were based on time-domain imaging, using a mechanical scanning set-up. However, the relatively slow data acquisition speed of these earlier time-domain OCT systems partially limited their use for imaging live specimen. The introduction of the spectral-domain OCT techniques with higher sensitivity has contributed to a dramatic increase ...

  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.
