    2. Automated Retinal Vein Cannulation on Silicone Phantoms using Optical Coherence Tomography-Guided Robotic Manipulations

      Automated Retinal Vein Cannulation on Silicone Phantoms using Optical Coherence Tomography-Guided Robotic Manipulations
      Retinal vein occlusion is one of the most common causes of vision loss, occurring when a blood clot or other obstruction occludes a retinal vein. A potential remedy for retinal vein occlusion is retinal vein cannulation, a surgical procedure that involves infusing the occluded vein with a fibrinolytic drug to restore blood flow through the vascular lumen. This work presents an image-guided robotic system capable of performing fully automated cannulation ...

      Deliberations of an International Panel of Experts on OCTA Nomenclature of nAMD
      A panel of imaging experts was assembled to review neovascular age-related macular degeneration optical coherence tomography angiography descriptors published to date, and test agreement on use of these terms, which was found to be low. Optical coherence tomography angiography (OCTA) has been used to identify and characterize macular neovascularization (MNV) secondary to age-related macular degeneration (AMD). 1-4 Many studies have explored OCTA morphological features of MNV that might serve as ...

      Macular Surgery Current Practice and Trends (Textbook)
      Recent technological advances in the diagnosis of macular disorders have enhanced our understanding of these diseases. At the same time, advances in small-gauge vitrectomy instrumentation and techniques have improved the safety and efficiency of surgery, allowing macular conditions that would have otherwise resulted in blindness to be treated effectively, preserving patients sight. Macular surgery continues to evolve rapidly, thanks to exciting future technology trends. This book provides a detailed and ...

      In Vivo Cochlear imaging provides a tool to study endolymphatic hydrops
      Exposure to noise trauma, such as that from improvised explosive devices, can lead to sensorineural hearing loss and a reduced quality of life. In order to elucidate the mechanisms underlying noise-induced hearing loss, we have adapted optical coherence tomography (OCT) for real-time cochlear visua lization in live mice after blast exposure. We demonstrated that endolymphatic hydrops develops following blast injury, and that this phenomenon may be associated with glutamate excitotoxicity ...

      Cohort profile: a collaborative multicentre study of retinal optical coherence tomography in 539 patients with neuromyelitis optica spectrum disorders
      Purpose Optical coherence tomography (OCT) captures retinal damage in neuromyelitis optica spectrum disorders (NMOSD). Previous studies investigating OCT in NMOSD have been limited by the rareness and heterogeneity of the disease. The goal of this study was to establish an image repository platform, which will facilitate neuroimaging studies in NMOSD. Here we summarise the profile of the Collaborative OCT in NMOSD repository as the initial effort in establishing this platform ...

      Evaluation of the inner choroid using OCT angiography
      The advent of optical coherence tomography angiography (OCTA) has allowed a qualitative and quantitative analysis of the retinal vasculature and the choriocapillaris. With the use of OCTA, several studies evaluated the changes in the choriocapillaris showing how this vascular structure plays a significant role in the pathogenesis of different conditions. This article reviews the current methods of analysis of the choriocapillaris and the relevant findings in different chorioretinal diseases.

      Classification of advanced and early stages of diabetic retinopathy from non-diabetic subjects by an ordinary least squares modeling method applied to OCTA images
      As the prevalence of diabetic retinopathy (DR) continues to rise, there is a need to develop computer-aided screening methods. The current study reports and validates an ordinary least squares (OLS) method to model optical coherence tomography angiography (OCTA) images and derive OLS parameters for classifying proliferative DR (PDR) and no/mild non-proliferative DR (NPDR) from non-diabetic subjects. OLS parameters were correlated with vessel metrics quantified from OCTA images and were ...

  2. 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.
