    2. Endomicroscopy of the human cochlea using a micro-optical coherence tomography catheter

      Endomicroscopy of the human cochlea using a micro-optical coherence tomography catheter
      Sensorineural hearing loss (SNHL) is one of the most profound public health concerns of the modern era, affecting 466 million people today, and projected to affect 900 million by the year 2050. Advances in both diagnostics and therapeutics for SNHL have been impeded by the human cochlea's inaccessibility for in vivo imaging, resulting from its extremely small size, convoluted coiled configuration, fragility, and deep encasement in dense bone. Here ...

      Ophthalmic manifestations of dementing disorders
      Purpose of review Dementia is a term for loss of memory, language, problem-solving, and other thinking abilities, which significantly interferes with daily life. Certain dementing conditions may also affect visual function. The eye is an accessible window to the brain that can provide valuable information for the early diagnosis of people who suffer from Alzheimer's disease, Parkinson's disease , dementia with Lewy bodies as well as from more rare ...

      Wide-field swept-source optical coherence tomography angiography in the assessment of retinal microvasculature and choroidal thickness in patients with myopia
      Background/aims: Pathological myopia (PM) is a leading cause of blindness worldwide. We aimed to evaluate microvascular and chorioretinal changes in different stages of myopia with wide-field (WF) swept-source (SS) optical coherence tomography angiography (OCTA). Methods: This prospective cross-sectional observational study included 186 eyes of 122 patients who had undergone imaging between November 2018 and October 2020. Vessel density (VD) and vessel skeletonised density (VSD) of superficial capillary plexus, deep ...

    5. Inter-device reliability of swept source and spectral domain optical coherence tomography and retinal layer differences in schizophrenia

      Inter-device reliability of swept source and spectral domain optical coherence tomography and retinal layer differences in schizophrenia
      Introduction Optical coherence tomography (OCT) is used to study retinal structure in schizophrenia. Changes in retinal structure, especially the retinal nerve fiber layer (RNFL) has been correlated with psychotic disorders. Measurement variability is a concern since there are various generations of OCT devices. We investigated the inter- and intra-device agreement of macular thickness between spectral domain (SDOCT) and swept sourceOCT (SSOCT), and compared macula and peripapillary group differences in schizophrenia ...

      Structure-Function Mapping Using a Three-Dimensional Neuroretinal Rim Parameter Derived From Spectral Domain Optical Coherence Tomography Volume Scans
      Purpose: To assess the structure-function relationship in glaucoma using Humphrey visual field (HVF) perimetry and a three-dimensional neuroretinal rim parameter derived from spectral domain optical coherence tomography (SD-OCT) volume scans. Methods: Structure-function correlation was analyzed globally and regionally (four quadrants and four sectors).

    7. Watching Death in the Gerbil Cochlea Using Optical Coherence Tomography (OCT)

      Watching Death in the Gerbil Cochlea Using Optical Coherence Tomography (OCT)
      Because it is difficult to directly observe the morphology of the living cochlea, our ability to infer the mechanical functioning of the living ear has been limited. Nearly all of our knowledge about cochlear morphology comes from postmortem tissue that was fixed and processed using procedures that possibly distort the structures and fluid spaces of the organ of Corti. In this study, optical coherence tomography was employed to obtain in ...

    8. Earlier Detection of Glaucoma Progression Using High-Density 3D Spectral-Domain Optical Coherence Tomography Optic Nerve Volume Scans

      Earlier Detection of Glaucoma Progression Using High-Density 3D Spectral-Domain Optical Coherence Tomography Optic Nerve Volume Scans
      Purpose: To compare onset times of glaucoma progression among different glaucoma tests: disc photography (DP), visual field (VF) testing, two-dimensional (2D) retinal nerve fiber layer (RNFL) thickness, and three-dimensional (3D) spectral-domain optical coherence tomography (SD-OCT) neuroretinal rim measurements. Design: Prospective longitudinal cohort study PARTICIPANTS: One hundred and twenty-four eyes of 124 open angle glaucoma patients METHODS: Over a 5-year period, 124 open angle glaucoma patients had yearly DP, VFs, SD-OCT ...

    9. Retinal applications of swept source optical coherence tomography (OCT) and optical coherence tomography angiography (OCTA)

      Retinal applications of swept source optical coherence tomography (OCT) and optical coherence tomography angiography (OCTA)
      The advent of optical coherence tomography (OCT) revolutionized both clinical assessment and research of vitreoretinal conditions. Since then, extraordinary advances have been made in this imaging technology, including the relatively recent development of swept-source OCT (SS-OCT). SS-OCT enables a fast scan rate and utilizes a tunable swept laser at longer wavelengths than conventional spectral-domain devices. These features enable imaging of larger areas with reduced motion artifact, and a better visualization ...

    10. Quantitative evaluation of the human vocal fold extracellular matrix using multiphoton microscopy and optical coherence tomography

      Quantitative evaluation of the human vocal fold extracellular matrix using multiphoton microscopy and optical coherence tomography
      Identifying distinct normal extracellular matrix (ECM) features from pathology is of the upmost clinical importance for laryngeal diagnostics and therapy. Despite remarkable histological contributions, our understanding of the vocal fold (VF) physiology remains murky. The emerging field of non-invasive 3D optical imaging may be well-suited to unravel the complexity of the VF microanatomy. This study focused on characterizing the entire VF ECM in length and depth with optical imaging. A ...

    14. A quantitative comparison of four optical coherence tomography angiography devices in healthy eyes

      A quantitative comparison of four optical coherence tomography angiography devices in healthy eyes
      Purpose Optical coherence tomography angiography (OCT-A) is a novel imaging modality for the diagnosis of chorioretinal diseases. A number of FDA-approved OCT-A devices are currently commercially available, each with unique algorithms and scanning protocols. Although several published studies have compared different combinations of OCT-A machines, there is a lack of agreement on the consistency of measurements across OCT-A devices. Therefore, we conducted a prospective quantitative comparison of four available OCT-A ...

    15. An Artificial Intelligence Approach to Assess Spatial Patterns of Retinal Nerve Fiber Layer Thickness Maps in Glaucoma

      An Artificial Intelligence Approach to Assess Spatial Patterns of Retinal Nerve Fiber Layer Thickness Maps in Glaucoma
      Purpose : The purpose of this study was to classify the spatial patterns of retinal nerve fiber layer thickness (RNFLT) and assess their associations with visual field (VF) loss in glaucoma. Methods : We used paired reliable 24-2 VFs and optical coherence tomography scans of 691 eyes from 691 patients. The RNFLT maps were used to determine the RNFLT patterns (RPs) by non-negative matrix factorization (NMF). The RPs were correlated with mean ...
