    2. Vitreomacular Interface Disorders in Proliferative Diabetic Retinopathy: An Optical Coherence Tomography Study

      Vitreomacular Interface Disorders in Proliferative Diabetic Retinopathy: An Optical Coherence Tomography Study
      Vitreomacular interface plays an important role in the pathogenesis and progression of proliferative diabetic retinopathy (PDR). This study investigated the prevalence and risk factors of vitreomacular interface disorders (VMID) in PDR. The macular optical coherence tomography (OCT) scans of 493 eyes from 378 PDR patients were retrospectively reviewed to detect VMID, including vitreomacular adhesion (VMA), vitreomacular traction (VMT), epiretinal membrane (ERM), lamellar hole-associated epiretinal proliferation (LHEP), and macular hole (MH ...

    3. Comparing Conventional Grid Laser Photocoagulation and Subthreshold Micropulse Laser in Diabetic Macular Edema Using OCT Angiography

      Comparing Conventional Grid Laser Photocoagulation and Subthreshold Micropulse Laser in Diabetic Macular Edema Using OCT Angiography
      The prevalence of diabetes mellitus has increased significantly in Hong Kong for the past decade [1]. Diabetic macular edema is one of the most common causes of vision loss in patients suffering from diabetes mellitus [3]. Before the introduction of anti-vascular endothelial growth factor agents, laser photocoagulation has been the mainstay treatment for patients with diabetic macular edema. There are two types of laser treatment modalities, namely focal laser, which ...

    4. Direct Estimation of Choroidal Thickness in Optical Coherence Tomography Images with Convolutional Neural Networks

      Direct Estimation of Choroidal Thickness in Optical Coherence Tomography Images with Convolutional Neural Networks
      Automatic and accurate estimation of choroidal thickness plays a very important role in a computer-aided system for eye diseases. One of the most common methods for automatic estimation of choroidal thickness is segmentation-based methods, in which the boundaries of the choroid are first detected from optical coherence tomography (OCT) images. The choroidal thickness is then computed based on the detected boundaries. A shortcoming in the segmentation-based methods is that the ...

    5. Volumetric characterization of microvasculature in ex vivo human brain samples by serial sectioning optical coherence tomography

      Volumetric characterization of microvasculature in ex vivo human brain samples by serial sectioning optical coherence tomography
      Objective: Serial sectioning optical coherence tomography (OCT) enables distortion-free volumetric reconstruction of several cubic centimeters of human brain samples. We aimed to identify anatomical features of the ex vivo human brain, such as intraparenchymal blood vessels and axonal fiber bundles, from the OCT data in 3D, using intrinsic optical contrast. Methods: We developed an automatic processing pipeline to enable characterization of the intraparenchymal microvascular network in human brain samples. Results ...

    7. A multi-regression framework to improve diagnostic ability of optical coherence tomography retinal biomarkers to discriminate mild cognitive impairment and Alzheimer’s disease

      A multi-regression framework to improve diagnostic ability of optical coherence tomography retinal biomarkers to discriminate mild cognitive impairment and Alzheimer’s disease
      Background Diagnostic performance of optical coherence tomography (OCT) to detect Alzheimers disease (AD) and mild cognitive impairment (MCI) remains limited. We assessed whether compensating the circumpapillary retinal nerve fiber layer (cpRNFL) thickness for multiple demographic and anatomical factors as well as the combination of macular layers improves the detection of MCI and AD. Methods This cross-sectional study of 62 AD ( n =92 eyes), 108 MCI ( n =158 eyes), and 55 ...

      Optical coherence tomography angiography metrics predict normal tension glaucoma progression
      Purpose: To prospectively determine the relationship between optical coherence tomography angiography (OCTA) metrics and visual field (VF) progression in eyes with normal tension glaucoma (NTG). Methods: Prospective, cohort study conducted from January 2017 to October 2021. OCTA metrics at the peripapillary region (circumpapillary vessel density (cpVD), vessel diameter index (VDI) and fractal dimension (FD) in the radial superficial capillary network), and the macular region (macular vessel density, foveal avascular zone ...

      Relationship between macular intercapillary area measured by optical coherence tomography angiography and central visual field sensitivity in normal tension glaucoma
      Purpose To investigate the relationship of macular intercapillary area (ICA) with macular ganglion cell-inner plexiform layer (GCIPL) thickness and central visual field sensitivity (CVFS) in normal tension glaucoma (NTG). Methods Seventy-eight early NTG eyes, 33 moderate-to-severe NTG eyes and 75 normal control eyes were cross-sectional evaluated. All participants underwent swept-source optical coherence tomography angiography (OCT-A; DRI-OCT, Topcon, Tokyo, Japan). A customised MATLAB program was used to quantify macular OCT-A metrics ...

    12. Application of Optical Coherence Tomography to a Mouse Model of Retinopathy | Protocol - JoVE

      Application of Optical Coherence Tomography to a Mouse Model of Retinopathy | Protocol - JoVE
      Optical coherence tomography (OCT) offers a noninvasive method for the diagnosis of retinopathy. The OCT machine can capture retinal crosssectional images from which the retinal thickness can be calculated. Although OCT is widely used in clinical practice, its application in basic research is not as prevalent, especially in small animals such as mice. Because of the small size of their eyeballs, it is challenging to conduct fundus imaging examinations in ...

      Purpose: To provide clinical evidence of the associations between retinal neuronal degeneration and microvasculopathy in diabetic retinopathy (DR). Methods: This case-control study included 76 patients (76 eyes) with type 2 diabetes mellitus (DM), and refraction error between -3.0 and +3.0 D.

      Optical Coherence Tomography Classification Systems for Diabetic Macular Edema and Their Associations With Visual Outcome and Treatment Responses
      Optical coherence tomography (OCT) is an invaluable imaging tool in detecting and assessing diabetic macular edema (DME). Over the past decade, there have been different proposed OCT-based classification systems for DME. In this review, we present an update of spectral-domain OCT (SDOCT)-based DME classifications over the past 5 years. In addition, we attempt to summarize the proposed OCT qualitative and quantitative parameters from different classification systems in relation to ...

  2. About The Chinese University of Hong Kong

    The Chinese University of Hong Kong

    The Chinese University of Hong Kong, commonly referred to as CUHK, is the second oldest university in Hong Kong; it is campus-based and also the only collegiate university in the territory. Despite its name, the Chinese University does not conduct its classes solely in Chinese. Both Chinese (Mandarin and Cantonese) and English are languages of instruction.

    The university's founders hoped that it would become the bridge that connects China and the West, and to combine tradition with modernity. The collegiate system CUHK comprises four colleges: Chung Chi College, New Asia College, United College, and Shaw College. All undergraduates are affiliated to one of them. Currently, five new colleges are to be established in the near future; namely Morningside College, S. H. Ho College, C. W. Chu College, Wu Yee Sun College and Lee Woo Sing College.

    Founded in 1963, The Chinese University of Hong Kong (CUHK) is a forward looking comprehensive research university with a global vision and a mission to combine tradition with modernity, and to bring together China and the West. CUHK teachers and students hail from all corners of the world. In 2007, we have more than 5,800 staff members, some 20,000 undergraduate and postgraduate students. Of these students, about 3,000 are from 45 countries and regions outside Hong Kong. The 100,000 alumni are connected through some 80 alumni associations both within and outside Hong Kong.
