    2. AGE challenge: Angle Closure Glaucoma Evaluation in Anterior Segment Optical Coherence Tomography

      AGE challenge: Angle Closure Glaucoma Evaluation in Anterior Segment Optical Coherence Tomography
      Angle closure glaucoma (ACG) is a more aggressive disease than open-angle glaucoma, where the abnormal anatomical structures of the anterior chamber angle (ACA) may cause an elevated intraocular pressure and gradually lead to glaucomatous optic neuropathy and eventually to visual impairment and blindness. Anterior Segment Optical Coherence Tomography (AS-OCT) imaging provides a fast and contactless way to discriminate angle closure from open angle. Although many medical image analysis algorithms have ...

    3. Low Tensor Train- and Low Multilinear Rank Approximationsfor De-speckling and Compression of 3D Optical Coherence Tomography Images

      Low Tensor Train- and Low Multilinear Rank Approximationsfor De-speckling and Compression of 3D Optical Coherence Tomography Images
      This paper proposes low tensor-train (TT) rank and low multilinear (ML) rank approximations for de-speckling and compression of 3D optical coherence tomography (OCT) images for a given compression ratio (CR). To this end, we derive the alternating direction method of multipliers based algorithms for the related problems constrained with the low TT- and low ML rank. Rank constraints are implemented through the Schatten-p (Sp) norm, p e {0, 1/2 ...

    4. Different effect of media opacity on automated and manual measurement of foveal avascular zone of optical coherence tomography angiographies

      Different effect of media opacity on automated and manual measurement of foveal avascular zone of optical coherence tomography angiographies
      Background Optical coherence tomography angiography (OCTA) provides not only visualisation but also quantitative measurement of foveal avascular zone (FAZ). Media opacity is common in elderly subjects with cataracts. This study aimed to investigate the impact of media opacity on automated and manual FAZ measurement. Methods Cirrus 5000 OCTA and Triton OCTA were used to image FAZ using a 33 mm scanning protocol from 30 eyes of 30 healthy normal subjects ...

    5. In vivo assessment of vascular-targeted photodynamic therapy effects on tumor microvasculature using ultrahigh-resolution functional optical coherence tomography

      In vivo assessment of vascular-targeted photodynamic therapy effects on tumor microvasculature using ultrahigh-resolution functional optical coherence tomography
      Abstract Vascular-targeted photodynamic therapy (VTP) is an emerging treatment for tumors. The change of tumor vasculatures, including a newly-formed microvascular, in response to VTP, is a key assessment parameter for optimizing the treatment effect. However, an accurate assessment of vasculature, particularly the microvasculatures changes in vivo , remains challenging due to the limited resolution afforded by existing imaging modalities. In this study, we demonstrated the in vivo imaging of VTP effects ...

    7. Towards multi-center glaucoma OCT image screening with semi-supervised joint structure and function multi-task learning

      Towards multi-center glaucoma OCT image screening with semi-supervised joint structure and function multi-task learning
      Glaucoma is the leading cause of irreversible blindness in the world. Structure and function assessments play an important role in diagnosing glaucoma. Nowadays, Optical Coherence Tomography (OCT) imaging gains increasing popularity in measuring the structural change of eyes. However, few automated methods have been developed based on OCT images to screen glaucoma. In this paper, we are the first to unify the structure analysis and function regression to distinguish glaucoma ...

    11. Longitudinal evaluation of immediate inflammatory responses after intravitreal AAV2 injection in normal rats by optical coherence tomography

      Longitudinal evaluation of immediate inflammatory responses after intravitreal AAV2 injection in normal rats by optical coherence tomography
      Gene therapy has been proposed as a feasible strategy for RGC survival and optic nerve regeneration. Some preclinical and clinical studies revealed intraocular inflammation after intravitreal injection of adeno-associated virus (AAV) by slit-lamp or indirect ophthalmoscope. Here we evaluate the longitudinal profile of immediate inflammatory responses after AAV2 injection in rat retina and vitreous body by optical coherence tomography (OCT). Adult Fischer F344 rats were intravitreally injected once with saline ...

      Repeatability and Agreement of a Swept-Source Optical Coherence Tomography–Based Biometer IOLMaster 700 Versus a Scheimpflug Imaging–Based Biometer AL-Scan in Cataract Patients
      Purpose: To compare the repeatability and agreement between a swept-source biometer and a Scheimpflug biometer in cataract patients. Methods: Three consecutive measurements were obtained using a swept-source biometer (IOLMaster 700) and a Scheimpflug biometer (AL-Scan) in 52 eyes of 52 patients. Keratometry, central corneal thickness (CCT), anterior chamber depth (ACD), axial length , and white-to-white (WTW) distance were recorded. Astigmatism values were transformed into vector components of J0 and J45. Intraoperator ...

      Unifying Structure Analysis and Surrogate-driven Function Regression for Glaucoma OCT Image Screening
      Optical Coherence Tomography (OCT) imaging plays an important role in glaucoma diagnosis in clinical practice. Early detection and timely treatment can prevent glaucoma patients from permanent vision loss. However, only a dearth of automated methods has been developed based on OCT images for glaucoma study. In this paper, we present a novel framework to effectively classify glaucoma OCT images from normal ones. A semi-supervised learning strategy with smoothness assumption is ...

  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.
