    3. Optical Coherence Tomography Evaluation of Superficial Femoral Artery Directional Atherectomy

      Optical Coherence Tomography Evaluation of Superficial Femoral Artery Directional Atherectomy
      A 70-year-old man presented with lifestyle-limiting intermittent claudication (Rutherford stage III) affecting the right lower extremity. Physical examination of the right lower limb revealed weak distal pulses and a diminished ankle-brachial index of 0.6. Peripheral angiogram showed diffuse 80% stenosis over the right distal superficial femoral artery (SFA). The HawkOne directional atherectomy system (Medtronic Peripheral) was used to restore blood flow by removing plaque. After placing a 7 mm ...

    5. Endometrial Vascularization Characterized by Optical Coherence Tomography and Immunohistochemistry in Women Undergoing In Vitro Fertilization-Embryo Transfer Treatment

      Endometrial Vascularization Characterized by Optical Coherence Tomography and Immunohistochemistry in Women Undergoing In Vitro Fertilization-Embryo Transfer Treatment
      Background and objective: Endometrial angiogenesis is a prerequisite for successful pregnancy. Optical coherence tomography (OCT) is a non-invasive physically optical imaging technique widely used in ophthalmology and cardiology. However, there is no study using OCT to evaluate endometrium. The aim of this study was to use OCT and traditionally histological methods to investigate endometrial vascularization in women undergoing in vitro fertilization-embryo transfer (IVF-ET) treatment and to determine the association with ...

      Spectral Domain-Optical Coherence Tomography Measurements in Alzheimer’s Disease: A Systematic Review and Meta-analysis
      Topic Optical coherence tomography (OCT) is a non-invasive tool to measure specific retinal layers in the eye. The relationship of retinal spectral domain-OCT (SD-OCT) measurements with Alzheimers Disease (AD) and mild cognitive impairment (MCI) remains unclear. Hence, we conducted a systematic review and meta-analysis to examine the SD-OCT measurements in AD and MCI. Clinical Relevance Current methods of diagnosing early AD are expensive and invasive. Retinal measurements of SD-OCT, which ...

      Relationship between Optical Intensity on Optical Coherence Tomography and Retinal Ischemia in Branch Retinal Vein Occlusion
      Branch retinal vein occlusion (BRVO) may be complicated with retinal ischemia in some cases. The purpose of the current study is to investigate the relationship between optical intensity on optical coherence tomography (OCT) and retinal ischemia in BRVO. Twenty-seven eyes diagnosed with BRVO without macular edema were classified into two groups based on the presence or absence of retinal ischemia.

    11. The Role of Optical Coherence Tomography in the Acute Management of Neuro-Ophthalmic Diseases

      The Role of Optical Coherence Tomography in the Acute Management of Neuro-Ophthalmic Diseases
      Optical coherence tomography (OCT) can provide highspeed and high-resolution images of the anatomical structures of the optic nerve head and macula. However, in neuro-ophthalmic conditions that present acutely, structural changes lag functional deficits, and the role of OCT in the acute setting has been challenged. This review aims to summarize the recent literature and evidence supporting the use of OCT in the acute management of some common neuro-ophthalmic scenarios, including ...

    15. Shared-hole graph search with adaptive constraints for 3D optic nerve head optical coherence tomography image segmentation

      Shared-hole graph search with adaptive constraints for 3D optic nerve head optical coherence tomography image segmentation
      Optic nerve head (ONH) is a crucial region for glaucoma detection and tracking based on spectral domain optical coherence tomography (SD-OCT) images. In this region, the existence of a hole structure makes retinal layer segmentation and analysis very challenging. To improve retinal layer segmentation, we propose a 3D method for ONH centered SD-OCT image segmentation, which is based on a modified graph search algorithm with a shared-hole and locally adaptive ...

    16. Optical coherence tomography angiography in glaucoma: a mini-review

      Optical coherence tomography angiography in glaucoma: a mini-review
      The advent of optical coherence tomography angiography (OCT-A) provides a new opportunity to visualize the retinal vasculature in a non-invasive and dye-free manner which may help identify vascular abnormalities in glaucoma. While a reduction in retinal and optic nerve head vessel densities and blood flow indexes measured by OCT-A has been demonstrated in patients with glaucoma in many studies, it is unclear whether OCT-A provides additional information for the detection ...

  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.
