    2. An anomaly detection approach for the identification of DME patients using spectral domain optical coherence tomography images

      An anomaly detection approach for the identification of DME patients using spectral domain optical coherence tomography images
      This paper proposes a method for automatic classification of spectral domain OCT data for the identification of patients with retinal diseases such as Diabetic Macular Edema (DME). We address this issue as an anomaly detection problem and propose a method that not only allows the classification of the OCT volume, but also allows the identification of the individual diseased B-scans inside the volume. Our approach is based on modeling the ...

    5. Advances of optical coherence tomography in myopia and pathologic myopia

      Advances of optical coherence tomography in myopia and pathologic myopia
      The natural course of high-axial myopia is variable and the development of pathologic myopia is not fully understood. Advancements in optical coherence tomography (OCT) technology have revealed peculiar intraocular structures in highly myopic eyes and unprecedented pathologies that cause visual impairment. New OCT findings include posterior precortical vitreous pocket and precursor stages of posterior vitreous detachment; peripapillary intrachoroidal cavitation; morphological patterns of scleral inner curvature and dome-shaped macula. Swept source ...

    8. Retinal Imaging Techniques for Diabetic Retinopathy Screening

      Retinal Imaging Techniques for Diabetic Retinopathy Screening
      Due to the increasing prevalence of diabetes mellitus, demand for diabetic retinopathy (DR) screening platforms is steeply increasing. Early detection and treatment of DR are key public health interventions that can greatly reduce the likelihood of vision loss. Current DR screening programs typically employ retinal fundus photography, which relies on skilled readers for manual DR assessment. However, this is labor-intensive and suffers from inconsistency across sites. Hence, there has been ...

    10. Longitudinal Evaluation of Cornea With Swept-Source Optical Coherence Tomography and Scheimpflug Imaging Before and After Lasik

      Longitudinal Evaluation of Cornea With Swept-Source Optical Coherence Tomography and Scheimpflug Imaging Before and After Lasik
      Abstract: Swept-source optical coherence tomography (OCT) is the latest advancement in anterior segment imaging. There are limited data regarding its performance after laser in situ keratomileusis (LASIK). We compared the reliability of swept-source OCT and Scheimpflug imaging for evaluation of corneal parameters in refractive surgery candidates with myopia or myopic astigmatism. Three consecutive measurements were obtained preoperatively and 1 year postoperatively using swept-source OCT and Scheimpflug imaging. The study parameters ...

    11. Prediction of spontaneous closure of traumatic macular hole with spectral domain optical coherence tomography

      Prediction of spontaneous closure of traumatic macular hole with spectral domain optical coherence tomography
      It has been known that some traumatic macular holes can close spontaneously. However, knowledge about the types of macular hole that can close spontaneously is limited. In this retrospective study, we investigated patients with traumatic macular hole who were followed-up for at least 6 months without any surgical intervention. Clinical data and spectral domain optical coherence tomography (SD-OCT) images were compared between groups with and without macular hole closure. Overall ...

  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.
