    2. Characteristics of Earlier Versus Delayed Presentation of Very Late Drug‐Eluting Stent Thrombosis: An Optical Coherence Tomographic Study

      Characteristics of Earlier Versus Delayed Presentation of Very Late Drug‐Eluting Stent Thrombosis: An Optical Coherence Tomographic Study
      Background The pathophysiology underlying very late drug‐eluting stent ( DES ) thrombosis is not sufficiently understood. Using optical coherence tomography, we investigated characteristics of very late stent thrombosis ( VLST ) according to different onset times. Methods and Results A total of 98 patients from 10 South Korean hospitals who underwent optical coherence tomography for evaluation of very late DES thrombosis were retrospectively included in analyses. VLST occurred at a median of 55 ...

    3. Factors Associated With Visual Field Progression in Cirrus Optical Coherence Tomography-guided Progression Analysis: A Topographic Approach

      Factors Associated With Visual Field Progression in Cirrus Optical Coherence Tomography-guided Progression Analysis: A Topographic Approach
      Purpose: To identify factors associated with visual field (VF) progression in optical coherence tomography (OCT)-guided progression analysis (GPA) using a topographic approach. Methods: Topographic components of OCT-GPA maps (Cirrus HD-OCT; Carl Zeiss Meditec) were classified according to location (temporal, superotemporal, superonasal, nasal, inferornasal, and inferotemporal), size (small, medium, and large), shape (wedge and irregular types), and pattern of retinal nerve fiber layer (RNFL) progression (widening, deepening, and new development ...

      Alterations of the Foveal Avascular Zone Measured by Optical Coherence Tomography Angiography in Glaucoma Patients With Central Visual Field Defects
      Purpose : To investigate whether the area and shape of the foveal avascular zone (FAZ) as assessed by optical coherence tomography angiography (OCTA) are altered in glaucomatous eyes with central visual field defects (CVFDs). Methods : A total of 78 patients with open-angle glaucoma with central or peripheral visual field defects (PVFDs) confined to a single hemifield were studied retrospectively. Foveal avascular zone area and circularity were measured using OCTA images from ...

    5. A Case of Wyburn-Mason Syndrome with Facial Nevus Flammeus and the Associated Optical Coherence Tomography Findings

      A Case of Wyburn-Mason Syndrome with Facial Nevus Flammeus and the Associated Optical Coherence Tomography Findings
      Purpose To describe a case of Wyburn-Mason Syndrome, which is a rare phakomatosis, and its associated optical coherence tomography findings. Case summary A 5-year-old boy was referred to our clinic for decreased vision in his right eye. He had nevus flammeus on his right forehead, upper eyelid, and cheek. His best corrected visual acuity was hand motion in the right eye, in which a relative afferent pupillary defect was noted ...

    6. Recanalization of Organized Thrombi Demonstrated by Coronary CT Angiography Compared With OCT

      Recanalization of Organized Thrombi Demonstrated by Coronary CT Angiography Compared With OCT
      Recanalization of organized thrombi (ROT) is a rarely recognized disease histologically characterized by older coronary thrombi forming small lumens or endothelium-lined neovascular channels within thrombus. Optical coherence tomography (OCT) is the method of choice for diagnosis and shows signal-rich, high backscattered septa dividing the lumen into multiple small channels that communicate with each other (1) . Computed tomography angiography (CTA) in the longitudinal and cross-sectional planes may demonstrate the ROT by ...

    7. Incidence and Clinical Significance of Poststent Optical Coherence Tomography Findings: One-Year Follow-Up Study From a Multicenter Registry

      Incidence and Clinical Significance of Poststent Optical Coherence Tomography Findings: One-Year Follow-Up Study From a Multicenter Registry
      Background Optical coherence tomography (OCT) was recently introduced to optimize percutaneous coronary intervention. However, the exact incidence and significance of poststent OCT findings are unknown. Methods and Results A total of 900 lesions treated with 1001 stents in 786 patients who had postprocedure OCT imaging were analyzed to evaluate the incidence of poststent OCT findings and to identify the OCT predictors for device-oriented clinical end points, including cardiac death, target ...

      Purpose : To evaluate the value of lamina cribrosa (LC)-related parameters assessed by optical coherence tomography (OCT) in the future prediction of glaucomatous progression. Methods : Glaucoma or glaucoma suspect eyes were followed up for more than 2 years. Glaucoma progression was defined by optic disc/retinal nerve fiber layer (RNFL) photographic assessment or serial visual field exams. LC thickness, anterior LC distance (ALD) and prelaminar tissue thicknesses were determined with ...

      Comparison of Neoatherosclerosis and Neovascularization Between Patients With and Without Diabetes : An Optical Coherence Tomography Study
      Objectives This study aimed to investigate the characteristics of neoatherosclerosis (NA) in patients with diabetes mellitus (DM) after drug-eluting stent (DES) implantation using optical coherence tomography. Background NA is an important substrate for stent failure. In vivo NA characteristics in DM patients have not been investigated. Methods A total of 397 patients with 452 DES who underwent follow-up optical coherence tomography examination after DES implantation were enrolled. Characteristics of NA ...

    12. A Hierarchical Cluster Analysis of Normal-Tension Glaucoma Using Spectral-Domain Optical Coherence Tomography Parameters

      A Hierarchical Cluster Analysis of Normal-Tension Glaucoma Using Spectral-Domain Optical Coherence Tomography Parameters
      Purpose: Normal-tension glaucoma (NTG) is a heterogenous disease, and there is still controversy about subclassifications of this disorder. On the basis of spectral-domain optical coherence tomography (SD-OCT), we subdivided NTG with hierarchical cluster analysis using optic nerve head (ONH) parameters and retinal nerve fiber layer (RNFL) thicknesses. Patients and Methods: A total of 200 eyes of 200 NTG patients between March 2011 and June 2012 underwent SD-OCT scans to measure ...

  2. About Asan Medical Center

    Asan Medical Center

    Asan Medical Center Korea’s largest tertiary referral hospital with 2,189 beds, was founded in 1989 by the late Chairman Chung_Ju-yung of Asan Foundation, with the philanthropic principles of meeting the growing demand for specialized treatments to the under privileged in society. Since then, this patient-oriented hospital has been caring more than 8,300 outpatients, 2,080 inpatients, and 180 emergency patients, while successfully performing 195 complex surgical operations on a daily basis. When AMC opens a 20-story new building in 2008, this hospital will be equipped with 3,000 beds and could offer upgraded health care services.
