    6. Macular imaging by optical coherence tomography in the diagnosis and management of glaucoma

      Macular imaging by optical coherence tomography in the diagnosis and management of glaucoma
      The macular area is important to the detection of glaucomatous retinal ganglion cell (RGC) damage. Macular thickness complementary to peripapillary retinal nerve fibre layer (RNFL) thickness can well reflect glaucomatous damage, given that the macula contains more than 50% of the RGCs in a multilayered pattern and larger RGC bodies compared with their axons. Thus, macular ganglion cell thickness parameters recently have been considered to be an effective glaucoma-diagnostic tool ...

    11. Fundus autofluorescence in the buried optic disc drusen: optical coherence tomography findings

      Fundus autofluorescence in the buried optic disc drusen: optical coherence tomography findings
      Optic disc drusen (ODD) is hyaline material within the disc that frequently shows flecks of calcium. 1 Electron microscopic examination revealed that ODD is composed of aggregates of extracellular mitochondria containing calcium crystals. 2 Most diagnostic methods, such as B-scan ultrasonography and computed tomography, focus on the calcification signal. 3 However, calcification is not always detectable, as seen in the buried ODD. 4 Spectral-domain optical coherence tomography (SD-OCT) enables the ...

    Seoul National University is a public research university located in Seoul, Republic of Korea, ranked 50th in the world and 8th in Asia by US News and World Report, and 24th in the world in publications by the Science Citation Index Founded in 1946, Seoul National University was the first national university in South Korea, and served as a model for the many national and public universities in the country. Seoul National University has been recognized for its leading role in Korean academia. 

    Seoul National University Hospital is located in Gumi-dong, Bundang, Seongnam, Gyeonggi-do, South Korea. It began its first treatment on 10 May 2003. It was set up due to a rapid increase in demand for geriatric treatment and the government's request for the establishment of a medical facility for local residents. Seoul National University Bundang Hospital, consists of 6 departments : the Geriatric Medical Centre, Heart Centre, Cranial nerve Centre, Lung Centre, Articulation Centre, and the Health Improvement Centre, and 23 departments, such as Internal Medicine, Surgery, Chest Surgery, Neurosurgery, Orthopaedics, Plastic Surgery, Obstetrics and Gynaecology, and Pediatrics.
