PURPOSE To investigate the distribution of intraocular pressure (IOP) and its associated factors in a large Korean population based on the data from the nationwide cross-sectional survey. METHODS We obtained 2009-2010 data from the Korea National Health and Nutrition Examination Survey (KNHANES) (n = 17 901). After excluding individuals under 19 years of(More)
PURPOSE To investigate peripheral lamina cribrosa depth (PLCD) and its vertical-horizontal difference in eyes with primary open-angle glaucoma (POAG). METHODS Patients with POAG (n=90 eyes) and age-matched healthy individuals (n=90 eyes) underwent swept-source optical coherence tomography (SS-OCT) scans centered at the optic discs. The PLCD was defined as(More)
PURPOSE To evaluate the factors influencing the refractive outcomes of combined phacoemulsification, foldable intraocular lens (IOL) implantation, and pars plana vitrectomy (PPV). SETTING Department of Ophthalmology, Seoul National University Hospital, Seoul, Korea. METHODS One hundred fifty-four consecutive patients who had combined(More)
PURPOSE To compare the relationships between retinal mean sensitivity (MS) and retinal nerve fiber layer (RNFL) thickness, as measured by time-domain (TD) and spectral-domain (SD) optical coherence tomography (OCT). METHODS Recruited subjects were divided into normal, glaucoma suspect, and glaucoma groups. RNFL thickness was measured with TD- and SD-OCT,(More)
PURPOSE To evaluate quantitatively the structural damage of the peripapillary retinal nerve fiber layer (RNFL) in eyes with disc hemorrhage (DH). DESIGN Prospective cross-sectional study. PARTICIPANTS Seventy patients with DH (70 eyes; mean age +/- standard deviation, 60.0+/-11.8 years) and 100 healthy control subjects (100 eyes; mean age +/- standard(More)
PURPOSE To investigate the prevalence, awareness, and risk factors for primary open-angle glaucoma (POAG) in the Korean population. DESIGN The Korea National Health and Nutrition Examination Survey (KNHANES), a population-based cross-sectional study using a complex, stratified, multistage, probability-cluster survey. PARTICIPANTS A total of 13,831(More)
PURPOSE We determined the prevalence of disc hemorrhage (DH) and the associated factors of DH in a large Korean population based on the data from the nationwide cross-sectional survey, the Korea National Health and Nutrition Examination Survey (KNHANES). METHODS We performed a retrospective review of the KNHANES dataset covering January 2012 to December(More)
PURPOSE To investigate the topographic relationship between ganglion cell-inner plexiform layer (GCIPL) and peripapillary retinal nerve fiber layer (pRNFL) defects in open-angle glaucoma patients with localized RNFL defects, using spectral-domain optical coherence tomography (SD-OCT). METHODS We analyzed 140 eyes of 140 patients showing a localized RNFL(More)
PURPOSE The purpose of this study was to evaluate the association between focal lamina cribrosa defect (FLCD) and the topographic characteristics of disc hemorrhage (DH), including area and location. METHODS We enrolled a total of 98 primary open-angle glaucoma eyes with DH (98 subjects). In vivo lamina cribrosa (LC) images were obtained by swept-source(More)
PURPOSE To describe a previously unreported overlapping trajectory of retinal nerve fibers over other retinal nerve fibers in the horizontal plane, and to report on the incidence of this anatomic variation. METHODS This study included 1410 eyes of 1018 subjects with one or more localized retinal nerve fiber layer (RNFL) defects detected by using red-free(More)
