PURPOSE To evaluate the characteristics and relationship between peripapillary choroidal thickness (pCT), lamina cribrosa thickness (LCT), and peripapillary outer retinal layer thickness (pORT) as determined using spectral domain optical coherence tomography (SD-OCT) enhanced depth imaging (EDI). METHODS In total, 255 participants were included (87(More)
Streptomycin was injected subcutaneously into guinea pigs (n = 12) with unilateral endolymphatic hydrops. In the unoperated ears, sensory cells were degenerated at the basal ends of all cochleas and to varying extents in the vestibular sense organs. Hydropic ears, in contrast, showed greater ototoxicity in the cochlear and saccular sensory cells, while the(More)
Early changes in the vestibular sense organs resulting from the application of a streptomycin sulfate soaked Gelfoam pledget on the fenestra of the lateral semicircular canal were studied by transmission and scanning electron microscopy. Three days after the application, lesions were present in the central part of the lateral crista. The type I sensory(More)
PURPOSE To assess the reproducibility of circumpapillary retinal nerve fiber layer thickness (cRNFLT) and total macular thickness (TMT) parameters using Cirrus spectral domain optical coherence tomography (SD-OCT) and to apply this information to investigate its ability to detect cases where visual field (VF) progression was noted on event-based analysis in(More)
PURPOSE To characterize the circadian pattern of habitual-position intraocular pressure (IOP) and its association with ocular dimension in young myopic patients with open-angle glaucoma (OAG). METHODS A total of 108 young OAG patients with moderate to severe myopia (myopia group) and 67 age-matched OAG patients with emmetropia or mild myopia (control(More)
PURPOSE To quantify long-term changes in anterior segment (AS) parameters after laser peripheral iridotomy (LPI) using AS optical coherence tomography (OCT) in primary angle-closure suspect (PACS). METHODS Thirty-two PACS subjects were imaged at pre-LPI and 2 weeks and 18 months post-LPI using AS OCT. Anterior chamber depth (ACD), iris curvature (IC),(More)
PURPOSE To investigate the relationship between unstable mean ocular perfusion pressure (MOPP) and the rate of paracentral visual field (PVF) progression in patients with medically treated normal-tension glaucoma (NTG). METHODS The data of 157 eyes of 122 patients with NTG who were followed for more than 6 years (mean follow-up, 8.7 years ± 12.6 months)(More)
The aim of this study was to evaluate the incidence of and risk factors for the development of diabetic retinopathy (DR) and progression to proliferative DR (PDR) in Korean patients. Patients diagnosed with type 2 diabetes and followed for more than 5 years at a university-based clinic since 2000 were consecutively enrolled in this retrospective cohort(More)
PURPOSE To investigate the effect of laser peripheral iridotomy (LPI) in subgroups of angle closure eyes based on anterior segment optical coherence tomography (AS OCT)-derived parameters. METHODS Angle closure (primary angle closure [PAC] or PAC glaucoma [PACG]) eyes were imaged using AS OCT before and 2 weeks after LPI. A hierarchical cluster analysis(More)
PURPOSE To investigate the possibility of classifying angle closure eyes in terms of features provided by anterior segment optical coherence tomography (AS OCT). METHODS Angle closure (primary angle closure [PAC] or PAC glaucoma [PACG]) eyes diagnosed by gonioscopy were imaged using AS OCT under the same lighting conditions. Anterior chamber depth (ACD),(More)
