The distribution of the intercell interference (ICI) in conventional cellular networks employing orthogonal frequency-division multiple-access (OFDMA) with quadrature-amplitude modulation (QAM) tends to approach a Gaussian distribution when all available subcarriers in each cell are fully loaded. Recently, it has been also shown that the worst-case(More)
PURPOSE To evaluate the efficacy and safety of reduced-fluence photodynamic therapy (PDT) combined with bevacizumab for polypoidal choroidal vasculopathy (PCV). DESIGN Prospective, noncomparative, interventional case series. METHODS Sixteen treatment-naïve patients with polypoidal choroidal vasculopathy were treated with reduced-fluence PDT combined(More)
PurposeThe purpose of this study is to determine the efficacy of half-fluence photodynamic therapy (PDT) depending on the degree of hyperfluorescence based on indocyanine green angiography (ICGA) for treatment of chronic central serous chorioretinopathy (CSC).MethodsWe conducted a prospective study of 30 eyes of 30 patients with chronic CSC. Half-fluence(More)
Age-related macular degeneration (AMD) is a major cause of blindness, but presents differently in Europeans and Asians. Here, we perform a genome-wide and exome-wide association study on 2,119 patients with exudative AMD and 5,691 controls, with independent replication in 4,226 patients and 10,289 controls, all of East Asian descent, as part of The Genetics(More)
PURPOSE To evaluate the association of the lysyl oxidase-like 1 (LOXL1) single nucleotide polymorphisms (SNPs) in the Korean population with exfoliation syndrome (XFS) and to investigate the association between the SNPs and phenotypes of XFS. METHODS Eighty-nine unrelated patients with XFS and 146 unrelated control subjects were recruited. LOXL1 SNPs,(More)
We analyze the performance of bit interleaved coded modulation (BICM) and coded modulation (CM) systems with frequency and quadrature amplitude modulation (FQAM), which is a combination of frequency shift keying (FSK) and quadrature amplitude modulation (QAM). Numerical results show that for modest code rates in low signal-to-noise ratio regions, the(More)
PURPOSE To establish the extent of the peripheral retinal vasculature in normal eyes using ultra-widefield (UWF) fluorescein angiography. DESIGN Prospective, observational study. PARTICIPANTS Fifty-nine eyes of 31 normal subjects, stratified by age, with no evidence of ocular disease in either eye by history and ophthalmoscopic examination. METHODS(More)
BACKGROUND AND OBJECTIVE To study the relationship between baseline morphologic characteristics of the choroidal neovascular (CNV) lesion and long-term development of macular atrophy in eyes with neovascular age-related macular degeneration (AMD) treated with ranibizumab (Lucentis; Genentech, South San Francisco, CA). PATIENTS AND METHODS Certified(More)
AIM To evaluate the efficacy and safety of active removal of silicone oil with low and high viscosity through a 23-gauge transconjunctival cannula using an external vacuum pump. METHODS This study was conducted as a prospective, interventional case series. A total of 22 eyes of 21 patients [1000 centistokes (cSt): 17 eyes, 5700 cSt: 5 eyes] were included(More)
BACKGROUND/AIMS To compare the short-term efficacy of intravitreal aflibercept treatment according to the subtypes of polypoidal choroidal vasculopathy (PCV) based on indocyanine green angiography (ICGA). METHODS Twenty-nine patients (29 eyes) with treatment-naïve subfoveal PCV were consecutively enrolled in this institutional study. The subjects were(More)
