PURPOSE Vascular endothelial cell growth factor (VEGF) is strongly induced by oxidative stress in retinal pigment epithelial (RPE) cells, and VEGF-A is a survival factor for various cell types. This study was conducted to determine whether the autocrine VEGF signaling pathway in RPE cells is involved in the mechanism of adaptive response to oxidative(More)
READ WITH INTEREST THE ARTICLE BY SONG AND ASSOiates reporting axial length measurements in a large opulation. I noted that the authors do not describe hether their axial length measurements by A-scan ltrasound were performed using the applanation (conact) technique or the immersion technique. Because his is important information for the reader, it should(More)
OBJECTIVE To report the initial experiences with the 25-gauge transconjunctival sutureless vitrectomy (TSV) system, including intraoperative and postoperative problems. METHODS We retrospectively reviewed the medical records and surgical videotapes of 50 consecutive patients who underwent vitrectomy performed by one surgeon using the TSV system. RESULTS(More)
To determine the incidence, demographic features, and clinical characteristics of polypoidal choroidal vasculopathy (PCV) in Korean patients. A retrospective review was undertaken of 392 eyes of 321 symptomatic patients suspected of having exudative age-related macular degeneration (AMD) after their first visit to a tertiary hospital between February 2002(More)
To report a case of cytomegalovirus (CMV) retinitis after intravitreal injection of triamcinolone acetonide (IVTA). A 77-year-old woman with macular edema due to central retinal vein occlusion (CRVO) developed peripheral retinitis 4 months after IVTA. A diagnostic anterior chamber paracentesis was performed to obtain DNA for a polymerase chain reaction(More)
PURPOSE To describe the pathoanatomy of diabetic macular edema in optical coherence tomography and its correlation with fluorescein angiography patterns. METHODS Sixty eyes of 56 patients were analyzed. Diabetic macular edema was classified into typical focal leakage (from microaneurysm), typical diffuse leakage (the capillary plexus), or(More)
PURPOSE To describe the morphologic features of ischemic diabetic maculopathy by high-resolution optical coherence tomography (OCT) and their correlation with the damaged foveal avascular zone (FAZ) on fluorescein angiography (FA). DESIGN Observational case series. PARTICIPANTS One hundred twenty-four eyes of 63 patients with diabetic retinopathy and(More)
OBJECTIVE The aim of this study was to identify the short-term effect, safety, and durability of intravitreally injected bevacizumab in patients with macular edema (ME) caused by retinal vein obstruction (RVO) and diabetic macular edema (DME). METHODS We retrospectively evaluated 39 eyes of 36 patients, 14 with ME caused by RVO and 25 with DME, who(More)
To compare autofluorescence (AF) findings using wide-field (Optomap) and conventional (HRA-AF) confocal scanning laser ophthalmoscopy (cSLO) systems in patients with central serous chorioretinopathy (CSC), and to investigate the correlations between AF findings and functional and anatomical status. Optical coherence tomography (OCT) and AF images were(More)
