PURPOSE To assess the relationship between serum level of 25-hydroxyvitamin D (25(OH)D) and refractive error in Korean adolescents. METHODS A total of 2038 adolescent aged 13 to 18 years, who participated in the Korea National Health and Nutrition Examination Survey (KNHANES) from 2008 to 2011 underwent refractive examination using an autorefractor. Serum(More)
PURPOSE The main objective of this study is to determine the anti-inflammatory effect of topical amniotic membrane (AM) suspension on corneal alkali burn compared to topical serum eyedrops. METHODS Thirty eyes from 30 Sprague-Dawley male rats were used. After alkali injuries using 1 N NaOH, the control group (n = 10) received topical PBS four times a day(More)
PURPOSE Allergic conjunctivitis (AC) from an allergen-driven T helper 2 (Th2) response is characterized by conjunctival eosinophilic infiltration. Because curcumin has shown anti-allergic activity in an asthma and contact dermatitis laboratory models, we examined whether administration of curcumin could affect the severity of AC and modify the immune(More)
PURPOSE To investigate the biochemical mechanism of amniotic membrane (AM) suspension on corneal wound healing, particularly on epithelial proliferation and migration. METHODS Human corneal epithelial cells (HCECs) were cultured in media with different concentrations of AM suspension (5% and 30%), Dulbecco's Modified Eagle Medium: Nutrient Mixture F-12(More)
PURPOSE To investigate the longitudinal changes in corneal topographic indices over time in patients with mild keratoconus (KC) and to determine predictive factors for the increase in corneal curvature. METHODS The authors retrospectively reviewed the data of 94 eyes of patients with mild KC who had undergone computerized videokeratography (Orbscan IIz;(More)
BACKGROUND AND OBJECTIVES Multipotent mesenchymal stem cells (MSCs) represent a promising cell-based therapy for a number of degenerative conditions. Understanding the effect of aging on MSCs is crucial for both autologous therapy development and allogenic donors in older subjects whom degenerative diseases typically afflict. In this study, we investigated(More)
PURPOSE To investigate the efficacy of umbilical cord serum eyedrops for the treatment of neurotrophic keratitis. DESIGN Prospective noncomparative case series. PARTICIPANTS Twenty-eight eyes of 28 patients with neurotrophic keratitis who were refractory to conventional treatment. METHODS The patients with neurotrophic keraitis were treated with 20%(More)
BACKGROUND To investigate the distribution of intraocular pressure (IOP) and refractive errors according to age group in a representative sample of non-glaucomatous Korean adults. METHODS A total of 7,277 adults (≥ 19 years) who participated in the Korea National Health and Nutrition Examination Survey (KNHANES) from 2008 to 2011 underwent ophthalmic(More)
PURPOSE We evaluated various preoperative anterior segment parameters measured with a Pentacam rotating Scheimpflug camera and compared them with those of conventional methods. We also evaluated the effect of different parameters on corneal endothelial cells after cataract surgery. METHODS Pentacam examination was performed in 88 eyes from 88 patients to(More)
PURPOSE To evaluate retinal nerve fiber layer (RNFL) thickness profiles according to the foveal position relative to the optic disc in myopia METHODS In 164 eyes of 164 healthy myopic subjects, the disc-foveal angle was defined as the angle between a horizontal line through the disc center and the line connecting the fovea and disc center in fundus(More)
