Air pollution is an important public health concern and the ocular surface continuously exposed to pollutants in outdoor air. Ocular abnormalities related air are thought be a subtype of dry eye disease (DED). However, date, there no large-scale study evaluating association between DED that includes multiple pollutants.To investigate associations Korean population.A population-based cross-sectional using data on 16 824 participants fifth Korea National Health Nutrition Examination Survey was...
Although previous studies have suggested that meteorological factors and air pollutants can cause dry eye disease (DED), few clinical cohort determined the individual combined effects of these on DED. We investigated (humidity temperature) [particles with a diameter ≤ 2.5 $$\upmu$$ m (PM2.5), ozone (O3), nitrogen dioxide (NO2), carbon monoxide (CO)] A retrospective study was conducted 53 DED patients. evaluated by Symptom Assessment in Dry Eye (SANDE), tear secretion, film break-up time...
Outdoor Air Pollution and Pterygium in KoreaWe investigated relationships between outdoor air pollution pterygium Korean adults.This study includes 23,276 adults population-based cross-sectional data using the Korea National Health Nutrition Examination Survey 2008-2011.Pterygium was assessed slit lamp biomicroscopy.Air (humidity, particulate matter with aerodynamic diameter less than 10 μm [PM10], ozone [O3], nitrogen dioxide [NO2], sulfur levels [SO2]) for 2 years preceding ocular...
To compare the short-term therapeutic effects of topical corticosteroids in patients with refractory dry eye disease (DED) according to tear matrix metalloproteinase 9 (MMP-9) point-of-care positivity.This study was conducted on 137 who were referred from other clinics, complaining irresponsive DED or acute flares despite routine treatment cyclosporin diquafosol. The received for 1 month. evaluated by SANDE (Symptom Assessment Dry Eye) questionnaire, film breakup time, ocular surface...
To investigate the effects of humidity and temperature on dry eye disease (DED).A retrospective, clinic-based study was conducted DED patients undergoing treatment. Patients were followed up at least twice, symptoms signs evaluated using Symptoms Assessment Questionnaire in Dry Eye (SANDE) score, tear secretion, film breakup time (TBUT), ocular staining osmolarity. Mean values for 1 week before examinations used as environmental exposure level. The relationship between temperature, with...
Abstract Background To evaluate the effects of pretreatment for dry eye disease (DED) on accuracy intraocular lens (IOL) power calculation. Methods Patients who underwent uneventful cataract surgery were included in study. IOL was determined using SRK/T and Barrett Universal II (Barrett) formulas. The patients divided into non-pretreatment groups, those group treated with topical 0.5% loteprednol etabonate 0.05% cyclosporin A 2 weeks prior to surgery. Ocular biometry performed all groups...
Abstract The Korean Intermittent Exotropia Multicenter Study (KIEMS) was a retrospective, cross-sectional and multicenter study for the investigation of intermittent exotropia involved 65 strabismus specialists from 53 institutions in Korea. Purpose this to present ophthalmologic findings KIEMS. Consecutive patients with ≥ 8 prism diopters (PD) at distance or near fixation were included. Best-corrected visual acuity, cycloplegic refraction data, angles deviation several cardinal positions,...
Purpose: To investigate changes in the clinical features of patients with dry eye disease (DED) according to short-term outdoor ground-level ozone exposure. Methods: This prospective observational study included DED who were treated same topical drugs (0.05% cyclosporine or 3% diquafosol) and visited hospital twice at 2-month intervals. Patients showed a short tear film breakup time positive ocular surface staining assigned diquafosol groups, respectively. The index (OSDI) score, secretion,...
<i>Purpose:</i> To compare the effect of volumes used in sub- Tenon’s anesthesia on efficacy and intraocular pressure (IOP) vitreoretinal surgery. <i>Methods:</i> A prospective clinical trial was conducted patients undergoing sub-Tenon’s for Patients were randomized to receive either 3-, 5- or 7-ml anesthetic solution. IOP measured immediately prior injection, after injection at 2, 5 10 min injection. Pain scores assigned using a numerical visual analogue scale...
To evaluate the efficacy and safety of a pars plana Ahmed valve implantation combined with 23-gauge sutureless vitrectomy in treatment patients medically uncontrolled neovascular glaucoma (NVG) proliferative diabetic retinopathy (PDR).The authors retrospectively reviewed records 11 consecutive refractory NVG PDR who underwent placement an implant. Control intraocular pressure (IOP), pre- postoperative best-corrected visual acuity development intra- complications were evaluated during...
To investigate the relationship between myopic progression and intermittent exotropia, impact of surgery for exotropia on in early school-aged children (from 7 years to 12 age).Medical records patients with myopia were reviewed. Patients divided into three groups; (A) at presentation who underwent bilateral lateral rectus muscle recession when 7-12 old; (B) merely observed exotropia; (C) straight ocular alignment. Main outcome measurements simple rate per year, preoperative postoperative...
Purpose: Aging is a major risk factor in dry eye disease (DED), and understanding sexual differences very important biomedical research. However, there little information about sex the effect of aging on DED. We investigated other factors for Methods: This study included data 16,824 adults from Korea National Health Nutrition Examination Survey (2010–2012), which population-based cross-sectional survey. DED was defined as presence frequent ocular dryness or previous diagnosis by an...
Inferior oblique (IO) myectomy can result in self-adjustment; the greater preoperative hyperdeviation, larger postoperative correction. This study estimated effect of IO recession primary position and contralateral gaze.Records 43 patients with muscle overaction associated congenital unilateral superior palsy were reviewed retrospectively. Seventeen who had a 10-mm (IO attached at 2 mm temporal 3 posterior from inferior rectus insertion) 26 standard 14-mm evaluated months postoperatively....
To evaluate the effects of early surgical intervention in infantile exotropia on motor and sensory functions, we reviewed records 17 subjects diagnosed with before age 12 months, receiving surgery 24 a follow-up period greater than one year, between 1996 2000. Of (6 intermittent, 11 constant), 14 (82%) 8 constant) had final horizontal deviation <10 PD, 3 (18%) needing re-operation. Fusion gross binocularity were developed 7 (4 5 subjects, respectively. Seven stereopsis 200 seconds or better,...
Purpose: To report a case of endogenous endophthalmitis due to Aeromonas hydrophila in patient with distal common bile duct carcinoma and biliary sepsis.Methods: A 72-year-old woman carcinoma, obstructive jaundice, diabetes mellitus, hypertension had 1-day history blurred vision, redness, eye discharges the right eye.An ophthalmic examination showed no light perception increased intraocular pressure, severe corneal edema, anterior chamber reaction, exudative membranes on lens surface,...
