Background: Findings from previous studies on the association between exposure to fine particulate matter (PM) and the risk of infant mortality were inconsistent. Thus, two main objectives of our study were to examine the association between exposure to PM and specified infant mortality and to identify critical trimesters.
Methods: We retrospectively created a birth cohort of singleton full-term infants born in South Korea between 2010 and 2015 using national birth and infant mortality data.
Objectives: Air pollution contributes to mortality and morbidity. We estimated the impact of outdoor air pollution on public health in Seoul metropolitan area, Korea. Attributable cases of morbidity and mortality were estimated.

Methods: The present retrospective cohort study included 127 eyes of 75 patients (PPG, 87; PG, 40) with a mean follow-up of 2.53 years.

Purpose: To investigate the relationship between clinical factors including 24-hour mean ocular perfusion pressure (MOPP, (2/3) x mean arterial pressure [MAP] - intraocular pressure [IOP]) and visual field (VF) progression in eyes with medically treated normal-tension glaucoma (NTG).
Methods: One hundred one eyes of 101 NTG patients followed up for more than 4 years (mean follow-up, 6.2 years +/- 12.
Purpose: To investigate the effect of cataract extraction on the results of frequency doubling technology (FDT) perimetry in healthy subjects.
Design: Single-center, prospective, case series.
Methods: We performed FDT threshold C20-1 and Humphrey Swedish Interactive Threshold Algorithm (SITA)-fast programs within 1 month before and 2 months after phacoemulsification in 52 consecutive nonglaucomatous patients.
Purpose: To evaluate quantitatively the pattern of retinal nerve fiber layer (RNFL) damage in eyes with normal-tension glaucoma (NTG) with hemifield dominant visual field defects using scanning laser polarimetry.
Methods: Prospectively, 40 consecutive eyes from 40 patients with NTG and hemifield defect based on the findings of examination using the Humphrey Field Analyzer underwent RNFL thickness measurements. Twenty normal eyes from 20 subjects matched in age and refractive error formed a control group.
