Angle Closure in the Namil Study in Central South Korea

Abstract

The overall prevalence of angle closure was 3.2% in the present study. On the basis of these findings, increasing age, shallower ACD, and shorter AL appear to be associated with angle closure. TRIAL REGISTRATION clinicaltrials.gov Identifier: NCT00727168.

Central Corneal Thickness in a Korean Population: The Namil Study

“…[22][23][24] Our study was conducted in compliance with the tenets of the Declaration of Helsinki for the use of human subjects in biomedical research. The study was approved by the Institutional Review Board of Chungnam National University Hospital, and written informed consent was obtained from all participants.…”

“…The details of the Namil Study have been reported previously. [22][23][24] In brief, subject screening was performed between November 2007 and February 2008. Notices addressed to all residents in the Namil-meon area encouraged participation in the study.…”

“…A patient with angle-closure was classified into 1 of 3 clinical subtypes, including primary angle-closure suspect, primary angle-closure, and primary angle-closure glaucoma using the definitions reported by the International Society of Geographical and Epidemiological Ophthalmology as described in a previous study. 23 Subjects were diagnosed with secondary glaucoma or suspected to have glaucoma if they had a history of significant ocular trauma, iridocyclitis, and the presence of new vessels in the iris or chamber angle, or showed other ocular findings that could cause a glaucomatous optic disc or visual field changes.…”

“…22,23 Therefore, eyes with glaucoma or ocular hypertension were excluded from our study. In addition, to minimize the effect of intraocular surgery on CCT, eyes with a history of intraocular surgery or corneal refractive surgery also were excluded.…”

“…The Namil Study was designed to estimate the prevalence of glaucoma and its associated factors in a large population of Korea. [22][23][24] Our study was performed to investigate the distribution of CCT and its association with various ocular and systemic factors in a Korean population, and to compare these results to those of other Asian populations.…”
