Eyes with angles traditionally described as "occludable" were recorded as primary angle-closure suspects (PACS); eyes with PACS and peripheral anterior synechiae (PAS), or an increased intraocular pressure but without primary angle-closure glaucoma, were recorded as primary angle closure (PAC).<h4>Results</h4>The prevalence of PACS in at least one eye was 5.7% (95% CI 4.72 to 6.62); prevalence increased with age and was more common in women (p<0.001). The prevalence of PAC in at least one eye was 1.50% (95% CI 1.47 to 1.53). All participants with PAS had at least 90 degrees of closure (range 90-360 degrees).<h4>Conclusion</h4>The prevalence of preglaucomatous angle-closure disease (PACS and PAC) in this population was 5.7% and 1.5%, respectively. PACS was more common in women, and its prevalence increased with age.enCopyright © 2007 by the BMJ Publishing Group Ltd.HumansGlaucoma, Angle-ClosureGonioscopyEpidemiologic MethodsSeverity of Illness IndexAge DistributionSex DistributionAdultAgedMiddle AgedRural HealthMyanmarFemaleMaleJournal article002007117510.1136/bjo.2006.1086880002473477000062-s2.0-3434734281848575Casson, R.
