title: Clarifying the nomenclature for primary angle-closure glaucoma.
abstract: Despite tremendous development in the field of glaucoma, there is confusion in the nomenclature system for classification, gonioscopy, and mechanisms of primary angle-closure glaucoma. In this article, we critically review the various nomenclature systems and suggest some modifications to the current classifications. These include four diagnostic categories: 1) angle-closure glaucoma suspect; 2) angle-closure hypertension; 3) chronic angle-closure glaucoma; and 4) acute angle-closure glaucoma. Gonioscopy is valuable for evaluating primary angle-closure glaucoma but more precise descriptions of gonioscopic observations are needed. Because of racial differences in the prevalence and mechanisms of primary angle-closure glaucoma, worldwide population-based study is necessary. Newer technologies, such as ultrasound biomicroscopy, show promise for the study of primary angle-closure glaucoma.
