J Ophthalmic Vis Res. 2024 Mar 14;19(1):88-108. doi: 10.18502/jovr.v19i1.15443. eCollection 2024 Jan-Mar.

Abstract

Glaucoma is the leading cause of irreversible blindness worldwide. Among all glaucoma types, primary angle closure glaucoma (PACG) affects approximately 23 million people worldwide, and is responsible for 50% of glaucoma-related blindness, highlighting the devastating consequences of this disease. The main mechanism of PACG is relative pupillary block. High-risk populations are female gender, Asian ethnicity, high hyperopia, short axial length, and a thick/anteriorly positioned lens. This review discusses the clinical diagnosis, classification, and management of patients with a narrow angle with and without intraocular pressure (IOP) elevation and glaucomatous optic nerve damage, including laser peripheral iridotomy (LPI), endocycloplasty (ECPL), lens extraction, and goniosynechialysis.

Keywords: Laser Peripheral Iridotomy; Lens Extraction; Narrow Angle; Glaucoma; Gonioscopy.
