Primary Angle Closure Glaucoma: A Review

Abstract

Glaucoma is a leading cause of irreversible blindness worldwide. Primary angle closure glaucoma (PACG), is the second most common form of glaucoma and associated with the closure of the anterior chamber angle. Peripheral anterior synechia (PAS) frequently develop due to an attack of prolonged acute attack or a series subacute attack of angle closure glaucoma. These PAS are usually high and broad and very difficult to find out whether the PAS formed before or during the attack or possibly at both times. Principal management strategy for PACG is about anterior chamber angle by understanding the early stages of appositional angle closure before the PAS. In this review, we describe the current understanding regarding the pathophysiology and treatment of PACG.
