Primary Open-Angle Glaucoma

Primary open-angle glaucoma (POAG) is a chronic, progressive optic neuropathy with optic-disc cupping and peripheral visual-field loss, associated with raised or normal intraocular pressure and an open anterior-chamber angle. It is asymptomatic until advanced. Treatment: lower IOP by topical medications (prostaglandin analogs first-line), laser trabeculoplasty, or glaucoma surgery (trabeculectomy/MIGS); target pressure based on stage.

Common Symptoms

Asymptomatic until late; peripheral field loss; optic-disc cupping; open angle on gonioscopy

Causes and Pathogenesis

Reduced trabecular outflow raises IOP (or normal-tension), causing optic-nerve axonal loss.

Treatment

Lower IOP: topical prostaglandin analogs, laser trabeculoplasty, trabeculectomy/MIGS; target by stage

Preventive Measures

Screen IOP/disc/field; family history; IOP lowering.

Department to Visit
