Open-Angle Glaucoma

Open-angle glaucoma is chronic progressive optic neuropathy with an open anterior-chamber angle, producing optic-disc cupping and peripheral field loss, with raised or normal IOP. It is usually asymptomatic until advanced. Treatment: lower IOP with topical hypotensive agents (prostaglandin analogs first-line), selective laser trabeculoplasty, or filtration surgery (trabeculectomy/MIGS) as needed; set target pressure by stage.

Common Symptoms

Asymptomatic until advanced; peripheral field loss; optic-disc cupping; open angle

Causes and Pathogenesis

Trabecular outflow resistance (or IOP-independent susceptibility) causes optic-nerve axonal loss.

Treatment

IOP lowering: topical prostaglandin analogs, SLT, trabeculectomy/MIGS; target by stage

Preventive Measures

Screen IOP/disc/field; family history.

Department to Visit
