primary open angle glaucoma

Primary open-angle glaucoma (POAG) is a group of eye diseases characterized by damage to the optic nerve, leading to vision loss. It is a leading cause of vision loss in older adults, typically affecting individuals over 40. The exact cause is unknown but may involve degenerative changes in the eye's fluid drainage channels.

POAG often progresses without early symptoms, with peripheral vision loss occurring before central vision is impacted. While increased intraocular pressure is a risk factor, glaucoma can occur even with normal eye pressure. Treatment focuses on lowering intraocular pressure through eyedrops, medication, laser treatment, or surgery to prevent further vision loss, as lost vision cannot be restored.1
