Primary open-angle glaucoma (POAG)

Definition

Primary open-angle glaucoma (POAG) is a chronic eye condition characterized by gradual damage to the optic nerve, often associated with increased intraocular pressure. It is the most common form of glaucoma and can lead to irreversible vision loss if untreated.

5 Must Know Facts For Your Next Test

1. POAG typically progresses slowly and painlessly, making early detection crucial.
2. It is often treated with medications that reduce intraocular pressure, such as prostaglandin analogs and beta-blockers.
3. Risk factors include age, family history, African or Hispanic ancestry, and conditions like diabetes and hypertension.
4. Patients may be asymptomatic in the early stages but experience peripheral vision loss as the disease advances.
5. Regular eye exams are essential for early diagnosis and management of POAG.
