Open-angle glaucoma

Definition

Open-angle glaucoma is a chronic eye condition characterized by progressive damage to the optic nerve due to increased intraocular pressure. It is the most common form of glaucoma and can lead to vision loss if untreated.

5 Must Know Facts For Your Next Test

1. Open-angle glaucoma often has no symptoms in its early stages, making regular eye exams crucial for early detection.
2. Intraocular pressure (IOP) management is central to treating open-angle glaucoma, often involving medications like prostaglandin analogs and beta-blockers.
3. Prostaglandin analogs increase the outflow of aqueous humor, thereby reducing IOP.
4. Beta-blockers decrease the production of aqueous humor, also lowering IOP.
5. Untreated open-angle glaucoma can lead to irreversible vision loss and blindness.
