What Is Primary Open Angle Glaucoma (POAG)? - All About Vision
2020年7月23日 · Primary open-angle glaucoma (POAG) is the most common type of glaucoma. It usually occurs when pressure within the eye has slowly gotten higher and higher over time. If eye pressure rises too much, it can damage the optic nerve and lead to permanent vision loss. When glaucoma is called “primary,” it means it doesn’t have an identifiable cause.
