The difference between open-angle and closed-angle glaucoma depends on which of these two drainage pathways is damaged. In open-angle glaucoma, the trabecular meshwork offers increased...
Open-angle glaucoma is the most common type in the United States, where 9 in 10 people with glaucoma have the open-angle type. Many people don’t have any symptoms until they start to lose their vision, and people may not notice vision loss right away.
There are two main types of glaucoma: open-angle glaucoma (OAG) and closed-angle glaucoma (CAG). In OAG, the drainage angle in the eye remains open. In CAG, the drainage angle...
This can damage the optic nerve. With regular eye exams, Open-Angle Glaucoma may be found early and usually responds well to treatment to preserve vision. Angle-Closure Glaucoma. The other main type of glaucoma is Primary Angle-Closure Glaucoma, also called Narrow-Angle Glaucoma.
Open-angle glaucoma. This is the most common form of glaucoma. The drainage angle formed by the iris and cornea remains open. But other parts of the drainage system don't drain properly. This may lead to a slow, gradual increase in eye pressure. Acute angle-closure glaucoma. This form of glaucoma happens when the iris bulges.
Open-Angle vs. Closed-Angle Glaucoma. Glaucoma results from the drainage angle becoming blocked or clogged. This slows down the flow of eye fluid and increases eye pressure. With primary open-angle glaucoma, the trabecular meshwork (spongy tissue in the drainage angle) slowly becomes clogged.
Learn about the key differences between closed-angle glaucoma and open-angle glaucoma, two common types of glaucoma. Understand the symptoms, causes, and treatment options for each condition.
The collection of glaucomatous diseases is subdivided into open-angle and closed-angle glaucoma, both of which can have primary or secondary causes and can be of an iatrogenic or non-iatrogenic origin (see Image. Classification of Open-Angle Glaucoma).

Open-angle glaucoma is characterized by an anatomically open angle but with an obstructed and slowed drainage system outflow. The mechanism of blockage is unclear. An increase in intraocular pressure results, characterized by retinal ganglion cell damage, then peripheral vision loss in early disease and central vision loss in late disease. [1]
