Drainage angle is wide but aqueous humor cannot drain due to blockage describes which glaucoma?

• A. Open-angle glaucoma
• B. Closed-angle glaucoma
• C. Presbyopia
• D. Iritis

Answer: (A)

Glaucoma types depend on whether the drainage angle is open and how the outflow of fluid is blocked. When the drainage angle is wide, but the aqueous humor cannot drain due to a blockage in the outflow pathway (often at the trabecular meshwork), this describes open-angle glaucoma. The angle itself is open, allowing potential drainage, but the pathway is impaired, leading to a gradual buildup of pressure. In contrast, closed-angle glaucoma involves a narrow or closed angle, which physically blocks drainage and can cause a rapid rise in pressure. Presbyopia and iritis are not glaucoma forms; presbyopia is age-related lens change affecting near vision, and iritis is inflammation of the iris.
