Several diseases affect the anterior chamber angle by changing drainage or blocking the meshwork. Primary angle-closure glaucoma occurs when the iris crowds or blocks the angle. Secondary conditions, such as inflammation or neovascularization, can also impair outflow. These issues may raise intraocular pressure and damage the optic nerve.

New abnormal blood vessels can grow across the angle in some conditions. Monitoring and treatment protect against long-term pressure damage.
Yes, both open-angle and angle-closure forms involve drainage problems.
Inflammation may narrow or block the angle.
Tumors inside the eye can distort normal anatomy.
Some changes improve, while others require long-term care.
Primary angle-closure glaucoma occurs when the drainage angle closes, causing a sudden rise in eye pressure. Symptoms include severe eye pain, redness, blurred vision and nausea. It is a medical emergency.
In pigment dispersion syndrome, pigment granules from the iris disperse and clog the trabecular meshwork, potentially causing secondary open-angle glaucoma.
Treatment may include medications to lower intraocular pressure, laser therapy (iridotomy or trabeculoplasty) or surgery. Regular eye exams are key to early diagnosis.
