Angle closure glaucoma occurs when the drainage angle between the iris and cornea becomes blocked, raising eye pressure. An acute attack causes sudden pain, blurred vision, halos, headache, and nausea. Chronic narrow angles can progress quietly and then spike. Quick diagnosis protects the optic nerve from pressure damage.
read more about angle closure glaucoma ...Risk increases with crowded anterior segment anatomy or thick peripheral iris tissue that narrows the drainage pathway.
The anterior chamber angle is formed by the cornea, iris, and the trabecular meshwork at the scleral spur. Its openness influences how aqueous humor exits the eye, shaping pressure dynamics and optical clarity over time.
You should see your eye doctor if you notice sudden or persistent changes in your vision such as blurriness, flashes of light, floaters, or eye pain. Redness, swelling, or discharge that does not improve with basic care also warrants a checkup. Even if symptoms seem mild, getting a professional evaluation can help detect problems early and prevent complications. Regular eye exams are also important to monitor your overall eye health and keep your vision clear.
Acute attacks require urgent pressure lowering with drops, oral medicine, and sometimes IV therapy, followed by laser iridotomy to open a new fluid pathway. Chronic narrow angles are often treated with prophylactic iridotomy. In selected cases, lens extraction or other procedures deepen the angle. Lifelong monitoring guards the optic nerve.
Severe eye pain, sudden blur, halos around lights, headache, and nausea are classic signs of an acute event. Vision may dim quickly. These symptoms are an emergency that needs same day care. Fast treatment can save vision.
Gonioscopy examines the drainage angle directly, while anterior segment OCT and ultrasound biomicroscopy add measurements. Pupil reactions and lens thickness are reviewed. These tests separate narrow but stable angles from eyes at high risk of closure. Findings guide the decision for laser or surgery.
Can both eyes be affected? Yes, fellow eyes often share risks and may need preventive laser.
Will glasses fix it? No, this is an angle anatomy problem.
Is laser painful? Most people tolerate iridotomy well with numbing drops.
