Angle-closure glaucoma, also known as closed-angle glaucoma or narrow-angle glaucoma, is a type of glaucoma characterized by the blockage of the drainage angle within the eye, leading to increased intraocular pressure (IOP). Here's a breakdown to help you understand it:
Anatomy of the Eye:
The eye contains a clear fluid called aqueous humor, which is continuously produced by the ciliary body and circulates within the eye to maintain its shape and nourish the surrounding tissues.
Aqueous humor drains out of the eye through a drainage system located in the angle formed between the iris (colored part of the eye) and the cornea (clear outer layer of the eye). This drainage angle allows fluid to exit the eye and maintain normal intraocular pressure.
Pathophysiology of Angle-Closure Glaucoma:
In angle-closure glaucoma, the drainage angle becomes blocked or narrowed, preventing the normal outflow of aqueous humor from the eye.
This blockage can occur suddenly (acute angle-closure glaucoma) or gradually over time (chronic angle-closure glaucoma).
When the drainage angle is blocked, aqueous humor cannot exit the eye efficiently, leading to a rapid increase in intraocular pressure.
Elevated intraocular pressure can compress the optic nerve, which transmits visual signals from the eye to the brain, causing damage over time and potentially leading to vision loss if left untreated.
Risk Factors:
Angle-closure glaucoma is more common in individuals with certain anatomical predispositions, such as a shallow anterior chamber (the space between the cornea and iris) or a narrow drainage angle.
Other risk factors include age (older adults are at higher risk), family history of glaucoma, certain ethnicities (such as East Asian descent), and certain medical conditions (such as hyperopia or farsightedness).

Symptoms:
Acute angle-closure glaucoma can present with sudden, severe eye pain, blurred vision, halos around lights, redness of the eye, headache, nausea, and vomiting. These symptoms require immediate medical attention.
Chronic angle-closure glaucoma may present with milder symptoms or be asymptomatic until vision loss occurs gradually over time.
Diagnosis:
Diagnosis of angle-closure glaucoma typically involves a comprehensive eye examination, including measurement of intraocular pressure, examination of the drainage angle using gonioscopy, assessment of optic nerve damage, and visual field testing.
Treatment:
Treatment of angle-closure glaucoma aims to reduce intraocular pressure to prevent further optic nerve damage and preserve vision. Treatment options may include medications (eye drops), laser procedures (such as laser peripheral iridotomy or iridoplasty), and in some cases, surgery (such as trabeculectomy or lens extraction).
Early detection and prompt treatment are essential for managing angle-closure glaucoma and preserving vision. Individuals at risk should undergo regular eye examinations to monitor for signs of glaucoma and receive appropriate treatment if necessary.
