Question: 1 / 400

What does angle-closure glaucoma refer to?

A type of glaucoma caused by blocked drainage canals, leading to increased eye pressure

Angle-closure glaucoma specifically refers to a condition where the drainage angle of the eye becomes blocked, often due to the iris being pushed or pulled forward. This blockage prevents aqueous humor from draining out of the eye through the trabecular meshwork, leading to a significant increase in intraocular pressure. This rise in pressure can result in severe pain, nausea, and even permanent vision loss if not treated promptly.

Understanding how angle-closure glaucoma develops is crucial, as it can occur suddenly (acute angle-closure glaucoma) or gradually (chronic angle-closure glaucoma). The name of the condition directly relates to the anatomical angle at which the iris meets the cornea, hence the term "angle-closure." Managing this condition often requires immediate medical intervention to reduce the intraocular pressure and relieve symptoms.
