Meaning and Definition
A serious, acute form of glaucoma where the eye's drainage angle (between iris and cornea) becomes blocked, causing rapid pressure increase and potential vision loss.
A medical emergency characterized by a sudden and painful increase in intraocular pressure, often due to anatomical narrowing or closure of the eye's anterior chamber angle. It is a specific pathological subtype of glaucoma, distinct from the more common open-angle glaucoma.
Dialectal Variation
British vs American Usage
Differences
Spelling and some phrasing. UK English may use 'acute angle-closure glaucoma' more specifically for the sudden attack. US English may refer to it as 'closed-angle glaucoma' more frequently.
Connotations
Identical medical urgency and seriousness in both dialects.
Frequency
Equally low in general discourse, but standard within ophthalmology in both regions.

FAQ
Frequently Asked Questions
No, it is one specific type. The more common form is 'open-angle glaucoma', which develops slowly. Angle-closure glaucoma is often sudden and acute.
Severe eye pain, headache, nausea/vomiting, blurred vision, and seeing rainbow-colored halos around lights are classic symptoms.
An acute attack is an emergency treated with medications to lower eye pressure quickly, often followed by a laser procedure (iridotomy) to create a new drainage pathway.
In some cases, yes. If an eye doctor identifies a 'narrow angle' during a routine exam, a preventive laser iridotomy can be performed to significantly reduce the risk of a future acute attack.

Mnemonic
Imagine a narrow ANGLE in a pipe being suddenly CLOSED by a shutter (iris), causing GLAUcoma (pressure) to build up dangerously behind it.
Conceptual Metaphor
THE EYE IS A PLUMBING SYSTEM: The 'drainage angle' is a pipe; 'closure' is a blockage; 'glaucoma' is the dangerous pressure build-up.
