an·gle-·clo·sure glau·co·ma

primary glaucoma in which contact of the iris with the peripheral cornea excludes aqueous humor from the trabecular drainage meshwork.

closed-angle glaucoma

Glaucoma caused by a shallow anterior chamber and thus a narrow filtration angle through which the aqueous humor normally passes. Because the rate of movement of the aqueous humor is impaired, intraocular pressure increases. In general, headache, haloes around single sources of light, blurred vision, and eye pain are symptomatic.
