Angle-closure
A form of glaucoma in which the angle between the iris and the cornea inside the eye is closed, stopping drainage of the aqueous humor fluid and producing pressure that compresses and damages the optic nerve. Angle-closure glaucoma occurs in two forms, acute and chronic. The acute version can be a painful attack requiring emergency treatment. The chronic version occurs over time, producing no recognizable symptoms.
