| description | A primary angle-closure glaucoma characterized by acute closure of the anterior chamber angle by an intrinsic defect such that aqueous outflow is blocked and the intraocular pressure becomes suddenly inappropriately elevated threatening optic nerve damage and visual field loss; but that typically resolves spontaneously after several hours, even though it may recur. Interval angle-closure glaucoma has_symptom sudden pain, redness, headache, and blurry vision with haloes around lights that resolves spontaneously. Interval angle-closure glaucoma can be caused by exacerbation of chronic primary angle-closure glaucoma, typically by a medication or state that dilates the eyes and thus narrows the anterior chamber angle, blocking any aqueous outflow. |
