acute angle closure glaucoma

Angle closure glaucoma Ophthalmology An abrupt block in the fluid circulation in the eye, resulting in ↑ intraocular/anterior chamber pressure and potential damage of the optic nerve and blindness which occurs when the intensity of iris bombé is sufficient to occlude the anterior chamber angle–ACA; AACG is more common in Pts with preexisting narrowing of the ACA, which occurs in hypermetropes Clinical Sudden onset of blurred vision, severe ocular or facial pain, halos, N&V, ↑ intraocular pressure, shallow anterior chamber, steamy cornea, fixed–nonreactive dilated pupil, ciliary injection Management IV/oral acetazolamide, topical beta blockers, hyperosmotic agents, pilocarpine or intraocular pressure; after intraocular pressure is ↓, peripheral iridectomy to establish a permanent communication between anterior and posterior chambers; if there is no response to medical management, emergency trabeculectomy, laser sclerostomy.
