Acute Persistent Visual Loss: Acute Angle-Closure Glaucoma
What causes it?
Blockage of the aqueous outflow channels by the iris can send intraocular pressure up suddenly and produce a cloudly cornea, severe aching eye, and brow pain.
What to do?
Try to lower intraocular pressure by instilling topical pilocarpine 2% every five minutes for three doses, topical timolol 0.5% one dose, and acetazolamide 500 mg one dose by mouth of vein. Then refer promptly to an ophthalmologist.
