  • Treat acute angle-closure glaucoma with a combination of medications to reduce aqueous humor production (topical beta blockers, carbonic anhydrase inhibitor, or mannitol if refractory) and medications to increase aqueous humor outflow (topical phenylephrine, pilocarpine, and a topical steroid).
