Nausea and vomiting caused by glaucoma should be actively treated with pressure reduction. Antihypertensive eye drops include Timolol eye drops, Brinzolamide eye drops, and Pilocarpine eye drops. If the effect is not satisfactory, oral administration can also be considered. Common oral medications include Acetazolamide, and systemic use of Mannitol. If necessary, anterior chamber paracentesis can be performed. This series of active treatments can completely control intraocular pressure and relieve symptoms. Eye symptoms mainly include redness, swelling, pain, foreign body sensation, burning sensation, vision decline, headache, nausea, and vomiting. (Please follow the doctor's orders when using medication.)
