The cause of high intraocular pressure may be glaucoma, ocular inflammation, etc. Patients generally can not reduce intraocular pressure through vitamin supplementation, and clinically, the main use of drugs or surgery to reduce intraocular pressure. Commonly used drugs to lower IOP include β-blockers such as carteolol hydrochloride eye drops, carbonic anhydrase inhibitors such as brinzolamide eye drops, and α-agonists such as brimonidine tartrate eye drops. In the case of acute angle-closure glaucoma, Trichostatin nitrate eye drops can be used, and drugs such as metazolamide and mannitol can be used to lower intraocular pressure if necessary. If the effect of drug treatment is not good, patients can also be treated with surgery, such as compound trabeculectomy. It is recommended that patients with elevated intraocular pressure seek medical attention to evaluate their condition and undergo treatment under the guidance of a physician.
