Currently, the medications used in the treatment of glaucoma can be divided into two categories: topical medications and systemic medications, and the commonly used medications are carteolol hydrochloride eye drops, mannitol injection and so on. Topical drugs are mainly eye drops to lower intraocular pressure, which can stabilize the patient’s intraocular pressure for a longer period of time and have relatively minor side effects. Commonly used drugs include carteolol hydrochloride eye drops, brimonidine tartrate eye drops, brinzolamide eye drops, latanoprost eye drops, and so on. Systemic medication is usually used to rapidly reduce intraocular pressure for a short period of time, to relieve the patient’s eye swelling and pain and other uncomfortable symptoms, commonly used drugs are mannitol injection, vinpocetine tablets, acetazolamide tablets, etc., but can not be used for a long period of time, long-term use of the patient’s renal function will be adversely affected. Glaucoma patients need to consult the ophthalmology department in the hospital, under the guidance of the doctor to use reasonable drug treatment.
