There are two main ways to control the lowering of intraocular pressure in patients with glaucoma: first, through the action of drugs; second, through the way of surgery. For the control of intraocular pressure of drugs currently on the market there are five main: the first, the most classic hairy fruit rutaecarpine, by narrowing the pupil to reduce intraocular pressure. The second, beta-blockers, are more commonly used clinically as carteolol or timolol. The third, adrenergic agonists, are more commonly used, including brimonidine tartrate. The fourth, carbonic anhydrase inhibitors, is mainly used is vinpocetine. The fifth, prostaglandin-like drugs, more commonly used travoprost or latanoprost. Each of these five types of medications lowers IOP by different mechanisms, and all of them are available in the form of eye drops, except for the carbonic anhydrase inhibitors, which are taken orally. IOP can also be lowered surgically, and there are two main types of surgical mechanisms: first, surgery to disrupt the structure of aqueous humor production, mainly with ciliary photocoagulation or ultrasound coagulation. In the second category, surgery to improve the function of the aqueous drainage channels or to create new artificial aqueous humor channels, the most important surgical procedures in this category include anguloplasty or implantation of drainage valves and pins, as well as filtration surgery.
