High intraocular pressure (IOP) is usually not self-correcting and requires treatment to control it. High intraocular pressure (IOP) can cause pressure on the optic nerve, which can lead to optic nerve atrophy and vision loss, and is the most important factor contributing to glaucoma. High intraocular pressure usually cannot be cured by itself, so it needs to be treated actively to lower the intraocular pressure and avoid visual function damage. At present, the main ways to control intraocular pressure are through medication, laser treatment and surgery. 1. Medication: The main treatment is to use eye drops for lowering intraocular pressure, commonly used ones are carteolol hydrochloride eye drops, brimonidine tartrate eye drops, and so on. 2. Laser treatment: Peripheral iridostomy treatment and selective laser trabeculoplasty are commonly used laser treatments for lowering intraocular pressure. 3. Surgery: It is usually the last line of defense to reduce intraocular pressure, and commonly used surgical methods include compound trabeculectomy and so on. High intraocular pressure needs to be treated actively, without delaying the treatment, not to mention that it cannot be expected to be cured by itself.
