The best way to prevent vision loss from glaucoma is early diagnosis and treatment. See your eyecare practitioner at least every two years for a complete examination, including an IOP check. People at high risk for glaucoma due to high intraocular pressures, family history, ethnic background, age or optic nerve appearance may need more frequent visits to the eye doctor.
A visual field test may be performed on glaucoma suspects to detect peripheral vision loss. It involves staring straight ahead into a machine and clicking a button when you notice a blinking light in your peripheral vision. The visual field test may be repeated at regular intervals for your doctor to determine the extent of vision loss.
Glaucoma treatment (for any form) entails decreasing aqueous humor production, increasing fluid drainage or a combination of the two. These treatments will not restore any vision already lost to glaucoma.
Generally the first stage of glaucoma treatment is beta-blocker eyedrops, which will lower fluid production in the eye. These may not be used in people with heart conditions, because they can affect heart or lung function. There are other pressure-lowering drops besides beta-blockers that are known as alpha-2 agonists and prostaglandin analogs. Many of the drugs used for glaucoma interact with common medications. Patients should discuss these issues with both the family physician and the eyecare practitioner.
Experimental Drug Slows Eye Damage Associated With Glaucoma
Weight Lifting May Increase Risk of Glaucoma
Steroids Illegally Purchased on Internet Cause Glaucoma and Cataracts
Should People With Type 2 Diabetes Be Screened for Glaucoma?
Most cases of glaucoma can be controlled with a single drug or drug combinations, but some patients may require or select surgery. About 70% of patients need new or extra medications within two years after the start of drug treatment. That's compared with 56% of those who choose laser surgery.
During a type of glaucoma surgery called trabeculoplasty, the doctor uses a laser to create tiny holes where the cornea and iris meet, to increase aqueous humor drainage. Another procedure called trabeculectomy creates an artificial drainage area; it's used in cases of advanced glaucoma where there is optic nerve damage and the IOP continues to soar. A third option is a drainage device, which the surgeon implants in your eye to improve fluid drainage.
Glaucoma can be very destructive to your vision; in fact, it's the second-leading cause of blindness in the United States.
Marijuana for Glaucoma: Does It Work?
Some people with glaucoma use marijuana because research has found that it has a small effect in lowering intraocular pressure. However, no research has found that marijuana is anywhere near as effective as legal glaucoma medications, and the American Academy of Ophthalmology, among others, says the risky side effects of marijuana far outweigh any benefit.
Popular opinion persistently exaggerates the benefit of marijuana for glaucoma, which is unfortunate because people who use marijuana instead of their prescribed glaucoma medication run a big risk of losing their vision.

预防青光眼造成视力下降的最有效方法是早诊断早治疗。至少每两年去做一次全面的眼部检查，包括眼内压的检测。而据有青光眼高危因素的人群应更频繁的去做眼部检查，其中高危因素包括高眼内压，家族史，民族因素，年龄，视神经症状。

对疑似青光眼的患者需要做一项视觉测试来确定外周视力减退。实验包括直视实验屏，在视野外周出现闪光点是按下按钮。然后医生规律的进行重复测试来确定视野的范围。

青光眼的治疗侧重于抑制房水的产生和促进房水的吸收或者两者结合。因此这些方法不能恢复青光眼已经造成的视力减退。
