Medical Benefits  Glaucoma


Glaucoma


Cannabis and Glaucoma

We all know that when we refer to "marijuana" we really mean the dried leaves and tops of the cannabis plant, but not all of us realize that in addition to the chemicals we're accustomed to hearing about - like THC - there are at least 399 other chemical components. This is just one of the reasons cannabis, or more properly, cannabis sativa, has so many medical uses.

One such medical use is in the treatment of glaucoma. Glaucoma is an eye disease that involves increased intraocular pressure that can cause blindness, often by speeding up the growth of cataracts. Cannabis has been shown to reduce the intraocular pressure (IOP) in patients who have POAG, or primary open-angle glaucoma.

Using studies done by the National Eye Institute (NEI) and the Institute of Medicine, as well as on other available information, the Task Force on Complementary Therapies, however, believes that there is no increased benefit or reduced risk that makes marijuana use a more preferred method of treating glaucoma, than any other currently available prescription drugs.

Initial studies completed forty years ago reported that people who smoked pot did have lower IOP for hours after doing so, and research conducted by the NEI also showed that some derivatives of marijuana did result in lowering the IOP when taken orally, intravenously, or via inhalation, but not when applied topically to the eye. The reduced pressure typically lasts for three to four hours, and a side effect - some say a benefit - is a sense of euphoria.

Despite this, there are some adverse effects associated with smoking marijuana, including lowered blood pressure and an increased heart rate. Because some marijuana users in test scenarios have shown reduced blood pressure along with the reduced IOP, researchers as concerned that this may mean blood flow to the optic nerve has been compromised.

At this time, there have been no long-term studies of marijuana as a glaucoma treatment, so most states that allow medical use of marijuana do not include glaucoma as an "allowable condition."

Was diagnosed. The eye drops also only work for a limited amount of time and have some very unpleasant side effects that require other meds to counteract. They caused me to go through a depression, start having asthma like symptoms and caused constip

With the knowledge that the pressure is basically what causes glaucoma then it is only logical to think that something that relaxes will work to aid the problem. If it helps the person to retain their eyesight for even a few days, then it is a good thi

I go to school with an old man who has this. He swears to me that medicating with mmj works better than all other meds.

I lost eyesight in one eye withing a few months of beginning medical treatment so for me to worry about long term effects of cannabis is just ludicrous.
