Is Marijuana an Effective Treatment for Glaucoma? If the effects of cannabis compounds can be isolated, made to be long-acting, and the side effects eliminated, they may lead to new treatments in the future. However, such developments require more research and are years away from becoming a realit.
Currently, the only way to control glaucoma and prevent vision loss is to lower the pressure in your eye. Several current, effective treatments for glaucoma are more reliable and safer than marijuana.
Your ophthalmologist can treat glaucoma with medication, such as prescription eye drops , or surgery , depending on the type of glaucoma and how severe it is. About Foundation Museum of the Eye. By David Turbert , Dan Gudgel. Edited By Anni Delfaro. Cannabis isn't a practical method for treating eye conditions — here's why Glaucoma and other eye conditions cannot be treated with cannabis or other compounds derived from marijuana, such as CBD.
Marijuana could damage the optic nerve in people with glaucoma It's not well understood how cannabis affects eye pressure and glaucoma. Marijuana's history as a purported glaucoma remedy As marijuana has been legalized for medical or recreational use in more U. Could CBD help with glaucoma? It has not yet been possible to formulate a THC eye drop that is capable of introducing a sufficient concentration of the drug into the eye due to its low water solubility of active ingredients.
Topical applications have been associated with irritation and corneal damage. Health Management. Jordyn Imhoff. July 17, AM. The three types of glaucoma are: Open-angle chronic glaucoma Closed-angle acute glaucoma Secondary glaucoma Open-angle glaucoma is a chronic medical condition that is generally painless and although vision threatening, it is a slow or non-progressive disease for which medical and surgical treatments are available.
Marijuana vs. Theresa M. The good and the bad According to Cooney, marijuana can create a 25 percent IOP reduction in 60 to 65 percent of people with or without glaucoma. Other long-term side effects include: Hormonal changes, which can increase the risk of poor pregnancy outcomes Difficulty concentrating Impaired immune system responses Impaired motor coordination Addiction, and withdrawal after cessation of smoking Ocular side effects include: Redness Decreased tear production Double vision Being able to maintain a clear image and focus on distant objects Light sensitivity Eye twitching or spasms of the muscles Tetrahydrocannabinol THC Studies in the last decade have found receptors for active ingredients of marijuana in the tissues of the eyes.
Basic Science and Laboratory Research. Addiction and Substance Abuse. Alternative Medicine. Kellogg Eye Center. All Research Topics. Eye Health. There is a significant variability in potency of THC and other cannabinoids when the plant material is used. There appears to be a dose-response relationship between the amount of marijuana consumed and the degree of IOP reduction, although the length of efficacy does not improve at higher doses.
In one placebo-controlled double-masked study using an oil-based vehicle, no IOP-lowering effect was demonstrated. Both the placebo vehicle and the study drug caused significant ocular irritation.
Although the precise mechanism of action of the drug remains unknown, cannabinoid receptors have been found in the trabecular meshwork, nonpigmented ciliary epithelium, and ciliary muscle of human eyes.
Other cannabinoids may improve aqueous outflow or have neuroprotective effects through inhibition of glutamate release or by blocking glutamate receptors. They may also have antioxidant or vasorelaxive properties. Marijuana use has a significant number of side effects Table 1. Of great concern in glaucoma patients, the drug can cause tachycardia and decreased blood pressure, which can reduce blood flow to an already compromised optic nerve. There has been little research into chronic use of marijuana to treat glaucoma.
One study showed a significant development of tolerance to its ocular hypotensive effects. The cost of this regimen would also greatly exceed the cost of any current glaucoma drug. These limitations in the use of marijuana for the treatment of glaucoma have led major ophthalmic organizations to issue statements opposing the use of marijuana in the treatment of glaucoma.
Glaucoma patients who inquire about use of marijuana should be counseled that, although the drug does lower IOP, there are many limitations to its use in glaucoma, including short duration of action, variable potency, side effects, development of tolerance, and health risks, particularly when smoked. Compared with marijuana, current glaucoma medications more consistently lower IOP with fewer side effects and a longer duration of action.
Patients should be encouraged to continue adherence to prescribed therapy with long-term monitoring of their disease. Marihuana smoking and intraocular pressure. JAMA ; 10 Zielinski G. Activist Robert C.
