Over 3 million people in the United States suffer from glaucoma. Globally, this number rises to well over 60 million people. But the question is, what is glaucoma? It is an eye condition which leads to the damaging of the optic nerve and if left untreated, could lead to permanent blindness.
Though the surgical solutions for treating glaucoma have considerably improved in recent years, cutting glaucoma-related blindness cases by half, the number of topical drugs you can use to treat the condition has not increased. A lot of people have, as a result, turned to medical marijuana to treat glaucoma.
The benefits cannabinoids present when it comes to treating glaucoma can be dated back to the 70s. Ever since then, people have used cannabis to treat glaucoma since it provides pain relieving effects and lowers intraocular pressure.
At first, when the benefits of smoking cannabidiol were tested, the results were good. However, the issue with smoking CBD was that the relief and benefits were short-term.
After a while, the topical application of cannabidiol eye drops was considered to be a viable option for addressing glaucoma, providing effective pain relief. Ever since cannabidiol eye drops have been used for inflammation during early to mid-stage glaucoma.
How Does CBD Influence Glaucoma?
Ever since the 70s, it’s been known that cannabis can lower intraocular pressure associated with glaucoma.
However, during the early stages of research, cannabidiol was only smoked or used as edible oils. Recent studies, however, show that applying CBD directly to the eye may be quite beneficial when it comes to the treatment of neuropathic ocular pain.
Cannabis contains a variety of cannabinoids including cannabidiol, which is a non-intoxicating compound.
Some studies have shown that combining THC and CBD together produce a different experience than soley one or the other. The interesting thing is that over the last 40 years, there’s been evidence suggesting that cannabidiol alone, in the form of topical eye drops, could of major help when it comes to the management of glaucoma.
In a 1979 study published in the International Journal of Biopharmacology and Pharmacology, the effects and benefits of cannabidiol were studied on 16 patients suffering from glaucoma.
After taking CBD, tests revealed that their blood pressure has reduced and their heart rates increased. Their intraocular pressure, the main cause for glaucoma, also decreased.
How Do Cannabidiol Eye Drops Work?
Most studies and research had come to the conclusion that cannabidiol decreases intraocular pressure when topically applied, helping alleviate and treat glaucoma symptoms.
The benefits of cannabidiol eye drops have been considered from many studies and researches since the mid-70s; however, it worth noting that the use of CBD eye drops has had a couple of hiccups.
Using cannabidiol extracts has been quite challenging, especially when applied topically since they have a lipophilic profile, which means that cannabis oil formulations mix well with oil.
As such, of all cannabidiol compounds in a single dose, only 5% reaches the target when used as topical eye drops. That is why the development of cannabidiol eye drops slowed down a bit.
A couple of solutions were tested in an effort to circumvent this problem. One solution was using light mineral oils. Small amounts of the compound THC were dissolved in this oil before being applied onto the eye.
Though this considerably decreased intraocular pressure, which was one of the desired effects, THC-infused mineral oil irritated the eyes.
However, in recent times, it has been found that cyclic sugar molecules can be a viable solution. These formulations were found to lower intraocular pressure, and test results were mostly successful. Scientists are still working on new CBD eye drops researches and studies.
What Research Says About Cannabidiol Eye Drops?
CBD eye drops related studies and research have been conducted since the 70s. For example, a study conducted by the Dalhousie University in Halifax, Canada, showed that cannabidiol was effective at relieving pain.
Another study published in 1979 in the International Journal of Biopharmacology and Pharmacology provided information on the effects of cannabidiol on 16 patients. All the study patients had decreased blood pressure, increased heart rates and reduced intraocular pressure behind their eyes.
Another study concluded in 2006 by Tomida, showed that cannabidiol doses higher than 40 mg could increase intraocular pressure instead of relieving it.
In most cases, glaucoma patients believed that dose of 10 to 20 mg would have been most effective and useful.
Does Cannabidiol Lower Eye Pressure?
Tons of research has shown that cannabidiol does lower eye pressure by up to 25 to 30%.
However, when topically applied, only 5% of the active compounds reach their destination. Because of this, a lot of patients rely on other medical cannabis products such as CBD eye drops and marijuana.
Most people prefer vaping cannabidiol or using it as edible oil to reap the most benefits.
The Benefits of Cannabidiol Eye Drops
It is believed that CBD oil can offer tons of benefits ranging from decreasing depression and anxiety to pain relief. So, it’s no wonder that cannabidiol has also been used to make CBD eye drops to help treat glaucoma by reducing IOP and relieving pain.
Cannabidiol Eye Drops for Glaucoma
As of this moment, there’s no permanent cure for the eye condition. However, tons of studies have found that cannabis compounds, CBD and THC, are quite effective when it comes to treating glaucoma.
For example, in open-angle glaucoma, a condition that affects over 95% of people suffering from glaucoma, intraocular pressure increases right behind the eye and cannabidiol can help relieve it. Furthermore, an earlier study, one of the first ones conducted on relieving glaucoma symptoms, especially intraocular pressure using CBD, showed that the substance was capable of reducing the pressure by 25-30%.
However, there was a problem; the benefits only lasted a couple of hours, which meant that users would have to consume cannabis several times a day to enjoy its pain relieving and intraocular pressure benefits.
Soon after, more studies were conducted to learn how the topical application of cannabidiol would work. The idea was this, applying cannabidiol drops directly into the eye would be a great way to avoid the adverse side effects and reactions of continuous CBD use.
However, since CBD eye drops had a lipophilic profile, only 5% of beneficial properties in the compound got to their target. So cannabidiol eye drops are still work in progress, but researchers and doctors do agree on the benefits they have to offer.
Cannabidiol Eye Drops for Pain
The eye’s cornea has numerous sensory nerve endings, which make it very sensitive to chemicals, temperature, and touch. The slightest contact with the cornea will usually result in involuntary reflexes that make you blink.
Injuries to the cornea often come with neuropathic pain, that is usually related to damaged pain receptors and nerve terminals. Researchers have been studying various options for managing neuropathic pain, including cannabinoid treatments.
Cannabinoids attach themselves to cannabinoid receptors that are localized in parts of our brain and skin related to pain transmission. These cannabinoids activate these receptors, reducing inflammation.
It is a well-known fact that medical weed alleviates most pain.
And that’s why so many people suffering from severe illnesses like cancer, multiple sclerosis, epilepsy, Alzheimer’s diseases, post-traumatic stress disorder, back pain, and so on, opt to use CBD products and medical marijuana to treat symptoms.
Cannabis oil has also been used to treat glaucoma �” but most people prefer vaping CBD or using it as edible oils to relieve intraocular pressure and pain.
Where to Buy Cannabidiol Eye Drops?
Researchers and doctors are still looking for the best formula to make CBD eye drops since coming up with a formula that allows cannabidiol oil to be topically applied and even offer the most effective results has been quite challenging.
While finding information about cannabidiol eye drops online isn’t a problem, it is vital that you first consult your doctor and check with your local laws before ordering any.
Your doctor should be able to advise you on whether the formula used in the cannabidiol eye drop you get is effective or not, and if it could interfere the current eye medications, you are taking.
Proper Use and Dosage?
We recommend starting with a dose which your doctor says you should take. Many people often begin with a small amount to figure out how the application of the cannabinoids effect your body when absorbed through your eyes.
The problem with smoking cannabis to treat glaucoma has been the fact that smoking THC and CBD rich cannabis may cause irritation in your eyes due to the ignition of the plant, above a live flame.
Cannabis infused eye drops may be the solution to reducing the irritation we may feel during the rough, difficult time of a disease or pain which just won’t go away no matter how hard we try to feel better.
Are Cannabidiol Drops Right For You?
If you are suffering from glaucoma, then this study done on optical pain is a study you should read over.
The evidence points toward positive results when being used to reduce pain caused by glaucoma.
