CBD Eye Drops: The Highlights

  • The benefits of cannabinoids in treating glaucoma date back to the 1970s. Ever since then, cannabis has been used to treat glaucoma, because it lowers intraocular pressure and provides pain relieving effects.
  • The benefits of CBD eye drops have been deemed clear from many types of research and studies since the mid-1970s, however, the use of the drops has had a few hiccups.
  • Studies and research relating to cannabis eye drops have been done going back to the 1970s.
  • CBD eye drops are still a work in progress though doctors and researchers have agreed upon its potential benefits.
  • The recommended dosage of CBD eye drop, according to some studies, should be between 10 to 20 mg CBD.

What Are CBD Eye Drops?

Ever since the 1970s, it has been known that cannabis lowers intraocular pressure that is associated with glaucoma.

However, in the early studies, CBD was smoked and used as edible oils.  Recently, studies have shown that applying cannabidiol (or CBD for short) directly onto the eye might be beneficial for treating neuropathic ocular pain.

Marijuana includes many different kinds of cannabinoids, of which CBD is one of the non-intoxicating compounds.

Some researches have shown that cannabidiol may be as beneficial as THC and other similar compounds that cause psychoactive effects. Interestingly, over the past 40 years, there has been evidence that suggests that CBD alone in the form on CBD eye drops could help in glaucoma treatment.

In a study that was published in the International Journal of Pharmacology and Biopharmacology already in 1979, the benefits and effects of CBD were analyzed on 16 different patients, who were suffering from glaucoma.

After the patients had taken CBD, their blood pressure reduced and heart rate increased. Also, the intraocular pressure, which is the direct cause for glaucoma, decreased.

How CBD Eye Drops Work

Many types of research and studies have concluded that CBD decreases intraocular pressure when applied topically, which helps alleviate and treat symptoms of glaucoma.

Using CBD extracts has been challenging when applied topically, because of their lipophilic profile. This means, that the cannabis oil formulations don’t easily mix with water.

Thus, of all the CBD compounds in one dose, only 5 percent reach its target when used as CBD eye drops. This is why the development of CBD eye drops stalled for a while.

A few different solutions were tested to overcome this problem. The solutions involved using light mineral oil. Small amounts of THC were dissolved in the oil and then applied directly onto the eye.

Though this resulted in the desired effect of decreased intraocular pressure, the THC infused mineral oil was irritating to the human eyes.

However, recently cyclic sugar molecules have proven to be a solution. These formulations did lower the intraocular pressure and the results were successful. Researchers are still working on new studies and researches when it comes to CBD eye drops.

What the Research Says about CBD Eye Drops

Researches and studies relating to CBD eye drops have been concluded ever since the 1970s. For instance, the researchers concluded in Halifax, Canada, in Dalhousie University, states that CBD is effective in relieving pain.

Also, a study published in the International Journal of Pharmacology and Biopharmacology in 1979 had tested the effects of CBD on 16 patients. They all had experienced a decrease in blood pressure and increase in heart rate, in addition to decreased intraocular pressure behind the eyes.

Another study that was concluded in 2006 by Tomida et al., found that CBD doses that are higher than 40 milligrams can increase intraocular pressure in the eye instead of relieving it.

In many cases, glaucoma patients thought doses of 10-20 milligrams to have been most useful and effective.

Does CBD Lower Eye Pressure?

Many types of research have shown that CBD lowers eye pressure even up to 25-30 percent.

However, when applied topically, only 5 percent of the effective compounds reach its destination: thus many patients rely on other marijuana and medical cannabis products than CBD eye drops.

Many prefer to vape the CBD or use it as an edible oil to get the most benefit.

CBD Eye Drops Benefits

CBD oil has thought to have multiple benefits ranging from pain-relieving to decrease in anxiety and depression. So it is no wonder that CBD has also been used in CBD eye drops to help relieve pain and treat glaucoma by decreasing IOP.

CBD Eye Drops for Glaucoma

As of right now, there is no permanent cure for glaucoma. However, many studies have shown that cannabis compounds, THC and CBD, are a very effective way of treating glaucoma.

For instance, in open-angle glaucoma, which affects over 95 percent of the people with glaucoma, the intraocular pressure increases behind the eye and CBD can help relieve that pressure. Additionally, one of the first studies that were concluded regarding relieving glaucoma symptoms, specifically IOP, showed that CBD could reduce intraocular pressure by 25-30 percent.

However, the problem was that the benefits lasted only for a few hours so cannabis should be consumed multiple times a day to keep up with the IOP and pain relieving benefits.

After this, studies were done to understand how the topical application of CBD would work. The idea was that by applying CBD drops directly onto the eye, adverse reactions and side effects that resulted from the continuous use of CBD could be avoided.

However, because of the lipophilic profile of CBD eye drops, only 5 percent of the beneficial compounds got to its target.

CBD Eye Drops for Pain

The cornea of the eye has multiple sensory nerve endings and this makes it very sensitive to touch chemicals and temperatures. Any contact with the cornea results in an involuntary reflex that makes you blink

An injury to the cornea often comes with neuropathic pain and this is usually related to damaged nerve terminals and pain receptors. Scientists have been testing different options for managing neuropathic pain, and these include cannabinoid treatments.

Cannabinoids bind to cannabinoid receptors that are very localized in areas of skin and brain that are related to pain transmission. Endogenous cannabinoids activate the receptors which reduce inflammation.

Medical marijuana has always been proven to alleviate pain.

That is why many patients with severe illnesses, such as back pain, cancer, epilepsy, multiple sclerosis, post-traumatic stress disorder, Alzheimer’s disease and so on, choose to use medical marijuana and CBD products to treat their symptoms.

Cannabis oil has been used for the treatment of glaucoma as well – many choose to vape CBD or use it as edible oils to reduce IOP and relieve pain.

Where to Buy CBD Eye Drops

Doctors and researchers are still trying to figure out the best formula for CBD eye drops, considering it has been challenging to come up with a formula that allows CBD oil to be applied topically and still provide the most effective results.

You may find CBD eye drops online. However, before ordering them, you should check your local laws and consult your doctor.

Your doctor will be able to tell you if the formula used in the CBD eye drops is an effective one, and whether or not it interferes with the current medications you may have.

Proper Dosage and Use

The problem when using cannabis for treating glaucoma has been the fact that the benefits of smoking CBD only last a few hours. CBD eye drops were thought to provide a solution, as you would apply the CBD oil topically and directly onto the eye.

Studies have shown that using over 40-milligram doses may be harmful, so the dosage should be kept between 10 and 20 milligrams.

Are CBD Eye Drops Right for You?
