Dog Glaucoma Treatment, Can CBD Oil Help?
Dogs, just like people, can develop glaucoma. Although severe eye diseases like glaucoma may seem like a simple eye problem, these are actually emergency eye problems that may progress and become worse in a short period of time. Approximately 40% of dogs will lose their vision due to glaucoma.
If your dog’s eyes are red, misty, itchy or extremely weepy, it’s best to consult with your veterinarian immediately. With the high frequency of predisposed glaucoma occurring in purebred dogs, it’s important to know what to look out for so that you don’t miss the early signs. Mixed dog breeds are also susceptible to glaucoma.
Pain associated with glaucoma often shows up as behavioral changes in dogs. That said, you’re going to need to know how CBD oil can help dogs with glaucoma.
What is Glaucoma in Dogs?
Glaucoma takes place when there is an imbalance in the production and drainage of eye fluid. (aqueous humor) This then results in a buildup of fluid in the eye that increases eye pressure to very high levels, and causes a lot of pain. It is important to note that increased eye pressure in dogs should be taken seriously, since it may result in the destruction of the retina and optic disk.
There are Two Types of Glaucoma: Primary and Secondary
Primary entails the eye’s inability to drain through the filtration angles of the eye.
Open-Angle Glaucoma (Primary)
This is painless with a gradual development of blind spots or loss of vision over a long period of time. Primary open angle glaucoma is the most common type of glaucoma in dogs. Your veterinarian will need to use a tonometer to measure eye pressure in your dog.
The Dog Breeds Most Commonly Affected by Primary Open-Angle Glaucoma are Shiba-Inus, Beagles, and Shih- Tzu’s.
Close-angle glaucoma (Secondary)
This occurs due to a sudden increase in eye pressure, and is accompanied by severe pain, eye redness, and may cause a loss of vision. With glaucoma affecting approximately 1.7% of all dogs in the US, it’s necessary to visit your veterinarian immediately if you suspect that your dog is suffering from any eye problems.
Glaucoma will usually benefit from long-term treatment. Although early signs of glaucoma are hard to distinguish, your veterinarian will use the following methods to diagnose and treat glaucoma in your pooch.
-Tonometer to measure eye pressure
-Medical or surgical treatment or a combination of both to decrease eye pressure
-Medication that will draw out eye fluid or decrease the production of eye fluid
Symptoms of Early Glaucoma May Include the Following:
- Mild congestion of the conjunctiva veins
- Early eye enlargement
- Slight dilation of the pupil (not responding to light)
- Behavioral changes
- Spasmodic winking
- Blood vessels are red
- Cloudy front part of the eye
- Vision loss
If your dog is not treated immediately for glaucoma and has a prolonged eye pressure within the eye, symptoms may result in the following:
- Displacement of the eye lens
- Enlargement of the eyeball
- Breaks in the corneal membrane
- Behavioral changes
- Progression of the advancement of degeneration within the eye
Symptoms of Secondary Glaucoma or Glaucoma Resulting from Secondary Eye Infections May Include the Following:
- Redness of blood vessels in eye whites
- The front part of the eye may be cloudy in appearance
- High eye pressure
- Pupil constriction may occur
- Iris may attach to the cornea or eye lens
- Iris edge may attach in a circular motion to the eye lens
- Debris that is inflammatory may be visible in the front part of the eye.
- Lack of appetite
- Lethargy accompanied by a headache from eye pressure
New 2018 Study adds That CBD Mixed With THC May Worsen Glaucoma, Raise Eye Pressure
A new 2018 study from Indiana University found that “ Tetrahydrocannabinol, or THC, the primary psychoactive ingredient of marijuana, was found to effectively lower pressure in the eye, as has been previously reported. But the study found that the use of CBD in combination with THC blocked this effect.”
The study also states that “the chemical that causes this rise in pressure is cannabidiol, or CBD, a non-psychoactive ingredient in cannabis that is increasingly marketed to consumers in products such as oil, gummies, creams, and health food. It is also approved in many states as a treatment for conditions such as pediatric epilepsy,” via Science Daily
The study concludes with the following “ There were studies over 45 years ago that found evidence that THC lowers pressure inside the eye, but no one’s ever identified the specific neuroreceptors involved in the process until this study. These results could have important implications for future research on the use of cannabis as a therapy for intraocular pressure.”
What is CBD Oil?
Hemp refers to the cannabis varieties that are grown as an agricultural crop, and also contain low amounts of THC(tetrahydrocannabinol). THC is federally illegal in the US if it contains a higher amount than the O.3% allowed for use, though it’s been approved for both recreational and medical use in Canada, and numerous US states.
For all CBD pet products to be legal, they need to have less than 0.3% THC. CBD is natural, safe, and is derived from hemp and cannabis. Most CBD dog products will use CBD from hemp. That said, there is no “high” and dogs will not consume THC or tetrahydrocannabinol, resulting in psychoactive effects with your dog getting “high”.
CBD is a non-psychotropic phytocannabinoid and yields therapeutic and medicinal purposes for dogs. To help you understand more about the benefits of CBD oil for dogs dealing with glaucoma, let’s look at some research.
CBD Oil for Dogs with Glaucoma Pain
The potency of CBD oils both in capsule form, and those in bottles with droppers are much more potent and are sometimes more difficult to administer to difficult dogs that don’t take meds via droppers.
A few product lines contain phytocannabinoids, terpenes and fatty acids which support a huge range of ailments like phobias, joint pain, inflammation, digestive issues, mobility, seizures, and anxiety.
CBD Possible Side Effects in Dogs
What to Look for in CBD Oil Products for Dogs with Glaucoma?
- Hemp CBD should be 100% food grade
- Should be made using CO2 extraction
- No solvents like butane
- Full-spectrum lab testing by a third party for purity and potency
- Lab certificates need to be available for all pet parents
- Pesticide and herbicide free
- Made with non-GMO hemp
- Grain-free functional chews if purchasing CBD DOG TREATS
- Numerous additives in treats like pumpkin, coconut, turkey, sweet potato, blueberry with antioxidant properties.
Tips on CBD Oil for Dogs with Glaucoma
When it comes to dogs suffering from glaucoma, or chronic ocular hypertension, we need to be aware that eye pressure can reach 45-65 mmHg, making this an incredibly painful condition for dogs. Consulting with your veterinarian for immediate diagnosis and treatment whether medical or surgical is step one.
Your veterinarian will most likely recommend long-term treatment and drugs that will draw out the fluid from the eye, as well as other drugs that will decrease the production of fluids. It is important to keep in mind that although eye pressure is lowered initially, it will need to be stabilized throughout your dog’s lifetime to prevent further eye problems.
CBD Oil and Keeping Your Dogs Safe
- Ask for proper and accurate labeling and dosage instructions.
- Look at each CBD product and research what each CBD product does and does not contain.
- Find out where and how it was manufactured.
- Look at the research and find out more about the potential therapeutic effects
- Find out more about the risks with the specific CBD product by understanding the exact composition. Just because others are purchasing it, does not mean it’s right for your dog. Consult with your vet first!
- Look for misleading labels.
- Look out for harmful contaminants that may be potentially deadly. (Know what to look for)
- Research the 3 rd party labs associated with your CBD product.
- Make sure that CBD dog products are used responsibly
With all CBD dog products including edibles, the dosage will vary according to the brand you choose. Dogs will need different dosages, so it’s important to discuss with your vet first prior to using any CBD dog product. Consult with your veterinarian for safe and accurate dosage instructions.
Finding out whether the CBD oil you purchase is safe for your furry best friend should be easy!
Today with the unsanctioned medical use of CBD- based products containing a variety of oils, supplements, gums, and some with a very high concentration of extracts, we should all become familiar with what the safety norms are, and what to look out for when purchasing a safe, high-quality CBD oil free of contaminants that may be dangerous to your dog’s health. That said, always consult with your veterinarian prior to purchasing any CBD product for your pooch!
CBD Oil and Glaucoma
CBD breaks down peroxynitrite on contact. Because it’s an antioxidant, it prevents the formation of peroxynitrite inside the cell. CBD may prevent blindness by preventing apoptosis of neurons. That said, CBD with CBN, and CBG may help with glaucoma in dogs.
A 2003 study demonstrated that “in glaucoma, the increased release of glutamate is the major cause of retinal ganglion cell death. Cannabinoids have been demonstrated to protect neuron cultures from glutamate-induced death, “via PubMed. This study concluded that “The effect of THC was in part mediated by the cannabinoid receptor CB1. These results suggest the potential use of CBD as a novel topical therapy for the treatment of glaucoma.”
A 2006 pilot study wanting to assess the effect on intraocular pressure (IOP) and the safety and tolerability of oromucosal administration of a low dose of delta-9-tetrahydrocannabinol (Delta-9-THC) and cannabidiol (CBD) on people stated the following, “A single 5 mg sublingual dose of Delta-9-THC reduced the IOP temporarily and was well tolerated by most patients. Sublingual administration of 20 mg CBD did not reduce IOP, whereas 40 mg CBD produced a transient increase IOP rise,” via PubMed.
That said the use of CBD oil for glaucoma has been backed up by several studies. In a 1984 study, “i ntraocular pressure, ocular toxicity, and neurotoxicity after administration of cannabinol or cannabigerol lowers ocular tension considerably. While cannabinol had a modest effect on intraocular pressure after a single dose, it caused a more significant reduction in ocular tension during chronic administration. Cannabigerol had similar effects, but the magnitude of response to its chronic administration was greater,” via PubMed.
This study suggests that the use of hemp-based products and cannabis supplements, when administered in the right dosage, proved effective in treating glaucoma in dogs. As usual, consult with your veterinarian for the best CBD oil products for dogs with glaucoma is recommended. That said, hemp-based CBD pet products offer all the chemicals from the hemp plant which includes CBD, CBN, and CBG, as well as numerous other compounds like terpenes and cannabinoids.
The Importance of Opting for a High-quality, Full-Spectrum CBD Vet Approved Product
When looking at all the CBD pet products, the most important consideration is if a CBD product uses an isolate or a full-spectrum oil. A full spectrum oil is the most potent and is derived from the entire plant.
The extraction of the oil takes place via a carbon dioxide process called CO2 extraction which entails using pressurized carbon dioxide to extract the CBD from the entire plant. CO2 functions as a solvent when reaching extreme temperatures, yet because it is under the boiling point, it’s cold. It is processed to create oil from the plant. It is also a clean and environmentally friendly process.
CBD Dog Treats
CBD edibles or dog treats make dosing easier for fussy dogs. Opt for natural, vegan,non-GMO, and US sourced and manufactured. CBD dog treats and edibles that are not organic or natural may contain pesticides, solvents or fungicides.
When choosing a CBD oil or dog treats for dogs with glaucoma , it will be necessary to do the following:
- Consult with your veterinarian
- Opt for a high-quality CBD oil or CBD dog treats. Read the dosage carefully.
- Explore the CBD company vigorously, and check if the product is veterinarian approved.
- Triple check dosing for glaucoma purposes and pain with a CBD savvy veterinarian.
- Read product reviews and comments.
- Read through research papers news articles, and check for recalls
- Don’t think that because the product is out there that it’s 100% safe to use. Research sourcing and manufacturing practices.
Nowadays, thanks to the internet, pet parents can do a lot of research. Your dog’s good health depends on you. Not only is it safe and non-toxic, but CBD oil can also give you peace of mind in that apart from helping dogs with glaucoma, it can also ease your dog’s pain as well.
With all the positive effects of CBD oil for dogs that may help treat anxiety, pain, cancer, seizures, joint pain, tumors, and glaucoma, full-spectrum hemp CBD products may be a good choice. As usual, consult with your veterinarian first.
An Honest Look at CBD Oil for Dogs With Glaucoma
Having to witness your loyal and loving furry companion in a state of pain is, without a doubt, the greatest distress any pet owner can imagine. We all strive to invest in our dog’s health from the moment we first hold them, but an illness can creep up silently. Before we fully have a chance to realize what is going on, the condition has heavily progressed and we’re faced with incredibly difficult decisions.
Glaucoma is one of such conditions. It has an immense fast speed of progression: 40% of dogs affected by glaucoma will become blind within months, many will have the eye removed. As many owners struggle to cope with managing this condition in their dogs and weigh their options of treatment and medication, alternative and holistic veterinary medicine advocates for CBD oil as a possible option in managing (even alleviating) the symptoms of this sensitive condition.
Before trying something new for their dog’s health, most people wish to do their own research first – google the topic and read up on the information. But here is where it gets tricky. When you search the web for information on how CBD affects glaucoma, you emerge from the search more confused than you initially went into it.
Many sources claim that CBD is absolutely the way to go, but just as many say it can make the condition worse. In this article, we’ll be looking at the details of how exactly CBD affects glaucoma, what the research says, and the truth you have to know before taking this leap of faith.
What is glaucoma and how does it affect dogs?
Glaucoma is a condition where the pressure in the eye gets very high, causing the dog a lot of pain, enlarging the eye, impairing the vision, and eventually leading to full blindness. In some cases, the affected eye has to be removed because of the severe pain it’s causing the dog. If glaucoma is identified in one of the eyes, there is a very high chance that the other eye will get affected as well, in a matter of mere months.
What causes dog glaucoma?
Glaucoma is caused by a blockage in the draining of the eye fluid called the aqueous humor. The amount and balance of this fluid are directly connected to intraocular pressure, also referred to as IOP. When there is a blockage, and the eye fluid cannot drain out while the cells continue producing it, the pressure in the eye increases.
There are two main reasons for this blockage. The first is genetics. For some dogs, glaucoma is an inherited condition connected to their breed. This is known as primary glaucoma. Some of the most affected breeds are found among the Spitz breeds (such as Siberian Husky, Elkhound, Samoyed, Chow Chow). Other breeds predisposed for glaucoma are Cocker Spaniel, Poodle, Shih Tzu, Basset Hound, and Jack Russel Terrier.
The second reason for the blockage can be a previously undiagnosed eye disease that affects the balance of the eye fluid and so increasing the IOP. This is known as secondary glaucoma.
What are the main symptoms?
It’s very important to be aware of the fact that, in most cases, by the time the owner notices any symptoms on the dog’s eyes, glaucoma will have progressed to the point where vision is already impaired, often beyond repair. Early detection of glaucoma is rare because the first (and most important) symptom is pain. Increased IOP causes the dog a lot of pain.
Unfortunately, dogs can’t tell us with words when they are hurting. In fact, they cope with the pain in a way that is opposite to ours. For example, when humans are experiencing pain, we rub and hold the area that hurts us. In contrast, dogs avoid touching the painful area altogether. The pain that is a result of a high IOP feels like a constant headache and dogs have a hard time communicating that. This is why pain is so hard to recognize in dogs – it’s far from obvious.
These are some subtle signs of head and eye pain:
- Refusing to be touched, especially on the head and around the eyes.
- Sudden changes in mood and behavior, such as irritability and snapping.
- Decreased energy and apathy, for example, refusing to go on a walk or not wanting to play.
- Decreased appetite.
- Increased panting, even without any exercise.
- Changes in sleep patterns, such as not sleeping (pacing around) or sleeping too much.
The second symptom is vision impairment and blindness, but just like with pain, it’s hard to detect. Dogs are very adjustable – if they lose vision in one eye, they will adapt to the change quickly, making it near impossible for their owner to notice. They will function very well with their remaining eye, though you may notice they are not observing things in their peripheral vision.
Other symptoms of glaucoma are related to the physical changes in the dog’s eye. For example, you may notice that your dog’s eyes look bloodshot, or the cornea (the transparent part of the eye) appears cloudy. The pupil may appear dilated and unresponsive. Because of the high IOP, the eye eventually enlarges, which is the most obvious and visible sign. Unfortunately, by the time this happens, the eye is already blind.
How is canine glaucoma diagnosed?
Reading through the symptoms mentioned above, you may be wondering how can one possibly know if their dog has glaucoma, considering the symptoms are so hard to spot. If you keep a close eye on your dog, as most owners do, you’ll be able to notice at least one of the mentioned symptoms. The signs of head pain are usually the first ones, so pay extra attention to those. If you notice any of the symptoms, book an appointment with your holistic veterinarian as soon as possible.
The only way to properly diagnose dog glaucoma is by measuring the intraocular pressure with a tonometer. Once diagnosed, the focus is on saving the dog’s vision, if at all possible. Since glaucoma is often the result of a pre-existing, undiagnosed eye condition, the priority is also to diagnose that condition and treat it. If the eye is already damaged beyond repair, the next step is managing the dog’s pain and preventing glaucoma from affecting the other eye as well. Some dogs have to have their affected eye surgically removed as a result.
A Closer Look at CBD Oil and Dog Glaucoma
Since there is no clear path to take with dog glaucoma, no magic wand that would work each time and reverse the condition, many owners are stuck pondering which treatment, therapy, or medication would work best for their dog’s illness. As CBD oil products are on the rise, the big question remains: can CBD be helpful for dog glaucoma? Let’s take a look at what the science says and what your options are!
What are the benefits of using CBD oil for dog glaucoma?
The first major benefit is that studies have proven CBD’s ability to help with pain management. Seeing as pain is one of the main symptoms of glaucoma and one that is otherwise not easily managed without putting your dog on strong medication, CBD can be a very welcome and helpful supplement, giving your dog a chance at regular life while the other aspects of his glaucoma are being managed. This leads to the second aspect of using CBD for canine glaucoma – it has been proven to have an anti-inflammatory effect.
CBD can reduce the inflammation in the body, which can work wonders for the eye inflammation that is causing your dog pain, and ultimately the loss of vision. The classic management of this condition almost always involves anti-inflammatory medication. The introduction of CBD into the healing process can be a helpful, natural addition, with fewer side effects than regular pain medication.
For one, CBD does not have a psychoactive effect, so your dog will not get high from it. Classic pain and anti-inflammatory medications have been known to have strong side effects, including (but not limited to) vomiting, decreased appetite, severe stomach issues, kidney and liver failure. In comparison, studies have shown that side effects of CBD include (but are not limited to) tiredness, changes in appetite, and diarrhea.
One study revealed that CBD has the potential to be considered as, and further developed into, a treatment for glaucoma. It was discovered that CBD has neuroprotective effects, which is crucial in glaucoma treatment. Something that plays a big role in glaucoma is a neurotransmitter called glutamate. An increased production of glutamate, also known as glutamate-induced neurotoxicity, causes the death of crucial eye cells, leading to vision loss and blindness. Experiments have shown that CBD is a powerful protector against glutamate-induced cell death. As such, it has the potential to prevent glaucoma from progressing at a rapid speed.
Are there any downsides to using CBD oil for dog glaucoma?
Yes, there can be. Despite the promising research noted above, other research has shown that CBD does not lower the intraocular pressure. Mostly, CBD does not seem to have any effect on IOP, but a surprising study has shown there are cases where it may elevate it. This is an obvious cause for concern since it’s the high IOP in glaucoma that causes strong pain.
Another important thing to note here is that many people seem to reference and rely on countless studies that have shown THC lowers the IOP. Here is why this is problematic: first, THC is toxic to dogs, illegal in most countries, and not considered a safe long-term treatment. It only lowers the IOP for a very short time (a few hours) and seems to depend on sex – the male mice in the study had better results than the female.
Furthermore, managing the IOP needs to be done consistently, which means large amounts of THC would have to be taken daily to keep the intraocular pressure low. As mentioned, THC is not an appropriate treatment for dogs. The reason why this has to be emphasized is that the THC studies get referenced in countless blog posts, but they don’t apply to the non-psychoactive CBD. In fact, the study that discovered CBD can elevate the IOP also found out that CBD can interfere with THC’s ability to lower the IOP short-term if the two are taken together.
Now what? To use or not to use CBD for dog glaucoma?
Reading through this seemingly opposing research can not only be confusing but also stressful if your dog is suffering from glaucoma and you came here to get some answers. It’s important to understand the context of each research and what this means for the future of CBD in glaucoma treatment.
First, the intraocular pressure and glutamate-induced neurotoxicity are two different things. Most of the initial glaucoma treatments were solely focused on lowering the IOP until research showed that vision loss still happens even with the lower pressure; the eye cells are still dying. This is how the role of glutamate became recognized as an important factor in understanding and treating glaucoma. If you are now wondering which of the mentioned research is correct and should be trusted, the answer is both!
CBD can protect the cells in the eyes from neurotoxicity, it’s a powerful antioxidant that can stop the rapid cell death. It can also help with pain management and inflammation, especially one that could be connected to a pre-existing eye condition. But it may increase the IOP. This is why the right CBD dosage is the crucial thing.
The correct dose of CBD oil will determine your dog’s response to the treatment and to what degree he can be helped. When you begin supplementing with CBD in the case of glaucoma, make sure you have regular check-ups with your holistic veterinarian, to regularly measure your dog’s IOP – especially if you find that CBD is helping with your dog’s other symptoms and wish to continue with the supplement long-term. You may not find the perfect dosage on the very first try, so watch your dog closely and monitor the changes in his symptoms and behavior, then adjust the dosage (after consulting with your holistic vet) as needed.
How to find the right CBD oil dosage?
Dr. Robert J. Silver, who has over a decade of experience in researching how cannabis affects animals, suggests starting with the lowest possible dose twice a day and observing your dog as you go along. For some dogs, a low dose will be enough, while other dogs will need a higher one. The dose largely depends on the dog’s weight. Dogs who weigh more will likely need a higher dose of CBD than dogs who weigh less. Based on several studies and anecdotal evidence, dr. Silver lists the lowest dose as 0,05mg per pound (1 pound = 0.45kg), the medium dose as 0.10mg per pound and the highest as 0.25mg per pound.
The right dose also highly depends on the type of CBD product you purchase for your dog. Make sure you read the manufacturer’s instructions or contact them directly if you are not sure how the recommended dosage applies to their product.
CBD Oil for Dog Glaucoma Success Stories
In light of all this research and information, there is no greater comfort and inspiration than another dog owner’s honest story of success. Those are the stories that truly have the power to influence somebody to take a chance on CBD oil and give it a try with their own dog, especially when dealing with such a rapidly progressing condition as glaucoma. Here are two success stories that may give you the necessary glimmer of hope!
A 13-year-old Beagle named Odie was diagnosed with glaucoma and, as it is in most cases, by the time his owner realized the condition was present it has already progressed to a severe point. They were told that if Odie’s eyes aren’t removed within a month, he’ll have to be put down. Odie’s owner decided to try CBD and his high IOP dropped dramatically. Ten months later, his eye pressure was still normal; no eye surgery required.
There is also the case of Lola, an elderly English Bulldog, with glaucoma that was already visible on her eyes. She had many other health issues as well and was given pain and anti-inflammatory medication, without success. But after she was put on CBD, her eyes cleared up within two months, and her other conditions improved as well.
For more success stories, you can reach out to your holistic vet and ask them about specific cases that were successful. You can also check online reviews of CBD oil pet products or find testimonials in a few pet CBD Facebook groups.
While the initial stream of information on CBD oil and dog glaucoma may seem overwhelming, the silver lining of it all remains that there is hope for dogs who are suffering from this condition. CBD has big potential to be a helpful part of the treatment, on many different levels. It can manage the pain, reduce inflammation, and even protect the eye cells from damage.
Since glaucoma is a very serious condition that has to be managed constantly, you’ll want to be in touch with your holistic vet and keep an eye on your dog’s IOP, to make sure it’s not rising. As always, monitoring the dog’s symptoms and progress is a crucial part of the process.
Finding the right dose of CBD seems to be the key to managing this condition. Taking a chance on a natural approach that you haven’t tried before may seem scary at the beginning, but in light of all the positive information surrounding CBD oil and dog glaucoma, perhaps this is the puzzle piece you have been searching for.

My dog is a 16yr old poodle with arthritis, loosing his eyesight, and forgetting where he is at. I started him with CBD oil 50 Broad Spectrum (4months), 1 drop on a single piece of bread 2xs a day..I noticed he was confused , I changed the CBD oil to a 25 broad spectrum, once at night only. Seems to be helping for sleep and pain. His Alzheimers is sad but we help him around the house and yard cause he gets lost not being able to see well. If you get CBD oil and it reads Broad Specrum, that has no TLC and is the best for dogs.
