Understanding Glaucoma

Glaucoma is a disease caused by damage to the eye’s optic nerve. This usually happens when there is a build-up of fluid which then causes an unusual amount of pressure inside the eye, resulting in vision loss.

How The Eye Works

Before learning how glaucoma can affect dogs, it’s important to have a general understanding of how the eye works. Vision is determined not only by the eyes but also by nerves, and of course, the brain. This is the case in both people and animals.

When we look at something or someone, light enters our eyes through the cornea. This light is then passed through to the retina, a sensitive layer at the back of the eye. These light rays then travel through tons of nerves, pass on to the optic nerve, and then travel all the way to the brain. The brain then creates a picture, allowing us to see what’s right in front of us.

For this process to work correctly, the eye needs to continue its production of a fluid known as aqueous humor. This watery fluid nourishes the front of the eye to protect it from the environment. When functioning correctly, the fluid automatically drains from the eye. If aqueous humor doesn’t function correctly, the results can be damaging.

The unnecessary build-up creates a pressure known as Intraocular Pressure (IOP). In a normal eye producing aqueous humor correctly and then draining it too, pressure should measure between 10 and 20 mmHg (mmHg is a standard way of measuring pressure). With the correct amount of pressure, eyes keep their shape and remain strong.

If the pressure is too high, there can be significant damage to the eye, which may eventually cause vision loss. Commonly this damage affects the optic nerve, which is a vital ingredient in healthy vision. Such damage results in a condition known as glaucoma.

Types of Glaucoma in Dogs

Primary Glaucoma

In dogs with glaucoma, the pressure inside the eye can reach as much as 30 or 50 mmHg. This increase in pressure is known as chronic ocular hypertension. Primary glaucoma is the most common form of glaucoma in dogs and is generally a result of an inherited abnormality. This abnormality leads to a build-up of liquid, as the eye is unable to drain the aqueous humor correctly.

Secondary Glaucoma

Secondary glaucoma is a heightened condition of primary glaucoma. According to American Kennel Club, this happens when another eye infection is present, leading to secondary eye infections.

Some of these eye infections may include:

  • Tumors
  • Infections
  • Advanced eye cataracts
  • Eye cancer
  • Inflammation
  • Chronic retinal detachment
  • Blood clots
  • Eye lens-iris edge attachment
  • Prominence or redness of blood vessels in the white part of the eye

What are the Symptoms of Glaucoma?

Usually, the first sign of canine glaucoma is a pain in or around the eye. Dogs often avoid contact with their eye when in pain, whereas humans may rub the area. Sometimes, dogs may push their head against hard objects to try and relieve the pain. The downside is that it can be difficult to identify because your dog may only show subtle signs, which can be quite easy to miss.

Other early signs of glaucoma include:

  • Eye spasms
  • Loss of appetite
  • Behavioral changes
  • Cloudy eye
  • Enlargement of the eyes
  • Eye redness
  • Pupil dilation
  • Unresponsiveness of the pupil
  • Vision loss

However, if left untreated and there’s prolonged eye pressure, dogs affected with this condition can develop severe symptoms such as:

  • Eye lens displacement
  • Enlarged eyeballs
  • Tear in the corneal membrane
  • Aggressive behaviors
  • Deterioration of affected eye
  • Pain

Many pet owners are unaware that they can ask their vet to check their pets’ intraocular pressure. This is one of the best ways to get an early diagnosis or even prevent glaucoma altogether. It’s even more important to keep a check on your pets’ intraocular pressure if they’ve had any of the symptoms mentioned above. This means they are more likely to develop glaucoma.

Which dog breeds are more susceptible to Glaucoma?

Sadly, it is known that certain breeds of dog are much more likely to develop glaucoma than others. So far, across the world, over 40 dog breeds have been affected by the condition and most have been inherited.

Breeds known to be prone to glaucoma include:

  • Akitas
  • Shih Tzus
  • Shar Peis
  • Poodles
  • Beagles
  • Jack Russell Terriers
  • Siberian Huskies
  • Dalmatians
  • Bullmastiffs
  • Great Danes
  • Schnauzers
  • Basset Hounds

It’s most likely that dogs will develop glaucoma between ages 3 and 7, however, it can begin at any time in their life. Typically, it doesn’t manifest before age 2 but is still possible.

Treating Glaucoma in Dogs

In cases of glaucoma, fast diagnosis and treatment are of the utmost importance. The longer the condition goes unnoticed, the more likelihood there is for long-lasting damage to the eye. Leaving the condition to manifest for too long can even result in the eye physically stretching. In cases like this, it’s bound that dogs have already reached complete and permanent blindness.

Early diagnosis is key in vets being able to slow down the onset of glaucoma. They can do this through both surgical and medical treatments.

Sadly, the difficulty with glaucoma is that it is incurable. Furthermore, the harsh realization is that almost half of all dogs diagnosed will become blind in the affected eye in less than 1 year. As a result of there being no cure, there are usually 3 focal points when it comes to treatment:

  • Pain management
  • Aqueous humor production management
  • Aqueous humor drainage management

Once diagnosed, vets often focus their initial attention on reducing intraocular pressure as speedily as they can. They normally do so by issuing specialist eye medicine. Sometimes, vets decide it’s best to immediately start draining the excess fluid from the eye. This is then followed by cyclocryotherapy, a process used to destroy the ciliary body which produces the fluid.

By doing this treatment and getting started on the right medication, nerve damage will likely be delayed, and eye health will be prolonged. It’s even possible for this treatment to have such a positive impact that it drastically reduces glaucoma’s effects and can even stop it in its tracks. Unfortunately, this scenario is very rare.

More often than not, affected dogs will lose their eye altogether. Sometimes, their eye will be replaced with a prosthetic one, or the gap may be closed. Even though losing an eye can hinder a dog’s abilities, they are often capable of living a happy and fulfilling life. They’ve often already adapted to their reducing vision since developing glaucoma and so can continue life successfully after complete removal.

It’s important to note that once glaucoma has developed in one eye, it is likely to start in the other eye in the future. Therefore, regular health checks up are key. It is strongly advised to keep a check on your dog’s intraocular pressure.

Early Research on Using CBD for Dogs With Glaucoma

Hopefully, now you have a good understanding of how glaucoma can affect dogs. Next, let’s talk about the role of CBD in its treatment. It’s likely that you’ve already heard a lot about CBD as it’s a much-talked-about subject as an alternative treatment. CBD (cannabidiol) is a molecule of the Cannabis plant. It is used for a wide variety of different conditions and illnesses.

Research into the use of CBD specifically for glaucoma goes as far back as the 1970s. This early research identified that Cannabis could lower intraocular pressure in people suffering from glaucoma. One of the earliest studies from 1971 identified that consuming Cannabis could decrease this pressure by 30%.

Since then, further studies have shown that cannabinoids like THC and CBD can help protect certain eye cells from glaucoma. Another study published in 1998 showed that Cannabis can reduce intraocular pressure in over 60% of glaucoma patients. Despite all this research, many ophthalmologists do not prescribe Cannabis as a treatment for glaucoma.

If you’re wondering why sadly, the effects of Cannabis on intraocular pressure are short-lived. Also, as glaucoma patients must keep their IOP in check 24/7, Cannabis would be needed every few hours, which certainly isn’t advised if using Cannabis contains psychoactive THC.

The most common reason doctors are hesitant in prescribing Cannabis as a treatment for glaucoma is its potential negative health factors. Smoking cannabis can actually increase IOP, as well as cause several other health risks.

The good news is that many studies suggest that CBD, CBN (cannabinol), and CBG (cannabigerol) can offer great help in reducing IOP in animals. It’d be no surprise if a certain question has popped into your head when reading this:

Is this article suggesting I allow my pet to get high?

You’ll be pleased to know that the answer is, absolutely not!

CBD does come from the Cannabis plant; however, it does not have the same “high” effects as smoking marijuana. The reason marijuana is used as a recreational drug is due to its high content of THC. THC is the psychoactive ingredient found in cannabis.

THC does offer its own benefits; but, high quantities of the chemical can be very detrimental to health. Most supplements available for pets contain little to no THC. Meaning it will not get them high but will have the desired effect of helping to reduce intraocular pressure.

How does CBD help in alleviating symptoms of glaucoma?

The 1984 Experimental Eye Research study shows that CBD pet supplements can reduce intraocular pressure in many animals, including rats. This research also found that the more CBD took, the greater the results. This suggests that offering appropriate dosages can have long-term benefits for dogs with glaucoma.

Many pet supplements containing cannabis are produced with hemp extract, which contains all the goodness of CBD, CBN, and CBG. This is a beneficial way of adding appropriate forms of cannabis to your dog’s diet as it provides a mix of chemicals rather than just one.

How do I incorporate CBD supplements into my dog’s diet?

It is known that cannabis supplements can help improve a range of conditions in dogs, including cancer, chronic pain, anxiety, epilepsy, and of course, glaucoma. There are several ways CBD can be incorporated into any dog’s diet, one of which is by administering CBD oil straight into their mouth.

Many CBD oil products come with a dropper allowing you to easily dispense the correct dosage into their mouth. Issuing CBD in oil form is one of the most effective methods as the oil is absorbed faster, meaning the benefits are seen quicker too.

Alternatively, you can either buy ready-dosed dog treats or drop the oil onto your dog’s favorite treat yourself. By doing so, your dog may be happier to take the CBD, but the effects may take a while longer.

It can be useful for dogs with more complex illnesses to offer a mixture of oil and treats to keep their dosages at the right level. Check out this page for more information on issuing CBD.

Are Other Dogs Using CBD for Glaucoma?

We now know a growing interest in CBD pet supplements, but you may be particularly impressed to hear that the CBD pet market doubled in sales between 2008 and 2014. It’s no wonder the market is growing, considering that CBD can be used to treat a range of pet conditions.

Here are some real examples of pet owners that have turned to CBD to help treat glaucoma and have seen success in doing so.

This is Odie, a 13-year old Beagle mix from Campbell Hall, New York. During a crucial time of his life, he was diagnosed with glaucoma and has been suffering immensely. His veterinary ophthalmologist prescribed Odie two different eye drops, which need to be administered continuously 8 times a day.

However, this is only a short-term solution, and unless he gets surgery, Odie would have to be put down. At the time, Odie had an increased intraocular pressure of 35 and 30, which is really high. With Odie’s life on the line, his owner started looking for an alternative treatment.

That’s when his owner found out about Canna-Pet and decided to give it a try. His owner administered Odie with Canna-Pet’s Advanced CBD twice a day. After the continuous use of CBD, Odie’s eye pressure was back to normal, 8 and 6. The amazing thing about it is that he maintained that normal eye pressure even after 10 months. Now his eye and overall health are better than ever, thanks to Canna-Pet.

Here we have Zeus, an adorable Chow Chow who used to suffer from glaucoma. that’s right, ‘used to.’ Before taking Canna-Pet CBD Liquid, Zeus’ eye pressure was 31 and 50. As we know, the normal eye pressure is 20 and below, and anything above 20 is considered high.

After a few months of consistently taking Canna-Pet’s CBD Liquid, Zeus’s eye pressure has improved to 18 and 20. Needless to say, his owner and, of course, Zeus himself are very happy with these results.

Conclusion

Hopefully, this article has given you a good understanding of glaucoma and how CBD can aid pets suffering from this condition. There are various testimonials you can read about the effectiveness of CBD to treat glaucoma. The best way to learn about a product is by doing in-depth research. As you’ve reached the end of this article, I hope you found your answer to some of your questions. Fingers crossed, you are now on a journey to improving your dog’s condition and can provide some much-needed comfort. We’re sure you’ll see some great results if you follow the advice provided in this article and wish you the very best!

Expert Tip

In some states, veterinarians are not allowed to directly prescribe or recommend CBD supplements to their dog owners. However, this doesn’t include pet owners asking if they can use CBD on their dogs. So if you’re curious about using CBD as a treatment, you still may ask your vet about it and see if your dog will benefit from the healing effects of CBD.

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.
  • Shaking.
  • 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.

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.

Final Thoughts

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.
