CBD for Dogs with Glaucoma

What is Glaucoma?

Glaucoma is a medical condition in which eye pressure gradually increases. The final result of this pressure increase is the loss of vision as the optic nerve is afflicted with time.

The increase in pressure inside the eye is usually a result of the accumulation of excess aqueous humour in the eye. The aqueous humour is a clear liquid which the eye creates as a natural form of protection from foreign objects like wind, and dust. The liquid also provides nourishment to eye tissues.

The common name for this pressure build-up is Intraocular Pressure or IOP.

Regularly, this Intraocular Pressure is between 10-20 mmHg with proper regulation but in a dog suffering from glaucoma, it can be anywhere from 30 – 50 mmHg.

Factors that may result in Intraocular Pressure increase

The factors that lead to glaucoma differ depending on the form of glaucoma. For Primary Glaucoma, the factors include:

  • Physiological traits
  • Physical traits

These traits are obtained through the genetics of the dog.

The factors responsible for secondary glaucoma include:

  • Inflammation
  • Advanced cataracts
  • Chronic retinal detachment
  • Tumors
  • Eye cancer
  • Infections

Are certain breeds more likely to have Glaucoma?


The following are dog breeds which are more likely to have glaucoma as a result of their genetics:

  • Alaskan Malamutes
  • Dalmatians
  • Chow Chows
  • Siberian Huskies
  • Poodles
  • Cocker Spaniels
  • Chihuahuas
  • Samoyeds
  • Jack Russell Terriers
  • Basset Hounds
  • Beagles
  • Great Danes

In addition to the breed, dogs around the age of 3-7 years and above have a high chance of developing this condition.

How is Glaucoma Treated?

Early diagnosis is necessary for the effective treatment of Glaucoma. This is to ensure that the treatment occurs before extensive damage to the eye.

If there is too much delay before treatment, the eye may physically stretch which results in permanent loss of vision.

Glaucoma currently has no cure but there are certain control measures. These include:

  • Minimizing aqueous humour production
  • Reducing pain
  • Excess fluid drainage

An important reminder is that any dog that has experienced glaucoma in one eye has a high chance of having glaucoma in the other.

Can CBD Help Dogs With Glaucoma?

Cannabidiol, or CBD, is a molecule which is present in hemp plants and cannabis as well as Simply Pets CBD Dog Treats.

There have been various studies on the positive effect of cannabis in the treatment of glaucoma. In 1971, there was a publication of a study which stated that cannabis ingestion can lead to about 30% reduction in the intraocular pressure of glaucoma patients. There are other studies which prove the positive effect of CBD and THC against glaucoma.

Administering CBD Supplements

The best way to administer CBD supplements as a treatment for symptoms of glaucoma in dogs is either as a treat or CBD oil.

The absorption of CBD oil is much faster which means the dog will experience rapid relief from the symptoms. The administration of this oil is usually under the tongue.

Using treats offers a much slower relief. This is because digestion is necessary for it to take effect. Regardless, using treats is much easier.

If the condition of the dog is severe, you may need to combine the use of CBD oil and treats.
