Can Cannabis Help With Glaucoma Treatment?

You might be a little worried when you see the word ‘cannabis’ in the title itself; don’t worry, we are not talking about marijuana here. Instead, THC is just one of the many compounds in marijuana plant. It offers mind altering effects, and binds itself to the cannabinoid receptors in the brain – which can be quite useful for medicinal effects.

What is Glaucoma?

It is a common eye disease that is encountered by 60 million people over the world. It is the leading cause of irreversible blindness and also leads to blindness if left untreated.

Types and Symptoms

Generally,there are two common types

  • Primary Open-Angle
  • Acute Angle-Closure

For Primary open-angle , there may not be visible symptoms. Generally the loss of peripheral vision occurs, but it may not be detected until the advanced stages. Symptoms generally associated with the Acute angle-closure glaucoma include:

  • Blurred or hazy vision
  • Appearance of halo around light
  • Eye pain, nausea and vomiting
  • Sudden loss of sight

THC and CBD Treatment

  • THC has been shown to decrease the pressure of the optic nerves giving comfort to the patient. The effects are noticeable after smoking marijuana and are temporary. Smoking THC also causes the symptoms to recede for a short time.
  • There are various scientific studies which prove the inhalation of marijuana smoke reduces intra-ocular pressure. Some of them are mentioned below.
  • A study in 1979 published in International Journal of Pharmacology and Biopharmacology revealed that smoking marijuana relieved the pressure in the eyes for about 3 to 4 hours.
  • The same results were noted in another article published in the Ophthalmology in 1980.
  • Cannabis oil has also been proved to be beneficial in reducing the eye pressure and giving the patients relief from symptoms. The effectiveness was noted in various studies including the one’s discussed below.
  • A research conducted in 1981 used THC in light mineral oil for administering directly to the eyes. The intra-ocular pressure was reduced in the participants for 8 to 12 hours. The same findings were also highlighted by an author of the research in another publication in 1982.
  • A 2000 research used a non-psychoactive derivative of CBD to topically treat rabbits. The results of reduced pressure lasted up to 6 hours after the application.
  • Both THC and CBD can give you relief, but they cannot treat it. Both can be used for temporary relief and along with normal treatment. THC is prescribed more often in advanced stages where it becomes more useful.

How can CBD Help?

  • Some studies have shown that CBD and THC act as antioxidants and neuroprotective agents which increase the survival of cells inside the eyes and retina.
  • It also helps to reduce retinal neuron death.
  • One study also shows that it may slow the process of loss of vision in the eyes.
  • It also helps in low-light vision which makes it great for the disease we are talking about.
  • It may also decrease the pain in the eyes. It can also help with inflammation. Cannabidiol is known to help by reducing the intensity of pain and are beneficial for patients.

Dosage

The recommended dosage is 20 mg to 40 mg. It is not advised to go above 40 mg as it can actually increase the intra-ocular pressure. It’s one of the most effective ways to deal with glaucoma today. Have you thought about trying it out yet?
