iCAN Presents: Cannabis for Glaucoma

In the post-prohibition age, new applications for medical cannabis are emerging all the time, including in the treatment of glaucoma. Today we are discussing cannabis for glaucoma, one of the most pernicious and common ocular diseases.

The Expanding Medical Cannabis Market

Legal medical cannabis is currently available across the United States, and cannabidiol (CBD) products containing low or no psychoactive properties are even more accessible. Many countries around the world have adopted liberal regulatory cannabis policies, and this shifting legal landscape has opened the floodgates of cannabis research.

Cannabis-based therapies are increasingly accepted as an efficient treatment for a wide range of health challenges, including epilepsy, endometriosis, and chemotherapy-related side effects. One emerging application for cannabis is in the treatment of ocular diseases.

While researchers continue to study how cannabinoids interact in the eye and how these effects can improve eye health, there is long-standing evidence that THC can reduce intraocular pressure (IOP).

What does this mean for people facing ocular disease and is what is the benefit of cannabis for glaucoma?

Cannabis for Glaucoma

The main risk factors of glaucoma are age, genetics, and diabetes. However, in most cases, increasing inflammation leads to elevated IOP that contributes to the destruction of the retina and optic nerve, and eventually end-stage blindness. Therefore, lowering IOP is imperative in halting the progression of glaucoma.

The human eye relies on a delicate balance to function. In the anterior chamber between the cornea and the lens, a clear fluid called the aqueous humor circulates between the lens and the cornea. In a healthy eye, this circulation of fluid is constantly regulated. IOP increases when drainage does not keep up with fluid production: pressure builds up, leading to permanent damage to the retina and optic nerve.

Currently, there are several eye drops available that decrease fluid production and/or increase drainage in the aqueous humor. These treatments are not always effective over time, and some carry unpleasant side effects. A second treatment option is surgical, including laser and microsurgery, for specific conditions. However, these surgeries may need to be repeated several times.

These two courses of glaucoma treatment have decreased the incidence of end-stage blindness, but are not invariably effective.

Getting Cannabis for Glaucoma into the Eye

Clinical studies have shown that cannabinoids reduce intraocular pressure (IOP) at least as well as most conventional glaucoma medications when administered orally, intravenously, or by inhalation.

These modes of drug-delivery significantly reduce IOP in a statistically significant number of glaucoma patients and healthy adults with normal IOP, and maintained this effect for three to four hours. Another potential effect of cannabinoids on the eye apart from lowering IOP is neuroprotective.

By acting on specific ocular receptors, isolated cannabinoid molecules have demonstrated limited efficacy in protecting the optic nerve from damage and restoring blood supply.

While it is known that cannabinoids reduce IOP and may offer neuroprotective benefits, the limited duration of effects with currently available treatments entails frequent administration. This is a disadvantage compared to other available treatments with more sustained effects. An additional challenge to cannabinoid-based ocular therapeutics is the difficulty of penetrating the eye barrier.

The human eye is designed to reject any foreign matter, including ocular treatments. This makes treating internal eye conditions such as glaucoma difficult. One way to improve the efficacy of medicines derived from cannabis for glaucoma is developing advanced delivery platforms to bypass the eyes natural defenses.

Nanoencapsulation delivers highly-bioavailable medication to targeted regions, making cannabis for glaucoma a potential alternative to currently available treatments.

The emergence of nanoencapsulated cannabinoid medication offers a dramatic change in the delivery of cannabis-derived ocular medications. With nanoencapsulation, the beneficial effects of cannabis for glaucoma have the potential to improve the lives of millions.

iCANsee: A Vision of the Future of Ocular Care

iCANsee is an Israeli-based ocular health startup and subsidiary of iCAN: Israel-Cannabis developing topical, pharmaceutical grade, cannabinoid-based medications for common eye disorders, including glaucoma.

Utilizing patented nanoencapsulation technology, iCANsee improves efficacy and bioavailability. The development of this leading-edge therapy will address a number of common challenges to cannabinoid-derived medications to the eye. These include:

  • Improved consistency in dosing
  • Improved onset of action via direct, local application compared to indirect methods of consumption
  • Improved bioavailability by bypassing the eye’s structural barriers to absorption
