Estimated reading time: 2 minutes A new study has suggested that the cannabinoid, CBN, shows promise as a potential treatment for glaucoma.  A recently-published study has found that cannabinol (CBN) may be an effective treatment for the eye condition glaucoma. Glaucoma is a common eye condition where the optic nerve, which connects the eye to the brain, becomes damaged. Most cases are caused by a build-up of pressure in the eye when fluid is unable to drain properly. Symptoms include blurred vision, eye pain, headaches and without treatment it can lead to blindness. Anecdotal evidence suggests that cannabis may help lower the pressure and improve symptoms of glaucoma, but until now, no products have been investigated in clinical trials. Cannabinol (CBN) is a non-intoxicating cannabinoid, derived from THC and often found after prolonged storage at higher temperatures. Canadian company, InMed Pharmaceuticals is currently conducting preclinical studies on its CBN formulation as a potential treatment for glaucoma, the findings of which have been published in the peer-reviewed journal Biochimica et Biophysical Acta (BBA – Molecular Basis of Disease). Researchers at the University of British Columbia, in association with InMed Pharmaceuticals found that CBN,  conducted several studies to evaluate the survival of retinal ganglion cells [a type of neuron located near the retina], modulation of pressure in the eye and its effects on extracellular matrix proteins, which support and surround the cells, using cell and animal models. Researchers found that CBN promotes neuroprotection and normalises pressure in the eyeball to help prevent damage caused by the condition.  They also compared the effects of CBN with other cannabinoids, including cannabidiol (CBD) and tetrahydrocannabinol (THC), with results indicating that CBN has a stronger effect and broader neuroprotective therapeutic range. The study concludes: “Our observations in the present study indicate a therapeutic potential for CBN…
