In a 1979 study published in the International Journal of Pharmacology and Biopharmacology, 16 patients suffering from open-angle glaucoma, which is caused by the slow clogging of the drainage canals, experienced positive results after using CBD. CBD was found to reduce blood pressure and trigger an increase in heart rate, the combined effect of which lowered intraocular pressure. The effects of CBD sustained longer in patients with hypertension.
Increasing Interest in Cannabinoid-Derived Medication for Glaucoma
In late-stage glaucoma, where doctors are most concerned with alleviating symptoms, the use of medical marijuana is viewed positively. Patients can enjoy significant pain relief and avoid excessive nausea, though they may not be able to do much about the condition itself.
Cannabinoids have also been seen to have protective effects against retinal damage. Damage to the retina can occur with the aging process. Though vitamins can help counteract some of the damage, degeneration from a progression in age is difficult to stem entirely. The good news is that research has indicated that cannabinoids may function as neuropathic agents and help in slowing down loss of vision resulting from retinal conditions such as retinitis pigmentosa. Studies have also suggested the ability of cannabinoid in enhancing the sensitivity of retinal cells to light, improving low-light vision and blazing a path towards more research on the use of medical cannabis in the treatment of degenerative eye diseases.
