[CANNABIS AND GLAUCOMA: AN ANCIENT LEGEND OR A NOVEL THERAPEUTIC HORIZON?].

[Article in Hebrew]

Abstract

Glaucoma causes damage to the optic nerve and compromises the visual field. The main risk factor of the disease is the level of the intra-ocular pressure. Therapeutic options include medical and surgical treatment, aimed to lower the intra-ocular pressure. Consumption of the cannabis plant (Cannabis Satival has been known since ancient times. It can be consumed orally, topically, intra-venous or by inhalation. The main active ingredient of cannabis is THC (Tetra-Hydro-Cannabinol). One of THC's reported effects is the reduction of intra-ocular pressure. Several studies have demonstrated temporary intra-ocular pressure decrease in both healthy subjects and glaucoma patients following topical application or systemic consumption. The effect was a short term one. It was followed by the development of resistance to the drug after prolonged intake and it was also accompanied by topical and systemic side effects. Cannabis may be considered as a therapeutic option in glaucoma. Its limited effect, development of resistance, acquired side effects and the accompanying psycho-active influence limit its advantage and cause its efficacy to be dubious. Therefore, cannabis treatment for glaucoma currently seems impractical and is not recommended by either the Israeli or the American glaucoma societies.
