Glaucoma

Glaucoma refers to medical conditions that lead to gradual optic nerve damage and are commonly associated with increased pressure within the eye (intraocular pressure/IOP).  These conditions can lead to headaches, blurred vision and in severe/chronic cases, vision loss.

Medical marijuana may possibly help treat glaucoma by relieving pain and dropping the intraocular pressure.  This effect is somewhat short lived, giving about four hours of decreased intraocular pressure per use. It, however, is not recommended as an official treatment method for glaucoma by the American Academy of Ophthalmology or the American Glaucoma Society.  This is likely because the routes of administration do not facilitate round the clock intraocular pressure reduction the way that more conventional glaucoma therapies do. Therefore, routine followup with an ophthalmologist or glaucoma specialist is still recommended.
