The American Glaucoma Society stated the following in its Aug. 10, 2009 "Position Statement on the Marijuana and the Treatment of Glaucoma," available on its website on confirmed as current position on Apr. 7, 2014:

“[T]he mainstay of treatment for glaucoma patients is lowering the IOP [intraocular pressure]… Although marijuana can lower the intraocular pressure (IOP), its side effects and short duration of action, coupled with a lack of evidence that it use alters the course of glaucoma, preclude recommending this drug in any form for the treatment of glaucoma at the present time.”
