[text_dd]Marijuana and glaucoma
Marijuana use can be used to treat and prevent the eye disease glaucoma, which increases pressure in the eyeball, damaging the optic nerve and causing loss of vision.
Marijuana decreases the pressure inside the eye, according to the National Eye Institute: “Studies in the early 1970s showed that marijuana, when smoked, lowered intraocular pressure (IOP) in people with normal pressure and those with glaucoma.”
These effects of the drug may slow the progression of the disease, preventing blindness.[/text_dd]
