From the American Academy of Ophthalmology:
If you were hoping that CBD, or cannabidiol, would offer a natural glaucoma remedy, the latest research is a downer. A new study suggests that CBD doesn’t lower eye pressure, it raises it. That’s bad because high eye pressure is the primary risk factor for glaucoma, one of the leading causes of blindness in the United States.
Glaucoma is a condition that damages the optic nerve at the back of the eye. It’s the nerve that transmits visual information to the brain, allowing us to see. Glaucoma is often linked to a buildup of pressure inside the eye. The increased pressure can damage the nerve, leading to permanent vision loss.
For their study, researchers from Indiana tested an eyedrop in rats that contained CBD, a component of cannabis that does not get you stoned. They found that it raised pressure inside the eyes by 18 percent for at least four hours after the drops were instilled.
The doctors at Kansas City Eye Clinic warn that if you are diagnosed with Glaucoma or have a family history of Glaucoma, that you get an eye exam and have your eye pressure checked and monitored if you are using CBD oil, topically or ingesting it.
