What is Glaucoma?

Overview by Medical Marijuana Treatment Clinics of Florida

Glaucoma is a condition that causes damage to the optic nerve, which is responsible for carrying visual information from the eye to the brain. Glaucoma could have a hereditary factor and typically does not appear in patients until they are older than 60, but it is not unheard of for younger people to develop or even be born with the condition. 

See Also from MMTCFL:

Current research evidence highlights that influencing the endocannabinoid system is a promising way to treat glaucoma. Studies show that we can use this system to not only reduce eye pressure but also provide neuroprotection. 

This latter finding is especially significant because some people with glaucoma continue to experience vision loss even after their eye pressure is reduced. As such, there’s a need for glaucoma medicines that address both eye pressure and neuronal damage.

Materials from the Webinar

“Cytokines are signaling proteins that ultimately recruit inflammation to happen. Cytokines will trigger specific immune cells to release inflammation or actually even reduce inflammation, given the right circumstances. […] CBD actually modulates the cytokine production.”
