Treat Glaucoma While You Sleep
Scientists have long known that cannabigerolic acid, a compound from the cannabis (aka marijuana) plant, can relieve glaucoma symptoms, but the key elements don’t easily dissolve and therefore can’t be turned into effective eye drops. Researchers at the University of British Columbia may have solved that problem with a compound called a hydrogel. The hydrogel is administered as drops that then form a sort of lens upon contact with the eye, allowing the cannabigerolic acid to dissolve during the night and penetrate the cornea. In pig corneas, which are similar to human corneas, the gel was absorbed quickly; the next step is to test the gel in human eyes.
