In a podcast interview, pharmacologist Mahmoud ElSohly, director of the University of Mississippi’s Marijuana Research Project, discussed the history of how an eye doctor discovered that cannabis can relieve the interocular pressure associated with glaucoma. But while the THC in the plant treated the symptoms, it also means patients experience the high.
“The best way to treat glaucoma is not to take a drug that will affect your brain, affect your ability to function, the whole rest of your body just to lower the pressure inside the eyes,” ElSohly argued. “The way to do this is to develop, let’s say, eye drops, eye drops from marijuana.”
Both his lab and a separate, unnamed company that licensed the idea are looking into the eye drop possibility, with the company having already begun clinical trials, ElSohly said. It’s a notable advancement because THC is lipophilic, acting like an oil, and so “it doesn’t penetrate into the inner compartments of the eye to lower the pressure.”
“Therefore, only if you take systemically—meaning if you inhale it or swallow it or something—but then you deal with all the side effects of THC,” he said in the interview, which was recorded in February and published this month. “Now we’re developing a pharmaceutical product, and it’s been licensed by the way now, that we take the THC molecule and we modify it in a certain way to allow it to go inside the eye, and once inside, it breaks off and releases THC just in the eye to lower the pressure.”
