Glaucoma is an eye condition in which the optic nerve progresses toward becoming harmed after some time, first lessening peripheral vision before potentially prompting all out blindness. One reason for optic nerve harm in glaucoma is higher-than-normal eye pressure (intraocular weight or IOP).
As marijuana has been legalized for medical or recreational use in more U.S. states and Canada, it has turned out to be more visible and discussed as a conceivable treatment for some, health conditions. Research during the 1980s showed a measurable decrease in intraocular pressure for three or four hours in the wake of smoking cannabis or ingesting THC as a pill or injection. Be that as it may, to treat glaucoma and save vision, eye pressure must be controlled 24 hours every day.
To overcome intraocular pressure by 3 to 5 mm Hg — and keep up that decrease — you would need to ingest about 18 to 20 mg of THC six to eight times daily day, consistently. The possible negative impacts on mood, mental clearness and (If smoked) lung health would be huge. You would not have the capable to drive, work machinery or engage several basic activities. Furthermore, the expense of using cannabis each three to four hours, consistently makes it cost-prohibitive for most patients.
As a comparison, alcohol additionally has a moderate intraocular pressure lowering impact for an hour or so after a drink. However, no physician would suggest that you drink alcohol consistently to treat glaucoma. Many other remedies are available that don’t have the side-effects of alcohol.
Studies Haven’t Proven That THC is Efficient or Reliable for Glaucoma Treatment
Studies have been done on THC eye drops, pills and cigarettes. Eye drops prompted burning, irritated eyes and were appeared to not lower eye pressure. A sublingual (set in the mouth under the tongue) THC compound found no decrease in intraocular pressure. For another study, glaucoma patients were offered THC-containing pills as well as cigarettes. Inside nine months every one of them asked to stop because of side effects.
As researchers learn more about glaucoma, they have also come to understand that high intraocular pressure in the fluid at the front of the eye isn’t the main reason of optic nerve harm. Expanding evidence shows that reduced flow of blood to the optic nerve may also cause harm in patients with glaucoma. Marijuana not just lowers eye pressure, it also lowers blood pressure all through the body. Therefore, marijuana can possibly lower the bloodstream to the optic nerve, effectively canceling out the advantage of lowered intraocular pressure.
What About CBD for Glaucoma?
In recent CBD has gotten a great deal of attention and scrutiny. CBD is a subsidiary of cannabis that doesn’t have mood-altering impacts. Yet, much the same as cannabis that is smoked or eaten, there is no accepted, current investigate that demonstrates CBD to be an effective treatment for glaucoma. In fact, one late study demonstrated that CBD may really build IOP, which would make glaucoma worse.
What is the Future of Marijuana for Glaucoma Treatment?
At present, the best way to control glaucoma and prevent vision loss is to lower the pressure in your eye. Your ophthalmologist can treat glaucoma with drug, for example, prescription eye drops, or surgery, depending on the type of glaucoma and how extreme it is.
Researchers are exploring whether the active ingredients in marijuana may yet offer a glaucoma treatment. If the impacts of cannabis compounds can be isolated, made to be long-acting, and the symptoms disposed of, they may prompt new medicines later on. In any case, such improvements require more research and are years from turning into a reality.
