Article Summary:
Glaucoma, a common eye condition in the U.S., is primarily caused by increased intraocular pressure (IOP), which can damage eye tissue and lead to vision loss. Current treatments focus on lowering IOP to prevent further vision impairment.  The American Academy of Ophthalmology advises against using CBD for glaucoma due to its uncertain effects on IOP, supported by mixed research findings:

• A 2022 review found varied effects of CBD on IOP: no effect in some studies, decreased IOP in others, and increased IOP in a few.
• A 2019 review also reported contradictory results, indicating a potential risk of increased IOP with CBD use.
• A 2018 study suggested CBD might interfere with the IOP-lowering effects of THC, making high-CBD cannabis products less effective for glaucoma.

THC has shown more consistent results in lowering IOP. Products high in THC and low in CBD may be more beneficial for glaucoma patients. Licensed cannabis dispensaries can help identify such products.  CBD may increase eye pressure, potentially worsening glaucoma symptoms. Other side effects include eye dryness. Long-term effects of CBD on glaucoma are not well-studied, and there is a risk of exacerbating the condition.  Research suggests CBD affects multiple cannabinoid receptors, including CB1 and GPR18, influencing ocular pressure. More studies are needed to fully understand CBD’s impact on IOP and glaucoma.

• THC may lower IOP but isn’t recommended as a primary treatment due to its short duration of action and potential side effects, such as intoxication.
• A 2020 survey showed that only 7.6% of glaucoma specialists recommended cannabis for treatment, often only in rare instances.

Glaucoma requires medical treatment to prevent complications like blindness. Until more is known about CBD’s effects on ocular pressure, it’s not safe to use for glaucoma treatment. While THC can lower IOP, it’s not an ideal solution due to its limitations and side effects. Consulting a healthcare professional is essential for safe and effective glaucoma management.
