Key Takeaways:
- Uveitis can lead to the invasion of inflammatory cells in the eye’s gelatinous center.
- CBD reduces inflammation by inhibiting the release of cytokines from immune cells via its interaction with CB2 receptors.
- A dose of 5 mg/kg CBD offers anti-inflammatory and neuroprotective effects by blocking oxidative stress and p38 MAPK activation.
What You Should Know About Uveitis
Uveitis refers to the inflammation of the uvea, which is the middle layer of the eye. The nature of uveitis varies based on which part of the uvea is inflamed:
- Anterior uveitis (iritis): Inflammation on the outermost layer.
- Posterior uveitis (choroiditis): Inflammation on the inner layer.
- Pan-uveitis: Inflammation affecting both sides of the uvea.
Inflammatory cells infiltrate the eye’s gelatinous center, often starting abruptly and spreading rapidly. This disease is still not well understood and has the potential to result in blindness.
Uveitis can arise from infections or various other factors. It may also be secondary to conditions such as microbial infections, eye injuries, autoimmune diseases, chronic inflammatory illnesses, certain medications, or cancers.
Diagnosis requires a thorough eye examination and lab tests for underlying conditions. Treatment options can include surgery, antibiotics, antiviral medications, and anti-inflammatory drugs.
What is CBD?
Cannabidiol (CBD) is a non-psychoactive compound derived from cannabis, known for its multiple therapeutic effects, making it a favored choice for medical use.
Key advantages of CBD include:
- CBD helps mitigate inflammation in conditions like arthritis and uveitis.
- Offers pain relief without the psychoactive effects linked to THC.
- Possesses neuroprotective properties, beneficial for conditions such as multiple sclerosis and epilepsy.
CBD vs. THC
Tetrahydrocannabinol (THC) is the primary psychoactive component in cannabis that induces the “high.” Both CBD and THC provide therapeutic benefits, but they differ notably in their effects and uses.
CBD and Uveitis
CBD aids in reducing inflammation by inhibiting cytokine release from immune cells. It interacts with CB2 receptors located on immune cells throughout the body. Besides interacting with CB2, it can also diminish oxidative stress and inflammation through various pathways.
Inhibition of p38 MAPK, Microglial, and ROS
The Medical College of Georgia explored the impact of oxidative stress and p38 MAPK activation on retinal inflammation and how CBD might alleviate this inflammation.
Methods
- Microglial cells from newborn rat retinas were isolated.
- TNF-α levels were measured using ELISA, while NO levels were assessed with a NO analyzer.
- ROS levels were estimated using 2′, 7′-dichlorofluorescin diacetate.
Results
- LPS treatment of retinal microglial cells initiated immediate ROS production and p38 MAPK activation.
- CBD (1 μM) suppressed ROS and p38 MAPK activation and preserved cell morphology.
- 5 mg/kg CBD treatment inhibited macrophage accumulation and neuronal apoptosis in LPS-treated rat retinas.
These findings suggest that CBD exhibited protective effects against inflammatory and oxidative processes in both retinal microglial cells and rat retinas.
Discussion
Oxidative stress is a driving force behind retinal inflammation in uveitis. CBD provides neuroprotective effects by countering oxidative stress and p38 MAPK activation.
CBD also reduces oxidative stress and prevents retinal damage, indicating its potential as a treatment for inflammation-related retinal issues.
Other Studies
Additional research investigates CBD’s influence on CB2 receptors. CBD acts as an inverse agonist at the CB2 receptor, producing effects opposite to those of an agonist.

Manage Uveitis Inflammation with CB2-Selective Cannabinoids
CB2-selective cannabinoids like CBD can effectively manage inflammation associated with uveitis, promoting a less stressful lifestyle. The cannabis market offers a variety of mail-order marijuana products, available at the Herbal Dispatch Canada cannabis store.
Frequently Asked Questions
What is the recommended dosage of CB2-selective cannabinoids for retinal inflammation?
- Starting Dose: Begin with a low dose of 2.5 to 5 mg daily to evaluate tolerance.
- Therapeutic Dose: Commonly, 20-40 mg per dose is recommended.
- Maximum Dose: A daily dose of 600 mg of CBD is considered safe, with some studies suggesting tolerability for doses up to 1,500 mg.
Can THC also aid in reducing inflammation in uveitis?
THC exhibits anti-inflammatory qualities. A clinical trial indicated that marijuana resulted in a 70% decrease in inflammation, particularly at CB2 receptors.
THC lowers pro-inflammatory cytokine production and inhibits the activation of the brain’s Stat 1 transcription factor, reducing the body’s inflammatory response.
Utilizing products with a 1:1 ratio of THC to CBD may enhance the anti-inflammatory benefits of both cannabinoids.
Yes. The analgesic effects of cannabinoids operate through various mechanisms, such as inhibiting neurotransmitter and neuropeptide release, modulating postsynaptic neuron excitability, and reducing neuroinflammatory signaling.
