Key Takeaways:
- Uveitis can lead to inflammatory cells invading and rapidly spreading within the eye’s gelatinous center.
- CBD can diminish inflammation by hindering cytokine release from immune cells through its interaction with CB2 receptors.
- A dosage of 5 mg/kg CBD offers anti-inflammatory and neuroprotective effects by obstructing oxidative stress, p38 MAPK activation, and microglial activation.
What Do You Need to Know About Uveitis?
Uveitis refers to inflammation of the uvea—the middle layer of the eye. The type of uveitis varies based on which part of the uvea is affected:
- 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 invade the eye’s gelatinous center, often starting suddenly and spreading quickly. The condition is poorly understood and can lead to blindness.
Uveitis may stem from infections or other causes, including autoimmune diseases, chronic inflammatory conditions, certain medications, or cancers.
Diagnosis requires a comprehensive eye examination and tests for underlying issues. Treatment may include surgery, antibiotics, antiviral medications, and anti-inflammatory drugs like cortisol.
What is CBD?
Cannabidiol (CBD) is a non-psychoactive cannabis compound known for its therapeutic properties, making it a favored option for medical use.
Key benefits of CBD include:
- CBD helps reduce inflammation in conditions like arthritis and uveitis.
- Provides pain relief without the psychoactive effects associated with THC.
- Exhibits neuroprotective properties beneficial in conditions such as multiple sclerosis and epilepsy.
CBD vs. THC
Tetrahydrocannabinol (THC) is the primary psychoactive compound in cannabis responsible for the “high” sensation. While both CBD and THC possess therapeutic benefits, they have distinct effects and applications.
CBD and Uveitis
CBD can alleviate inflammation by inhibiting cytokines from immune cells. It interacts with CB2 receptors on immune cell surfaces. Besides CB2 interaction, CBD can reduce inflammation and oxidative stress through various pathways.
Inhibition of p38 MAPK, Microglial, and ROS
Research from the Medical College of Georgia explored whether oxidative stress and p38 MAPK activation induce retinal inflammation and microglial activation, and whether CBD can mitigate these processes.
Methods
- Microglial cells were isolated from newborn rat retinas.
- TNF-α levels were measured using ELISA, NO levels with a NO analyzer, and superoxide anion levels via chemiluminescence.
- ROS levels were evaluated using 2′, 7′-dichlorofluorescin diacetate.
Results
- LPS treatment of retinal microglial cells led to immediate ROS production, p38 MAPK activation, and increased TNF-α production.
- CBD (1 μM) inhibited ROS and p38 MAPK activation, maintaining cell morphology.
- In LPS-treated rat retinas, various negative effects were observed, but 5 mg/kg CBD treatment blocked these outcomes.
These findings show that CBD has protective and inhibitory effects against inflammation and oxidative processes in retinal microglial cells and rat retinas.
Discussion
Oxidative stress drives retinal inflammation and degeneration in uveitis. CBD provides anti-inflammatory and neuroprotective effects by blocking oxidative stress, p38 MAPK activation, and microglial activation.
CBD also reduces oxidative stress and inflammation, indicating its potential as a treatment for inflammation-related retinal issues.
Other Studies
Various studies investigate CBD’s effects on CB2 receptors. CBD acts as an inverse agonist at the CB2 receptor, binding and producing effects opposite to an agonist. It also influences several non-cannabinoid receptors and pathways to reduce inflammation.

Manage Uveitis Inflammation with CB2-Selective Cannabinoids
CB2-selective cannabinoids, including CBD, can effectively manage uveitis-related inflammation. They reduce pain and promote a less stressful life. Explore suitable products at MMJDirect Canada for your needs.
Frequently Asked Questions
How much CB2-selective cannabinoid should you consume for retinal inflammation management?
- Starting Dose: A low dose of 2.5 to 5 mg daily to evaluate tolerance.
- Therapeutic Dose: Commonly 20 – 40 mg per dose.
- Maximum Dose: A daily dose of 600 mg of CBD is considered safe, with some studies suggesting tolerability up to 1,500 mg daily.
Can THC also contribute to reducing inflammation in uveitis?
THC shows anti-inflammatory properties. In clinical trials, it significantly reduced inflammation, particularly at CB2 receptors.
THC also inhibits pro-inflammatory cytokine production, suggesting that a balanced THC to CBD ratio can enhance anti-inflammatory effects.
Can cannabinoids manage pain associated with uveitis?
Yes, cannabinoids alleviate pain through various mechanisms, reducing neurotransmitter release and modulating neuronal excitability.
