Key Takeaways:
- Uveitis can lead to inflammatory cells invading and rapidly spreading in the eye’s gelatinous center.
- CBD reduces inflammation by inhibiting cytokine release from immune cells via its interaction with CB2 receptors.
- A dose of 5 mg/kg CBD offers anti-inflammatory and neuroprotective effects by countering oxidative stress, p38 MAPK activation, and microglial activation.
What Do You Need to Know About Uveitis?
Uveitis refers to inflammation of the uvea, the eye’s middle layer. The type of uveitis varies based on the affected part:
- Anterior uveitis (iritis): Inflammation on the outermost layer.
- Posterior uveitis (choroiditis): Inflammation on the inner layer.
- Pan-uveitis: Inflammation of both sides of the uvea.
Inflammatory cells invade the eye’s gelatinous center and spread rapidly. In most instances, the infection arises suddenly and spreads quickly, often leading to blindness.
Uveitis may stem from infections or other causes, including secondary issues like microbial infections (syphilis, herpes, TB), eye injuries, autoimmune diseases (e.g., sarcoidosis), chronic inflammatory conditions (e.g., Crohn’s disease, IBS), certain medications (e.g., Rifabutin), or cancers (e.g., leukemia, lymphoma).
Diagnosis requires a thorough eye examination and lab tests for underlying conditions. Treatment options can 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 numerous therapeutic properties, making it widely sought after for medical uses.
Key benefits of CBD include:
- CBD helps alleviate inflammation in conditions like arthritis and uveitis.
- Provides pain relief without the psychoactive effects associated with THC.
- Possesses neuroprotective properties, beneficial in treating conditions like multiple sclerosis and epilepsy.
CBD vs. THC
Tetrahydrocannabinol (THC) is the primary psychoactive compound in cannabis that induces the “high” feeling. While both CBD and THC present therapeutic benefits, they significantly differ in their effects and applications.
CBD and Uveitis
CBD minimizes inflammation by inhibiting cytokines from immune cells. It interacts with CB2 receptors found on immune cells throughout the body. Beyond CB2 interaction, it can also mitigate oxidative stress and inflammation through various pathways.
Inhibition of p38 MAPK, Microglial, and ROS
The Medical College of Georgia explored whether oxidative stress and p38 MAPK activation lead to retinal inflammation and microglial activation, and whether CBD can alleviate inflammation by obstructing these processes.
Methods
- Microglial cells from newborn rat retinas were isolated.
- TNF-α levels were assessed using ELISA, NO (Nitric oxide) levels were measured with a NO analyzer, and superoxide anion levels were detected using chemiluminescence.
- ROS (Reactive oxygen species) levels were evaluated using 2′, 7’-dichlorofluorescin diacetate.
Results
- LPS (lipopolysaccharide) treatment of retinal microglial cells initiated immediate ROS production, p38 MAPK activation, and elevated TNF-α production.
- Subsequent phases revealed peaks in NO, ROS, and p38 MAPK activation along with changes in microglial morphology. CBD (1 μM) inhibited ROS and p38 MAPK activation, NO, and TNF-α production while preserving cell morphology.
- In LPS-treated rat retinas, macrophage accumulation, microglial activation, ROS, nitrotyrosine levels, p38 MAPK activation, and neuronal apoptosis were noted. Treatment with 5 mg/kg CBD countered these effects.
These findings suggest that CBD shows protective and inhibitory effects against the inflammatory and oxidative processes triggered by LPS treatment in both retinal microglial cells and rat retinas.
Discussion
Oxidative stress drives retinal inflammation and degeneration in uveitis. CBD provides anti-inflammatory and neuroprotective effects by inhibiting oxidative stress, p38 MAPK activation, and microglial activation.
CBD also reduces oxidative stress, macrophage infiltration, TNF-α production, and prevents retinal damage. This suggests that CBD could be a promising treatment option for inflammation-related retinal issues.
Other Studies
Additional research examines CBD’s effects on CB2 receptors. CBD acts as an inverse agonist at the CB2 receptor, meaning it binds to the receptor and produces effects opposite to those of an agonist. It also affects several non-cannabinoid receptors and ion channels and functions through receptor-independent pathways to reduce inflammation.

Manage Uveitis Inflammation with CB2-Selective Cannabinoids
CB2-selective cannabinoids like CBD can aid in managing inflammation caused by uveitis. It alleviates inflammation and pain, contributing to a more relaxed life. The cannabis industry now presents a range of products available through mail-order marijuana, and you can discover suitable CBD options at Hush Cannabis Club Canada.
Frequently Asked Questions
How much CB2-selective cannabinoid must you consume to manage retinal inflammation?
- Starting Dose. A low dose of 2.5 to 5 mg daily to monitor tolerance.
- Therapeutic Dose. The most common dosage ranges from 20 – 40 mg per serving.
- Maximum Dose. Research indicates that a daily intake of 600 mg of CBD is safe. One study even suggested that doses up to 1,500 mg daily are safe and well-tolerated.
Can THC also contribute to reducing inflammation in uveitis?
THC exhibits anti-inflammatory properties. In a clinical trial, marijuana resulted in a 70% reduction in inflammation. The study observed that CB2 cannabinoid receptors experienced the most significant decrease in inflammation.
THC also lowers the production of pro-inflammatory cytokines and inhibits the activation of the brain’s Stat 1 transcription factor, which is involved in the body’s inflammatory response.
Consider products with a 1:1 THC to CBD ratio to benefit from both cannabinoids, as this combination can more effectively target CB2 receptors for enhanced anti-inflammatory outcomes.
Can cannabinoids manage pain associated with uveitis?
Yes. The analgesic effects of cannabinoids operate through multiple mechanisms: they inhibit neurotransmitter and neuropeptide release at presynaptic sites, modulate postsynaptic neuron excitability, activate the inhibitory pain pathway, and reduce neuroinflammatory signaling.
