Among adult Filipino patients with mild Graves’ ophthalmopathy lasting less than 18 months, taking 200 micrograms of selenium daily for six months along with standard eye care results in 61.9% of...
Mechanism
Synthesis from 1 study
Selenium from the pill gets used by cells in the eye to clean up harmful molecules that cause swelling and redness. When these molecules are reduced, the immune system stops overreacting, and the inflammation in the eye goes away.
Most probable mechanism
Selenium from the supplement enters the bloodstream and gets used to make special proteins that clean up harmful molecules in the eye tissues. These proteins reduce damage caused by oxidation, which stops the immune cells from releasing too many inflammatory signals. As a result, swelling, redness, and pain in the eye area decrease, and the inflammation resolves.
Oral selenium is absorbed in the gastrointestinal tract and transported to orbital tissues via selenoprotein P
Selenium is incorporated into selenoproteins such as glutathione peroxidases and thioredoxin reductases within orbital fibroblasts and infiltrating immune cells
Selenoproteins reduce hydrogen peroxide and lipid peroxides, lowering oxidative stress in orbital tissues
Reduced oxidative stress inhibits activation of NF-κB and other pro-inflammatory signaling pathways in orbital fibroblasts
Decreased cytokine production (IL-6, TNF-α, IFN-γ) reduces recruitment and activation of T cells and macrophages in orbital fat and muscle
Reduced inflammation decreases vascular permeability, edema, and tissue remodeling in orbital soft tissues
