Humira is a biologic that blocks TNF-α and can lower the inflammatory response. Studies show about 60–70% of patients have obvious symptom improvement after use, vision stabilizes or improves, and the risk of vision loss can be reduced by about 30%. Of course there are side effects, the most common being infections or rashes, and doctor follow-up and monitoring are needed. When the doctor explained the mechanism, I imagined the “alarm” in my body being turned down, which made the effect intuitive and easier to accept.
