Summary
This phase 2 trial tests whether a modified Chinese herbal formula, Shenling Baizhu San, can reduce swelling in the retina (macular edema) and improve vision. Adults diagnosed with macular edema take either the herbal granules or a placebo twice daily for 12 weeks. The study measures changes in retinal thickness and visual clarity to see if the formula offers a safe, effective treatment.
