Integrative Liver-Targeted Therapy for Diabetic Macular Edema: Combining Tauroursodeoxycholate and Traditional Chinese Medicine.
United States69 participantsStarted 2026-07-01
Plain-language summary
Diabetic macular edema is seen in the later stages of diabetic retinopathy with current conventional therapies targeting local vascular dysfunction. These therapies provide transient improvement in vision and are often uncomfortable to persons with diabetic macular edema and financially burdensome. Diabetic macular edema, a complication of diabetes cannot be managed without addressing systemic inflammation. Liver metabolism and functions are implicated in diabetes and evidence suggests that hepatic metabolic dysfunctions are linked to the neuroinflammation and vascular dysfunctions observed in diabetic retinopathy. Nutraceutical supplements like Tauroursodeoxycholate (a bile acid) and modified Qi Ju Di Huang Wan (a traditional Chinese medicine formula) have been found to reduce hepatic and retinal oxidative stress, provide anti-apoptotic, anti-inflammatory, neuroprotective and hepatoprotective effects. This study will provide a non-invasive multi-targeted strategy for the management of diabetic macular edema.
