Lactiplantibacillus Plantarum 299v Probiotic Supplementation in Patients With Diabetic Macular Edema

Summary

This pilot prospective, interventional, longitudinal study, aims to evaluate the potential benefits of the probiotic supplement Lactobacillus plantarum 299v in patients with diabetic macular edema (DME). The study seeks to address the following questions: 1. Does central macular thickness on optical coherence tomography decrease after 4 months of supplementation? 2. Is visual acuity improved at 1, 2, 3, and 4 months following initiation of supplementation? 3. Is the number of anti-VEGF injections reduced following initiation of supplementation? Outcomes will be compared to a control group, using historic retrospective data. Participants will take Lactobacillus plantarum 299v orally twice daily for four months.
