Summary

This study tests whether taking a probiotic (Lactobacillus plantarum 299v) twice daily for four months can reduce retinal swelling and improve vision in people with diabetic macular edema. Thirty-six adults with the condition will take the supplement, and their results will be compared to past data from a control group. The goal is to see if this simple addition can lessen the need for eye injections.
