Effect of oral tranexamic acid for macular edema associated with retinal vein occlusion or diabetes

Tranexamic acid (TXA) is a widely used plasmin inhibitor that can also cause a decrease in vascular permeability. We hypothesized that TXA could improve macular edema that has originated from an increase in retinal vascular permeability. The aim of this study was to evaluate the efficacy of oral TXA for macular edema associated with retinal vein occlusion (RVO) or diabetic macular edema (DME).
