(A) Both metalloproteinase (MMP)-1 and MMP-9 concentrations were significantly higher in pan-retinal photocoagulation (PRP)-treated eyes. (B) MMP-9 concentration was significantly higher in DM eyes with diabetes ≥ 10 years. But there was no significant difference in level of MMP-1 between the two groups. (C) The eyes showed recurrence within 3 months of diabetic macular edema had significantly higher MMP-9 levels than non-recurrent eyes. But there was no statistical difference between the two groups in expression of MMP-1.
