Background MMP-9 plays a prominent role in inflammation and MMP-14 take part in angiogenesis. The objective of this study is to compare MMP-9 and MMP-14 levels between diabetic and non-diabetic patients. Methods The patients who scheduled for pars plana vitrectomy were included in our study. Patients are divided into 2 groups: the diabetic group and non-diabetic group. Age, gender, intraocular pressure(IOP), visual acuity (VA) were reported. Color fundus photography, fundus fluorescein angiography, optic coherence tomography (OCT) were performed before and after the operation. MMP-9 and MMP-14 levels in vitreous samples were analyzed with a reader device by ELISA method. Mann-Whitney U test and logistic regressions were used in statistical analysis, p < 0.05 accepted as statistically significant. Results 70 eyes of 70 patients who received pars plana vitrectomy were enrolled in the study and divided into 2 groups: 34 patients in the diabetic group, 36 patients in the non-diabetic group. The average age of diabetic patients was 60.14 +/- 10.20, and non-diabetic patients was 64.22 +/- 11.16, respectively. The average MMP-9 (0.67 +/- 0.66 ng/ml) and MMP-14 (0.16 +/- 0.45 ng/ml) values in the diabetic group were significantly higher than the average MMP-9 (0.21 +/- 0.05 ng/ml) and MMP-14 (and 0.07 +/- 0.02 ng/ml) values in the non-diabetic group (P < 0.01). Also, it was observed that MMP-9 and MMP-14 levels increases as the diabetic disease duration increases. The risk of diabetes incidence increased with high levels of MMP-9 and MMP-14. Conclusion Due to the higher levels of MMP-9 and MMP-14 in the pathogenesis of diabetic retinopathy, these proteins may probably be among the therapeutic targets in the prevention and treatment of retinopathy.
