Figure 2. VEGF levels in vitreous body and serum samples from PDR and MH patients. The vitreous levels of VEGF were higher (p<0.01) in PDR (798.2±882.7 pg/ml; n=14) than in MH (17.7±15.5 pg/ml; n=14). On the other hand, the serum levels of VEGF were no significant differences (p=0.83) between PDR (177.9±155.5 pg/ml; n=9) and MH patients (151.3±96.8 pg/ml; n=9). Double asterisk (**) denotes p<0.01 based on the Kruskal–Wallis test.
