Correlation between the severity of macular edema and the vitreous fluid levels of vascular endothelial growth factor (VEGF), soluble intercellular adhesion molecule-1 (sICAM-1), and interleukin-6 (IL-6). In the CRVO group, vitreous levels of VEGF (A), sICAM-1 (B), and IL-6 (C) were significantly correlated with the severity of macular edema (ρ = 0.49, P = 0.029, ρ = 0.66, P = 0.003, and ρ = 0.61, P = 0.006, respectively).
