Figure 2. Correlation between vitreous levels of interleukin-6 and vascular endothelial growth factor from 19 patients with Eales’ disease in the proliferative stage. The interleukin-6 (IL-6) levels in vitreous were correlated significantly with vitreous vascular endothelial growth factor (VEGF) levels (Spearman’s correlation coefficient; r=0.5834, p=0.0087). The solid line represents the linear regression curve of the best fit.
