Figure 4. Vitreous protein concentration in study subjects according to −174G/C genotype. Vitreous concentrations of: A: interleukin-6 (IL-6) and B: vascular endothelial growth factor (VEGF) in patients with Eales’ disease (ED) at the proliferative stage and control patients for each −174G/C genotype. The Mann–Whitney U test was performed to determine whether significant differences were present within the same groups of subjects with different −174G/C genotypes. The results of this analysis are indicated in brackets. An asterisk denotes a significant p value.
