Although the IFN-γ levels in the AqH samples from the BD patients were significantly higher than the levels observed in the samples from both the VKH and AR groups, we found no correlations between the IFN-γ levels in the AqH and the anterior chamber Flare values (r = 0.481, P = 0.190) and cell counts (r = 0.065, P = 0.790) of the BD patients. This evidence concerns the gene IFNG and Behcet disease.
