Fig 2. Dot plots of immune mediators, IL-1β, IL-6, IFN-γ and TNF-α. IL-1β, IL-6, IFN-γ and TNF-α in serum of noninflammatory controls patients (cataract age-related) (CTL) (N = 36) as compared with immune mediators in the serum of patients with idiopathic uveitis (n = 51) but differences in both groups are not significant.

Note that few isolated patients with idiopathic uveitis had cytokines increased in serum samples. * = P<0.05; ** = P<0.01; *** = P<0.001.
