The IFN-γ and IL-2 levels in the aqueous humour and serum were greater in samples from patients with uveitis than in those from controls, but the IFN-γ levels in the peripheral blood (39.26 ± 34.11 pg/ml) were greater than those in the aqueous humour (13.86 ± 1.68 pg/ml) among these patients. Here, IL2 is linked to uveitis.
