Although the exact pathogenesis of uveitis is not completely understood, cytokines such as IL-2, TNF-α, INF-γ, IL-12, and IL-17 have been detected in patients with active disease, and it is believed that they would be key players in the pathogenesis (Durrani et al., 2004; Levy-Clarke et al., 2014; Dunn, 2015). Here, TNF is linked to uveitis.
