Objective: To compare the efficacy of TNF inhibitors (adalimumab (ADA) and infliximab (IFX)) vs tocilizumab (TCZ) in patients with refractory cystoid macular edema (CME) due to Behçet's disease (BD)., Methods: Multicenter study of patients with BD-associated CME refractory to conventional and/or biological immunosuppressive drugs. From a cohort of 177 patients treated with anti-TNF and 14 patients treated with TCZ, we selected those with CME at baseline. We analyzed the evolution of macular thickness (main outcome), best-corrected visual acuity (BCVA) and intraocular inflammation (Tyndall and vitritis) from baseline up to 4 years in the 3 groups mentioned., Results: 49 patients and 72 eyes with CME were included. ADA was used in 25 patients (40 eyes), IFX in 15 (21 eyes) and TCZ in 9 (11 eyes). No statistically significant baseline differences were observed between the 3 groups except for a lower basal BCVA in TCZ group and a higher basal degree of intraocular inflammation in ADA group. Most patients from all groups had received several conventional immunosuppressive drugs. In addition, most patients in the group of TCZ had also received anti-TNF agents. Biological therapy was used in monotherapy (n=8) or combined with conventional immunosuppressive drugs (n=41). Macular thickness progressively decreased in the 3 groups, with no signs of CME after 1 year of treatment. Similarly, BCVA improvement and inflammatory intraocular remission was achieved in all groups., Conclusion: Refractory CME associated with BD uveitis can be effectively treated either with ADA, IFX or TCZ. Furthermore, TCZ is effective in patients resistant to anti-TNF therapy., Competing Interests: Declaration of Competing Interest Disclosures that might be interpreted as constituting of possible conflict(s) of interest for the study: B.
