Popis: Abstract Purpose The aim of this study was to assess the functional and clinical impact of intravitreal administration of a neutralizing anti-IL-6 antibody in the treatment of experimental autoimmune uveitis (EAU) in mice. Methods EAU was induced in 17 female B10.RIII mice by administering Inter-Photoreceptor-Binding-Protein (IRBP) in complete Freund’s adjuvant, followed by a boost with Pertussis toxin. Intravitreal injections of anti-Interleukin (IL)-6 antibody were administered on days 10, 13, and 16 after EAU induction (day 0) into the randomized treatment eye, with an isotype antibody similarly injected into the fellow control eye. Visual acuity was assessed using the optomotor reflex via OptoDrum, and clinical scoring was performed via fundus imaging (utilizing 6 EAU grades) in a single-blinded manner on days 0, 10, 13, 16, and 18. Results Uveitis developed in all 17 mice. Significantly higher visual acuity was observed in treated eyes compared to control eyes on days 13, 16, and 18. The most pronounced effect was noted on days 16 and 18 (p
