ABSTRACT
PURPOSE: To assess the safety and efficacy of intravitreal infliximab (1 mg/0.05 mL) in patients with refractory posterior uveitis in Behcet's disease. METHODS: Twenty patients were included in this study. Best corrected visual acuity (BCVA), vitreous haze (graded 0-4), vasculitis, retinitis, and papillopathy (presence or absence) were assessed at baseline, Day 1 and Week 2, 4, 6, 8, 12, and 18. Optical coherence tomography (OCT) central foveal thickness, fluorescein angiography, and flash electroretinogram were done at baseline and 4, 12, and 18 weeks. RESULTS: Mean baseline logMAR BCVA was 0.94 (20/160), had improved significantly by Week 2 to 0.6 (20/80) (P < 0.0001), and reached 0.36 (20/40) by Weeks 18 with three injections (P < 0.0001). Mean central foveal thickness OCT decreased significantly from baseline 361 µm to 180 µm at the end of follow-up (P < 0.0001). Profound decrease in mean vitreous haze gradings from two to 0.2 by the end follow-up (P < 0.05). There was a significant reduction in the number of patients with vasculitis (15 at baseline to 1 weeks at 18 weeks), retinitis (nine at baseline to none at 4 weeks), and papillitis (two at baseline to none at 4 weeks) (P < 0.05). No significant electrophysiological changes or ocular adverse inflammatory reactions were observed during the study period. CONCLUSION: Intravitreal infliximab appeared to be safe and effective in treating uveitis in Behcet's disease and should be considered as an alternative to systemic therapies.
