The risk/benefit ratio of glucocorticoid therapy can be improved by proper use. Careful monitoring and using appropriate preventive strategies can potentially minimize side effects.

Behçet disease is a chronic relapsing multisystem inflammatory disorder. Ocular involvement is characterized by a bilateral recurrent non-granulomatous panuveitis and retinal vasculitis. Posterior segment findings vary during the course of the disease, in parallel with the relapsing and remitting intraocular inflammation. Structural alterations occur with increased disease duration. Fluorescein angiography is the gold standard in revealing the extent and severity as well as the leaky and/or occlusive nature of retinal vasculitis. Multimodal imaging using color fundus photography, fluorescein angiography, and optical coherence tomography is essential in visualizing diagnostic features, detecting structural changes, and monitoring disease activity and response to treatment in patients with Behçet uveitis.

ABSTRACT.Purpose: To report the outcomes of tocilizumab treatment for refractory ocular inflammatory diseases. Methods: A retrospective case series of 17 patients (28 eyes) diagnosed with recalcitrant ocular inflammatory diseases including uveitis (10 cases), scleritis (six cases) and orbital pseudotumour (one case), who received tocilizumab between April 2010 and March 2015. All patients were initiated with treatment of 4 mg/kg or 8 mg/kg tocilizumab. The primary outcome was absence of inflammation and achievement of steroid sparing at 6 and 9 months. Secondary outcomes were change in visual acuity and major adverse effects of tocilizumab causing discontinuation of the treatment. Results: Mean age at initiation of tocilizumab was 41 AE 16 years. Prior to tocilizumab treatment, all patients underwent unsuccessful conventional immunosuppressive therapy while 94% of patients (16/17) failed treatment with various biological agents. After tocilizumab administration, control of inflammation and steroid sparing were achieved in 63% and 71% of uveitis patients at 6 and 9 months, while 50% of scleritis patients achieved the primary outcome at 6 and 9 months. Mean duration of tocilizumab therapy was 12.6 AE 10.0 (range, 2-35) months. Three of four patients who had a follow-up of at least 18 (range, 18-35) months experienced quiescent inflammation for up to 32 months of tocilizumab use until last visit. Four patients (24%) discontinued tocilizumab due to serious side effects including neutropenia, unacceptable dizziness and nausea, severe angioedema and severe abdominal pain. Conclusion: Our series demonstrated moderate efficacy of tocilizumab in recalcitrant uveitis and scleritis. Serious adverse effects were not uncommon.
